て従系している。In order to make it easier to get on and off the tractor, and to improve livability by creating a wide space up to the ceiling in the cabin, a flat floor plate is provided above the transmission case to accommodate the change lever. The applicant has proposed a speed change operation mechanism that does not protrude upward from the transmission case, but protrudes outward from one of the left and right side walls.
No. 0, /1. It is subordinate to FF Application No. 57-091095.

まうと云う不利がある。In order to make the upper surface of the transmission case as low as possible, the shifter stay of the shift part is placed near the inside of the side wall of the transmission case, but since it is a multi-stage transmission mechanism including reverse In this case, the numerous retaining arms attached to the shifter stay are concentrated near the upper part of the ITQ wall, and for this reason, the upper part of the side wall of the transmission case is formed to bulge outward. This has the disadvantage that the horizontal width of the transmission case becomes wider.

まま小形化ができるよう（ニ工夫したものである。Therefore, in this invention, the ceiling Bit is arranged in the horizontal direction by penetrating the horizontal side wall of the mission case which is formed into a roughly flat plate shape.
Two shifter stays on one side are arranged in the upper part (two upper and lower turns and parallel to each other) at the upper part of any one of the above walls, and on the upper part of the inside of the other side wall. 1. Others

To prevent a certain jitter from being engaged with the shift part of each transmission) and 1, the outside of the transmission case (III) (two-pronged CJ gear change lever) should be connected to the above (I'ψ) engaging arm of the operating shaft. The space near the left and right inner corners between the ceiling of the transmission case and the ll1l wall is constructed so that the shift part can be engaged and disengaged, and the shift part is operated by the change lever at this locked position if'71m. It was designed so that the transmission case could be made smaller while keeping the width of the transmission case narrow.
