PROBLEM TO BE SOLVED: To ensure sufficient ground height with less number of parts while a differential device, a brake mechanism and a differential lock mechanism are built-in. SOLUTION: The differential device 64 is built-in in one of axle cases 63 supported by a traveling body 4, dividable to left and right parts and having the inside formed to a cylindrical hole 95a, and brake parts 63a are formed on outer ends of the left and right axle cases 63. A differential lock part 63b is formed at the inner side than the brake part 63a and final decelation cases supporting a driving wheel through an axle 68 are mounted to the outer ends of the left and right brake parts 63a. A differential yoke shaft 70 is penetrated from the differential device 64 into the left and right final decelation cases and a brake mechanism A is arranged between the differential yoke shaft 70 and the brake part 63a. A differential lock mechanism 177 is arranged between the differential yoke shaft 70 and the differential lock part 63b. COPYRIGHT: (C)2005,JPO&NCIPI
