The front axle 15 is made of a hollow pipe material with a substantially rectangular cross section, and substantially mountain-shaped front and rear boss plates 17a, 17b are attached to the center portions of the front and rear sides of the front axle 15, respectively. A substantially cylindrical swinging boss 18 is installed at the upper end, and a pivot 1 is installed in the boss 18.
4 is inserted so that the front axle 15 can freely swing around the pivot 14, and furthermore, a swing regulating member 20 made of an elastic material is connected to the lower surface of the chassis frame 1 located above the front axle 15. Moreover, the lower surface 20a of the member 20 is inclined in the shape of an inner bottom and outer height, so that the entire surface of the lower surface 20a comes into contact with the upper surface 15a of the front axle 15 when the front axle 15 is restricted from swinging. Front axle support structure for power working vehicles.

Claims

[Scope of utility model registration request]

A substantially U-shaped bracket 19 with a downward opening is provided in series on the front lower surface of the chassis frame 1, and a front-rear pivot shaft 14 is installed in the opening of the bracket 19. Approximately mountain-shaped front and rear boss plates 17a, 17b are attached to the center of the front and rear sides of the front axle 15, respectively, and approximately cylindrical rocking plates are attached to the upper ends of the boss plates 17a, 17b. A boss 18 is installed, and a pivot 1 is installed inside the boss 18.
4 is inserted so that the front wheel 15 can swing freely around the pivot shaft 14, and furthermore, a swing regulating member 20 made of an elastic material is connected to the lower surface of the chassis frame 1 located above the front axle 15. Moreover, the front axle support structure for a power working vehicle is such that the lower surface 20a of the member 20 is inclined such that the virtual extension surface of the lower surface 20a passes through the pivot shaft 14.
