PURPOSE:To enable to lock a differential gear system by one-action operation, by connecting a locking device through a Bowden wire with a locking lever. CONSTITUTION:Turning operation of a shift drum 28 against the bounce of a return spring 30 is performed by pulling a Bowden wire 33 through the turning operation of a locking lever 35 on a steering wheel 3 by an operator. Then, a pin 27 guided in a cam groove 29 together with a slider 23 is shifted to the left and a differential casing 17 and both side axle shafts 11 and 12 are unified by connecting a clutch cog 24 with a clutch cog 25 of the differential casing, that is, a differential gear system D can be kept under a locking state. Then, driving and tractive force can be improved by preventing rear wheel Wr from slipping at the time of running on the soft ground, such as the snowy ground. |
