Abstract

A working vehicle includes an operator seat and an armrest arranged on a side of the operator seat. The armrest includes an upper surface on which an operation tool arrangement portion is arranged, the operation tool arrangement portion arranging an operation tool, and a side surface having a concave portion. The concave portion is located on an area overlapping, in a front-to-back direction, with another area including the operation tool arrangement portion.

First claim

What is claimed is:

1. A working vehicle comprising:
an operator seat; and
an armrest arranged on a side of the operator seat, wherein
the armrest includes:
an upper surface on which an operation tool arrangement portion is arranged, the operation tool arrangement portion arranging an operation tool; and
a side surface having a concave portion,

the concave portion is located on an area overlapping, in a front-to-back direction, with another area including the operation tool arrangement portion and does not reach the upper surface of the armrest,
the upper surface of the armrest includes a portion that overhangs the concave portion, and
the concave portion is gradually widening in the front-to-back direction from above to below, and is trapezoidal or substantially trapezoidal in a side view.

2. The working vehicle according to claim 1 , wherein
the operation tool includes a plurality of operation tools,
the operation tool arrangement portion arranges the plurality of operation tools in the front-to-back direction, and
the concave portion is provided in the front-to-back direction over an entire length of the other area including the plurality of operation tools are provided.

3. The working vehicle according to claim 1 , wherein
the operation tool arrangement portion arranges a plurality of the operation tools in line in a direction from the side surface having the concave portion to another side surface of the armrest opposed to the side surface.

4. The working vehicle according to claim 1 , wherein
the concave portion is provided on the side surface on an opposite side of the armrest from the operator seat.

5. The working vehicle according to claim 3 , wherein
the concave portion has a size allowing four fingers other than a thumb of an operator seating on the operator seat to be hooked on the concave portion when the operator operates the operation tools arranged on the operation tool arrangement portion.

6. The working vehicle according to claim 1 , wherein
the armrest includes
an elbow rest on which an operator seating on the operator seat places an elbow of the operator,

the operation tool arrangement portion is arranged in front of the elbow rest, and
the concave portion is provided in a region extending in the front-to-back direction over the elbow rest and the operation tool arrangement portion.

7. The working vehicle according to claim 6 , wherein
the elbow rest includes
a front portion having an inclining surface that downwardly inclines toward the operation tool arrangement portion.

8. The working vehicle according to claim 7 , wherein
the inclining surface is provided on the elbow rest on a side closer to the concave portion in a width direction of the armrest.

9. The working vehicle according to claim 1 , wherein
the upper surface having the operation tool arrangement portion includes a region on a side close to the concave portion that is lower in height than another region opposite the region on the side close to the concave portion, the region and the another region being arranged in a width direction of the armrest.

10. The working vehicle according to claim 9 , wherein
the upper surface having the operation tool arrangement portion includes:
one upper surface that is the region on the side close to the concave portion;
another upper surface that is the another region opposite the region on the side close to the concave portion; and
a middle upper surface that is a region provided between the one upper surface and the another upper surface, and

the middle upper surface is higher than the one upper surface and lower than the another upper surface in height.

11. The working vehicle according to claim 10 , wherein
the operation tool includes a plurality of operation tools, the plurality of operation tools including:
a traveling operation tool to be operated to perform a traveling operation; and
a working operation tool to be operated to perform a working operation,

the traveling operation tool is arranged on the one upper surface, and
the working operation tool is arranged on the another upper surface.

12. The working vehicle according to claim 1 , wherein the concave portion has a flat portion which is most deeply recessed from the side surface toward the operator seat, and an inclining portion which slopes down gradually from the side surface to the flat portion.
