A soil-and-sand intrusion preventing structure includes: a rear door; a bumper disposed to protrude more downward and rearward than the rear door when the rear door is closed; a soil-and-sand intrusion preventing wall member that extends longer than an opening range of an opening between rear end wall portions of body frames disposed on the left and right sides of a vehicle body, and is fixed to an upper surface of the bumper; and a flexible trim mounted on a trim mounting plate disposed inside and below a peripheral edge of a rear door frame constituting the rear door, the flexible trim having a planar shape that follows a planar shape of the soil-and-sand intrusion preventing wall member, wherein the trim is brought into contact with the soil-and-sand intrusion preventing wall member over an entire length thereof when the rear door is closed.

A working vehicle includes an upper body having a device compartment, and a hydraulically operating working device, the device compartment being provided with an electric motor as a drive source of the working device, a driven device driven by the electric motor, a motor bracket supporting the electric motor, and a vehicle body-side bracket supporting the motor bracket, the motor bracket being installed to the vehicle body-side bracket via an anti-vibration support having an anti-vibration function and providing support, at two parts of a lower part and one part of an upper part, with at least two sets of the electric motor on one side of a predetermined direction and the driven device on the other side arranged one above the other.

Maintenance of components to be maintained is facilitated in a working vehicle equipped with an electric motor as a driving source of a working unit. A working vehicle 1 includes an upper slewing body, a lower traveling body, working units that is operated by hydraulic pressure, an electric motor for driving the working units, a battery pack for supplying power for driving the electric motor: a battery pack compartment for installing the battery pack: and a battery cover that is openable and covers an opening in the battery pack compartment. In the battery pack, at least a battery management unit board, a cell management unit board, a charging fuse, and a service plug are disposed as the components to be maintained at positions within a reach of a maintenance worker's hand through the opening.

An armrest device includes an armrest part and a position adjustment mechanism supporting the armrest part in a position-adjustable manner, the position adjustment mechanism including a first plate immovable in relation to a seat, a second plate movable in upward and downward directions in relation to the first plate, a third plate movable in forward and backward directions in relation to the second plate and having the armrest part attached, and a fastening member fastening the first, second, and third plates, the fastening member including a screw member inserted in a guide hole in the first plate, a penetration hole in the second plate, and a guide hole in the third plate, and a manually operated knob screwed with the screw member.

A working vehicle includes a relay component and three chargers for a single-phase alternating-current power supply to supply electric power to an electric motor. Selected as the relay component and mounted to the vehicle body is a first relay component when the external power supply PS is a three-phase alternating-current power supply and the power cable Ca has an output plug PgA of a four-wire type including a ground wire, a second relay component when the external power supply PS is the three-phase alternating-current power supply and the power cable Ca has an output plug PgB of a five-wire type including the ground wire, or a third relay component when the external power supply PS is a single-phase alternating-current power supply and the power cable Ca has an output plug PgC of a three-wire type including the ground wire.

A working vehicle includes: a filler port having a resiliently deformable hose communicating with a liquid storage part, a lid mechanism mounted to an upper end of the hose to open and close the filler port, and a moving mechanism. The moving mechanism includes: a fixing part pivotably coupled to the vehicle body and having the lid mechanism or the hose; an operating part pivotably coupled to the fixing part and including a knob; and a slide support fixed to the vehicle body and including a sliding hole for slidably inserting the knob therethrough to define a sliding range, and a locking recess. The fixing part or the operating part includes a locking projection.

A working vehicle is provided that can easily perform a mounting and detaching operation of a battery therein. A working vehicle includes: a body frame; and a counterweight that is mounted on a vehicle rear portion of the body frame. The counterweight is mounted on the body frame by a plurality of fixing bolts that threadedly engage with the counterweight by way of the body frame from a lower surface side of the body frame.

There is provided a working vehicle facilitating the attachment/detachment of a battery pack. A working vehicle has a vehicle body, a travel unit, a working unit working by a hydraulic pressure, and an electric motor serving as a drive source for the travel unit or the working unit; the vehicle body includes a main body frame provided in a lower portion and serving as a reinforcing member and a support member for on-board devices; the main body frame includes a large plate serving as a bottom plate; the large plate has a cutout area provided in a rear portion, facing backward in a plane view, and allowing the support section of a device loading/unloading a battery pack to abut on the cutout area, and the battery pack is disposed above the cutout area.

An operation control system includes a control device having a hydraulic pump control unit that controls a hydraulic pump based on a level that an operator selects from levels in n stages (n being an integer of 2 or more). The hydraulic pump control unit has operation distance/current value corresponding data where an operation distance of an operating lever and a current value are made to correspond to each other in a corresponding manner with each level in the levels in n stages. A current value that corresponds to an operation distance of the operating lever at a present point of time is acquired from the operation distance/current value corresponding data that corresponds to the level that the operator selects, and controls the discharge amount of a pressurized oil that the hydraulic pump discharges based on the acquired current value.
