DIFFERENTIAL GEAR FOR VEHICLE AND VEHICLE

摘要

A diff case is attached to a side face of a ring gear wheel on the opposite side to the side on which the ring gear wheel and a pinion gear wheel mesh with each other. The ring gear wheel integrally has a boss portion, in which a driven shaft is fitted, on the meshing side with the pinion gear wheel. An annular member slidably movable in an axial direction thereof is provided on the boss portion with a guide portion for guiding the annular member. A lock pin is provided on the annular member for inserting into pin holes formed in the ring gear wheel and a left output side cam to place the differential mechanism into a locked state. A sliding region within which the annular member slidably moves is disposed so as to be included in a projection region of the diameter of the pinion gear wheel
