Abstract
A carrier having short pinion gears and long pinion gears is made compact, and the mountability of the carrier on vehicles is improved. In a structure of the carrier, short pinion gear housing spaces are formed between thick-walled portions of a carrier body and a carrier cover, and long pinion gear housing spaces are formed between flange portions and the carrier cover. Bridge portions are provided on the radially outer side of the short pinion gear housing spaces, and fixed to the carrier cover. Openings are provided on the radially outer side of the long pinion gear housing spaces. Splines to be engaged with a friction member of a clutch are formed on the outer peripheral surfaces of the bridge portions.
