摘要： A vehicle drive apparatus includes: a sleeve including a first peripheral surface provided side by side with a spline; a connecting member including a groove provided side by side with a spline in spline engagement with the spline, recessed radially relative to the first peripheral surface, and including a bottom surface that serves as a second peripheral surface facing the first peripheral surface; and a tolerance ring disposed in the groove so as to exert a radial elastic force between the sleeve and the connecting member.

摘要： A vehicle drive system including: a rotating electric machine; an output drivingly coupled to a wheel; a differential gear device provided in a power transmission path between the rotating electric machine and the output, the differential gear device including at least a first rotating element drivingly coupled to the rotating electric machine, a second rotating element drivingly coupled to the output, and a third rotating element that is selectively fixed by a one-way clutch to a non-rotating member and that is selectively fixed by a friction brake to the non-rotating member; and a clutch that selectively couples together two of the first rotating element, the second rotating element, and the third rotating element.
