PURPOSE:To enable a suitable material to be respectively selected for an outer cylinder and an inner cylinder, by engaging the outer cylinder, equipping a parking gear, with the inner cylinder by welding. CONSTITUTION:An annular cylinder 30 peripherally provides in its peripheral side part 31 a parking gear 31a and forms in the peripheral 321 an inner spline 32b for supporting a clutch C3 by spline fitting its clutch plate 32a and the periphery of a carrier cover 331 of a carrier P1. One end side 33a of an outer cylinder 32 treating surface hardening by quenching is externally fitted to an outside cylindrical part 33 of an internal cylinder 35, arranging a spring 37 between the press molded outside cylindrical part 33, line pressure supply oil path hole 34 of an oil hydraulic servo C-3 and a piston 3P and consisting of an inside cylindrical part 38 and a circular annular plate-shaped part 39, and a fitted surface 30A is welded by an electron beam. |
