摘要

PROBLEM TO BE SOLVED: To unitize a differential gear for rear wheels having a switching standby mechanism in the differential gear for rear wheels.;SOLUTION: The differential gear for rear wheels includes: a differential mechanism for rear wheels allowing the differential of left and right rear wheel axles 18; a dog-tooth type lock mechanism having a shift sleeve 20 and an engaged sleeve for switching between an unlock state in which the differential is allowed and a lock state in which the differential is prohibited; a casing 11 for housing the differential mechanism for rear wheels; a hand operation part for performing the switching operation of the lock mechanism; and a switching standby mechanism 30 for applying a biasing force to engage the shift sleeve 20 to the engaged sleeve and applying a biasing force to release the engagement of the engaged sleeve and the shift sleeve 20 when the switching operation is performed by the hand operation part. In the differential gear for rear wheels, the switching standby mechanism 30 is supported by the casing 11.;COPYRIGHT: (C)2011,JPO&INPIT
