Abstract

This invention provides a work vehicle in which operating switches are easy to operate even in a situation where the vehicle is shaken. In a wheel loader 1 including a working device 2 and a cab 3, wherein the cab 3 is provided with a driver's seat 51, a pair of front pillars 331L, 331R, an operating lever 54 for operating the working device 2, and a switchbox 55 having an operating surface 550 in which multiple operating switches S are arranged, the operating lever 54 is placed between a right front pillar 331R and the driver's seat 51, the switchbox 55 is installed to the right front pillar 331R with its long side direction being along the pillar extension direction, the operating surface 550 is oriented toward a direction along an imaginary line IL that passes through the center in its short side direction and extends perpendicular to the surface, the imaginary line intersecting a backrest of the driver's seat 51 and a center line C with respect to the left and right direction of the cab 3, and one side of the switchbox 55 in a short side direction has a guide 553 formed to overhang out along its long side direction.

First claim

The invention claimed is:

1. A work vehicle comprising a working device installed on a frame structure constituting a vehicle body and a cab mounted on the frame structure, wherein the cab is provided with a driver's seat mounted on a floorboard, a pair of pillars extending in a vertical direction between a ceiling and the floorboard at left and right sides in front of the driver's seat, an operating lever for operating the working device, and a switchbox having an operating surface in which multiple operating switches are arranged,
wherein the operating lever is placed between one pillar of the pair of pillars and the driver's seat in left and right direction of the cab;
the switchbox is installed to the one pillar with its long side direction being along the pillar extension direction and includes a guide overhanging out in one side in a short side direction and formed to be along the long side direction;
in a back side of the guide, a recess continuing along an extension direction of the guide is defined; and;
the operating surface is oriented toward a direction along an imaginary line that passes through the center in its short side direction and extends perpendicular to the surface, the imaginary line intersecting a backrest of the driver's seat and a center line with respect to the left and right direction of the cab.

2. The work vehicle according to claim 1 ,
wherein the guide is formed in a continuous shape along the long side direction.

3. The work vehicle according to claim 1 ,
wherein the cab is provided with a display device disposed in an upper position on the side of the one pillar; and
the operating surface of the switchbox is placed between the display device and the operating lever in a vertical direction.
