Description

DETAILED DESCRIPTION OF THE INVENTION An example of a conventional mast support structure for a role vehicle is shown in FIG. 1.2.

In Fig. 1.2, the mass I is welded to the mass l-1 on the outer periphery of the housing 7 which houses the final reducer 8 in the mast for mass reduction. Zabotoso'Shigenoto 2

There was a problem in that the mass i-bot bracket 2 and the cap 5 abutted against the side wall 10 of the groove 9 of the housing 7, producing a metal tapping sound.

The present invention has been made to solve these conventional problems, and the contact surface between the housing and the bushing is made into a tapered shape. The object of the present invention is to solve the above-mentioned problems by forming two bushings and providing a stopper on the cargo handling mast to prevent the bushing from being pulled out.

Hereinafter, this invention will be explained based on the drawings.

In Fig. 3.4, reference numeral 20 is a front-stage mast that includes several examples of inner masts, makeup, etc. not shown, and this front-stage mast 20 includes a pair of outer masses 121 and a plurality of masts connecting these outer masses 1-21. l” Subi A 22

- It is composed of a racket 23 and a cap 19 which is fixed to the mast support bracket 23 by bolts 17 via a bolt 18. This housing 27 is fixed to the solem 50 of the vehicle body via the active part fJ424.Final reduction (currently 25 is connected to Aqua, /I, shirt l-29, and the axle The outer end of the shaft 29 has a fat, aluminum-shaped drive 2 ().

As explained above, there is a housing that is fixed to the vehicle body and houses the final reduction gear, a TIIR mast that is rotatably supported by the housing, and a 7-stroke cargo handling pigeon that is disposed between the housing and the 7-stroke cargo handling pigeon. The contact surface between the housing and the bushing is formed into a tapered shape, and a stopper is provided to prevent the bushing from being pulled out.
