いては次の技術的手段を講じた。Conventional devices for adjusting the tread according to the width of the ridges, etc. are designed to connect the outer part of the front axle housing, which is fixed to the left and right sides of the front wheel differential case, and the inner part of the gear case, which supports the front wheel axle, interchangeably. The outer case is formed into an inner and outer case that is expandable and retractable, and a bottle inserted through the outer case is inserted into one of a plurality of bottle holes provided in the inner case, and a stay is interposed between the two cases. The inner and outer cases are fixed in their respective extendable and retractable positions, and the front wheel drive shafts housed in the front axle housing are formed so that they can only extend and retract. Since the above-mentioned inner and outer cases are located below the front chassis of the vehicle, the work of aligning the bin holes and the bins of both cases and removing and attaching the stays during the tread adjustment operation is as follows.
It is extremely troublesome since it is carried out in a narrow space. Therefore, in order to facilitate the tread adjustment operation, the following technical measures have been taken in this invention.

In the tread adjustment device in which the left and right position of the front axle housing (1) can be freely adjusted with respect to the front axle housing (1), the left and right position adjustment is performed with respect to the front axle housing (1).
) and a fixed side gear case (6) are removably connected to each other by a hydraulic cylinder mechanism (2). With this structure, the tread adjustment operation can be performed steplessly using the hydraulic cylinder mechanism (2), with extremely little manual effort (easy and
This means that the hydraulic cylinder mechanism (2) can be quickly installed in the front axle housing (1) and the stationary gear case (2), unlike the current front wheel drive system which does not have the hydraulic cylinder mechanism (2). 6), and by performing a simple modification work such as replacing the front wheel drive shaft (2) with one that can only be expanded and contracted, the system can be changed to an adjustable tread specification. With this invention, the inconvenience of having to perform the tread adjustment operation in a narrow space between the front chassis and the front axle housing, which is the case with the conventional device described above, can be overcome.
