Abstract

A work vehicle includes an openable and closable bonnet that covers an engine and is rockable with respect to a body frame, a pin that is provided on the body frame side, and a lock that is provided on the bonnet side and is switchable between a locked state in which the bonnet is locked by the lock engaging with the pin and an unlocked state in which the bonnet is not locked by the lock not engaging with the pin.

First claim

What is claimed is:

1. A work vehicle comprising:
an openable and closable bonnet that covers an engine and is rockable with respect to a body frame;
an engaged portion that is provided on a body frame side; and
a lock that is provided on a bonnet side and is switchable between a locked state in which the bonnet is locked by the lock engaging with the engaged portion and an unlocked state in which the bonnet is not locked by the lock not engaging with the engaged portion; wherein
the lock includes:
a moving member that can move by being pressed by an operating tool; and
a lock portion that engages with the engaged portion, and is disengaged from the engaged portion as the moving member moves; and

the moving member includes:
a pressed portion to be pressed by the operating tool when inserted into a through hole of the bonnet; and
a guide portion having a cylindrical shape to guide the operating tool to the pressed portion by an inner wall of the cylindrical shape, and the guide portion is movable together with the pressed portion.

2. The work vehicle according to claim 1 , wherein the moving member includes:
a contact portion that comes into contact with the lock portion; wherein
the moving member rocks around a rocking shaft by the pressed portion being pressed by the operating tool, and presses the lock portion by the contact portion, and the lock portion is movable; and
a distance between the rocking shaft and the contact portion is shorter than a distance between the rocking shaft and the pressed portion when viewed from an axial direction of the rocking shaft.

3. The work vehicle according to claim 2 , wherein the pressed portion, the rocking shaft, and the contact portion are positioned substantially in a front-rear direction.

4. The work vehicle according to claim 3 , wherein
the lock is in a front portion of the bonnet; and
the moving member is forward of the lock portion.

5. The work vehicle according to claim 4 , wherein the moving member is bent so as not to interfere with a frame provided on an inner surface of the bonnet.

6. The work vehicle according to claim 3 , wherein the moving member is bent so as not to interfere with a frame provided on an inner surface of the bonnet.

7. The work vehicle according to claim 2 , wherein the moving member is bent so as not to interfere with a frame provided on an inner surface of the bonnet.

8. The work vehicle according to claim 2 , wherein the through hole is visible from a front of a vehicle body.

9. The work vehicle according to claim 1 , wherein the moving member is bent so as not to interfere with a frame provided on an inner surface of the bonnet.
