<p>Provided is a differential gear device for a vehicle with which it is possible to prevent in an optimal manner an axle from separating from a side gear and to prevent a snap ring from coming off, even when an annular plate spring member is precompressed and interposed between the side gear and the differential case. With a disc spring (38), the section between an inner peripheral circle (42) and an outer peripheral circle (44) having the same center position is formed in a conical shape, and notches (46) are formed in three locations on portions of the outer peripheral circle (44), so the pair which comprise the symmetrical areas (48, 50), and which are symmetrical with respect to the center position and one of which includes a notch (46), have mutually different spring characteristics. Therefore, the inertial force of the rotational-axis (C1) direction reciprocating movement of side gears (20l, 20r) which are biased and rotated by means of disc spring (38) is suppressed, and the shock between the snap ring (34) and the side gears (20l, 20r) is alleviated, so it is possible to prevent in an optimal manner the axles (24l, 24r) from separating from the side gears (20l, 20r).</p> |
