Abstract

A work machine includes a cabin, a machine room, a hydraulic oil tank, a partition wall, and a cover member. The machine room accommodates a drive apparatus to move the work machine. The hydraulic oil tank is provided in the machine room and has an oil gauge. The partition wall separates the cabin from the machine room and has an opening through which the oil gauge is viewable from the cabin. The cover member seals a gap between the partition wall and the oil gauge.

First claim

What is claimed is:

1. A work machine comprising:
a cabin;
a machine room accommodating a drive apparatus to move the work machine;
a hydraulic oil tank provided in the machine room and having an oil gauge;
a partition wall which separates the cabin from the machine room and which has an opening through which the oil gauge is viewable from the cabin; and
a cover member sealing a gap between the partition wall and the oil gauge.

2. The work machine according to claim 1 ,
wherein the hydraulic oil tank includes an attachment portion to which an oil gauge is attached, and
wherein the cover member includes
a first peripheral member provided between the partition wall and the attachment portion, and
a second peripheral member protruding from the partition wall toward the cabin opposite to the first peripheral member.

3. The work machine according to claim 2 , wherein the first peripheral member includes
a cylinder part surrounding the oil gauge, and
an abutting part protruding from the cylinder part toward an outside of the oil gauge to abut the second peripheral member.

4. The work machine according to claim 2 , wherein the second peripheral member includes
a lock part configured to be locked onto an edge part forming the opening, and
a protrusion protruding from the lock part toward the cabin.

5. The work machine according to claim 4 , wherein the protrusion is inclined from the cabin toward the drive device room and toward the outside of the oil gauge.

6. The work machine according to claim 1 , wherein the oil gauge protrudes from the partition wall toward the cabin.

7. The work machine according to claim 1 , wherein the oil gauge is arranged at a position closer to the drive device room than the cover member.

8. The work machine according to claim 1 ,
wherein the hydraulic oil tank includes an attachment portion to which an oil gauge is attached,
wherein the hydraulic oil tank has a surface provided with the attachment portion, the surface facing the partition wall, and
wherein the cover member is provided between the partition wall and the surface.

9. The work machine according to claim 2 ,
wherein the cabin is rotatable with the partition wall and the second peripheral member with respect to the machine room, and
wherein the first peripheral member is configured to abut against the second peripheral member when the oil gauge is viewable from the cabin through the opening.
