Abstract
A rotary element engaging device of an automatic transmission includes a stationary member, a planetary gear set having rotary elements, a frictionally engaging element interposed between the stationary member and one of the rotary elements, a one-way clutch interposed between the stationary member and the one rotary element, and an operating member for engaging and disengaging the frictionally engaging element. The rotary element is adapted to be selectively engaged with the stationary member through two paths formed of the frictionally engaging element and the one-way clutch. The one-way clutch is disposed between the frictionally engaging element and the operating member. The one-way clutch includes an inner race connected to the one rotary element and an outer race fixed to the stationary member. The operating member is adapted to act on the frictionally engaging element through the outer race.
