摘要： A hydraulic engagement device includes a first friction engagement element, a second friction engagement element, a cylinder, a piston, an oil chamber, hydraulic oil, and a release groove. The first friction engagement element and the second friction engagement element are to rotate around a third rotational axis. The piston is slidably provided in the cylinder. The oil chamber is defined between the piston and the cylinder. The hydraulic oil is supplied to the oil chamber to move the piston to push the first friction engagement element or the second friction engagement element so that the first friction engagement element engages the second friction engagement element. The release groove is provided on the cylinder or the piston. The hydraulic oil in the oil chamber is released through the release groove when a stroke of the piston exceeds a predetermined level.

摘要： A power transmission system includes a rotating shaft, a power transmission component, a pressing member, and a wave spring. The rotating shaft is rotatable about a rotating axis. The power transmission component includes a frictional engagement portion that includes a plurality of friction members alternately stacked in an axial direction along the rotating axis. The pressing member has a contact portion and is disposed to be movable in the axial direction to press the frictional engagement portion such that the plurality of friction members engage with each other. The wave spring is to press the pressing member at the contact portion in the axial direction away from the frictional engagement portion. The contact portion of the pressing member has a reduced friction between the contact portion and the wave spring along a circumference of the wave spring.
