Risk of occurrence of a bonding failure at the time when a slit hole is bonded is decreased. A weather strip to be attached to a vehicle has a holding portion having a thin portion where an insertion hole through which a clip is to be inserted is formed, and a thick portion that is formed on at least one of both end sides of the thin portion in the longitudinal direction of a base portion, which is to be attached to an attachment part of the vehicle, so as to be thicker than the thin portion and so as to extend in the short-side direction of the base portion.

A door weather strip includes a first extrusion-molded part which couples to an upper side part of a frame of a door of an automobile, a second extrusion-molded part which couples to a vertical side part of the frame, and a die-molded part which connects the first and second extrusion-molded parts on a corner part. A second extended part extends toward a rear part from the die-molded part and has a rigid member embedded. A body of the rigid member has a single anchoring part which is fit in a hole formed on the vertical side part of a frame and a protrusion provided below the anchoring part. The protrusion is flush with the body and extends toward a front part of the automobile body. The protrusion is capable of abutting with an outer part of a second retainer of the door.

To provide a corner structure capable of making a glass-run body and a sealing part difficult to come apart. A corner structure ( 1 ) of a glass run configured to be attached to an automobile, includes: a glass-run body ( 2 ) configured to be attached to a periphery of a door of the automobile; and a hollow sealing part ( 3 ) configured to fill a parting portion which is present between a front door and a rear door of the automobile, or a parting portion which is present between the rear door and a vehicle body of the automobile. The glass-run body ( 2 ) and the sealing part ( 3 ) are integrally molded.

A weather strip includes an installation base member and a seal member. The installation base member couples to a flange of at least one of a peripheral edge of a panel of an automobile or a peripheral edge of an opening of an automobile body of the automobile. The seal member is integrally molded with the installation base member and makes elastic contact with the other one of the peripheral edge of the opening or the peripheral edge of the panel when the panel is in a closed position. The seal member has a coating film formed on a surface. The coating film is prepared by adding a filler to a base. The filler has an average particle size that falls within a range of 15 to 20 μm and a deformation strength of not more than 0.1 MPa at 10% strain.

A door weather strip for an automobile couples to a flange of a door of the automobile. The door weather strip includes an installation base member, a hollow seal member, an air vent, and a sponge layer. The installation base member couples to the flange. The hollow seal member is integrally molded with the installation base member, and makes elastic contact with an automobile body of the automobile when the door is in a closed position. The hollow seal member includes a first wall, a second wall, a third wall, and a fourth wall. The air vent is provided on the hollow seal member, and is used to release air from the hollow seal member. The sponge layer is provided on an inner peripheral surface of the hollow seal member except the air vent, and has a specific gravity lower than the first, second, third, and fourth walls.

A length of a sub seal of a door weather strip is sized and dimensioned in a manner that a distance is longer than a length with a glass run coupling to an outer-cabin side of a flange of a frame and the door weather strip coupling to an inner-cabin side of a door with a clip. The distance is between part of a lower part of a top end of the sub seal of the door weather strip in contact with an inclined surface of an upper side wall of the glass run and part of an upper surface of a top end of a lip of the glass run. The length is of a perpendicular line that extends between the sub seal and an inclined plate of the frame passing through the part of the upper surface of the top end of the lip.

A glass run for an automotive door, the glass run to be assembled to a window frame of the automotive door from vehicle outside and seal a gap between the window frame and window glass, includes: a glass run body having an insertion groove and attached to a glass run attachment plate extending from an upper portion of the window frame toward the vehicle outside; and a trim strip to be assembled to a side of the glass run body closer to the vehicle outside, the trim strip extending in a vehicle front-rear direction. The trim strip includes a trim strip body made of resin and formed through extrusion molding, and a decorative tape coextruded on a side of the trim strip body closer to the vehicle outside.

Risk of occurrence of a bonding failure at the time when a slit hole is bonded is decreased. A weather strip to be attached to a vehicle has a holding portion having a thin portion where an insertion hole through which a clip is to be inserted is formed, and a thick portion that is formed on at least one of both end sides of the thin portion in the longitudinal direction of a base portion, which is to be attached to an attachment part of the vehicle, so as to be thicker than the thin portion and so as to extend in the short-side direction of the base portion.

A first molded part with a first concave-shaped part is provided on a front door, and a second molded part with a second concave-shaped part is provided on a rear door. The first and second molded parts make elastic contact with a main seal provided on an automobile body of a center pillarless automobile, to seal a gap between the doors. A rear surface of a first rear wall of the first concave-shaped part and a front surface of a second front wall of the second concave-shaped part of a sealing structure for a door of an automobile each have an upper part and an outer-cabin side part inclined toward a front part of the automobile body. The front surface makes elastic contact with the rear surface when the doors are in closed positions.

A weather strip couples to a flange with curved parts of a sliding door of an automobile. The weather strip includes an installation base member, a hollow part, and an insert. The installation base member couples to the flange and includes an inner-cabin side wall, a first outer-cabin side wall, and a connecting wall. A part of the installation base member which couples to the curved parts is cut out, to provide a cut-out portion. The cut-out portion is subjected to die molding, to provide a die-molded part. The hollow part is integrally formed with the installation base member by extrusion molding. The insert is shaped in conformance with the curved parts and is embedded in the die-molded part with a plurality of concave shaped parts of the insert abutted with a plurality of pins of a die under the die molding.
