To improve turnability to reduce steering force and to reduce the number of part items by composing a differential limiting device mounted between front right and left wheels of a device to distribute drive torque differently at a specified ratio when a difference between the revolutions of the right and left wheels occurs.
A front final assembly 21 is formed integrally with a ring gear 75a at a left cap section 74, forming a cap 75 with ring gear. A left output side cam 81 is arranged inside the cap 75 through a disc spring 85, a thrust washer 84 and a thrust bearing 83. A case body 73 is mounted on the cap 75 through bolts 85, and a plurality of input side blocks 77 and 78 are installed in the case body 73 in parallel with the periphery so as to come into contact with the left output side cam 81. In addition, a right output side cam 82 is arranged so as to come into contact with the input side blocks 77 and 78, and a right cap 76 is mounted on the case body 73 so as to be adjacent to the right output side cam 82. A differential case assembly (differential limiting device) 50 is thus constituted.
