A differential gear apparatus comprises a differential gearing limiting mechanism and a differential gearing mechanism (2) including an input element (5) and an output element (8a), an output shaft (9a) spline-connected (S1 and S2) at an end of the output shaft to the output element (8a), and a differential gearing limiting mechanism (3) including a first (10) and a second differential gearing limiting element (11). The first differential gearing limiting element (10) is spline-connected (S3 and S4) to an intermediate portion of the output shaft (9a), and the second differential gearing limiting element (11) is spline-connected (S5 and S6) to the input element (5), both or either one of following two relationships is established: distances between a position of a tip end of a spline at an end of the output shaft and the tip end of splines of the second gearing limiting element (A) and the intermediate portion of the output shaft (C) are set larger than distances between a position of rear end of a spline of the output shaft and positions of splines of the input element (B) and the first differential gearing limiting element (D). This is to overcome disadvantages in assembling of the differential gear apparatus owing to the cocurrent rotation of the output shaft (9a) and the output element (8a). <IMAGE> |
