Abstract

Provided is a cab which can improve the workability of ripping. The cab includes an operator's seat placed in the cab and a right armrest placed rightward of the operator's seat in the cab. A front end portion of the operator's seat is tilted rightward with respect to a front-rear direction (the direction of X) of the cab as seen in a plan view. The right armrest includes a front region including a front end of the right armrest and a rear region including a rear end of the right armrest. The rear region includes a portion placed at a shorter distance from a midline bisecting the operator's seat as seen in a plan view, than a distance between the front region and the midline.

First claim

The invention claimed is:

1. A cab for a work vehicle, comprising:
an operator's seat placed in said cab so that a front end portion of said operator's seat is tilted rightward with respect to a front-rear direction of said cab as seen in a plan view; and
an armrest placed rightward of said operator's seat in said cab,
said armrest comprising a front region including a front end of said armrest and a rear region including a rear end of said armrest,
a right edge of said armrest extending in parallel with the front-rear direction of said cab as seen in the plan view,
a left edge of said front region extending in parallel with a midline bisecting said operator's seat as seen in a plan view,
said midline tilting with respect to the front-rear direction of said cab, so that the closer the midline is to said armrest's frontmost end the further said operator's seat tilts rightward and the closer the midline is to said armrest's rearmost end the further said operator's seat tilts leftward, and
said rear region including a portion placed at a shorter distance from said midline, than a distance between said front region and said midline.

2. The cab according to claim 1 , wherein a left end of said rear end of said armrest protrudes rearward with respect to a line perpendicular to said midline of the operator's seat and passing a right end of said rear end.

3. The cab according to claim 1 , wherein a left edge of said rear region protrudes toward said midline of the operator's seat with respect to the left edge of said front region.

4. The cab according to claim 1 , wherein a right edge of said rear region includes a portion protruding upward with respect to a left edge of said rear region.

5. The cab according to claim 1 , further comprising a lever for operating a work implement placed rearward of said cab, wherein
said armrest is placed between said lever and said operator's seat.

6. A bulldozer comprising the cab as recited in claim 1 .
