Abstract

A front fender includes: a first member, at least a part of which is disposed upward with respect to a front tire of a wheel loader; a second member which includes an upper plate having an upper surface facing a lower surface of the first member, and a rear plate which is connected to a rear end of the upper plate and disposed rearward with respect to the front tire; an inclined plate which is connected to a lower surface of the upper plate and a front surface of the rear plate; and a connecting member which connects the upper plate and the first member. The inclined plate includes: a through hole which is provided immediately below the connecting member and through which the connecting member can pass; and a notch hole which is provided at a lower end of the inclined plate.

First claim

The invention claimed is:

1. A front fender comprising:
a first member, at least a part of which is disposed upward with respect to a front tire of a wheel loader;
a second member which includes an upper plate having an upper surface facing a lower surface of the first member, and a rear plate which is connected to a rear end of the upper plate and disposed rearward with respect to the front tire;
an inclined plate which is connected to a lower surface of the upper plate and a front surface of the rear plate; and
a connecting member which connects the upper plate and the first member, wherein
the inclined plate includes a through hole which is provided immediately below the connecting member and through which the connecting member passes, and a notch hole which is provided at a lower end of the inclined plate.

2. The front fender according to claim 1 , wherein the notch hole is provided at a position different from a center of the inclined plate in a vehicle width direction parallel to an axle of the front tire.

3. The front fender according to claim 1 , wherein
the lower surface of the first member includes a first lower surface which is in contact with the upper surface of the upper plate, and a second lower surface which faces the upper surface of the upper plate while being spaced from the upper surface, and
in the first member, a first portion having the first lower surface is thicker than a second portion having the second lower surface.

4. The front fender according to claim 3 , wherein a plurality of the first lower surfaces is provided at intervals in the vehicle width direction parallel to the axle of the front tire.

5. The front fender according to claim 3 , wherein the first member includes a first female screw hole which is provided on the first lower surface and connected with a male screw of the connecting member.

6. The front fender according to claim 1 , wherein the first member includes a second female screw hole which is provided on an upper surface of the first member and connected with a male screw of a hoisting attachment.

7. A wheel loader comprising a vehicle body frame to which the front fender according to claim 1 is mounted.

8. The wheel loader according to claim 7 , comprising a positioning member which is fixed to the vehicle body frame and is in contact with a rear portion of the first member to position the first member.
