Abstract
A differential gear for automotive vehicles comprising a washer interposed between the backs of pinions and the inner surface of a differential casing and fitted to a pinion shaft. The washer has at most a thickness of l tan.alpha. wherein l represents a displacement from an uncompressed condition of a spring washer to a compressed condition thereof exhibiting a predetermined pressure against the side gears. With this arrangement, the pinions may be installed into the differential casing without applying any pressure through the spring washers to the side gears, and after installation of the pinions into the differential casing, pressure between the meshed gear teeth of the side gears and the pinions may be desirably determined.
