Abstract

A driving force transmitting apparatus includes a rotating shaft, a frictional engagement device, a piston member, a piston housing, a piston chamber, an oil pressure sensor, an attachment hole, an operating-oil receiving chamber, a bubble removing chamber, and a bubble discharging groove. The rotating shaft has an axial direction and is rotatable around the axial direction. The frictional engagement device includes a frictional engagement unit which is disposed around the rotating shaft and which includes first and second friction members that are alternately stacked in the axial direction. The piston member is movable in the axial direction to press the frictional engagement unit so that the first and second friction members are engaged with each other. The piston housing contains the piston member. The piston chamber is defined between an inner surface of the piston housing and the piston member.
