Claims

[Claims for Utility Model Registration] A piston housing is disposed around the outer periphery of a rotating shaft rotatably disposed within a casing, and a piston is slidably held in the piston housing. A transmission clutch interposed in a power transmission path between the rotating shaft and other members is engaged or engaged in response to the displacement of the piston as pressure oil is supplied to and discharged from an oil chamber defined by the piston. In the automatic transmission for a vehicle, the piston housing extends in the radial direction of the rotating shaft, and has one end opening into the oil chamber and the other end opening onto a radial outer circumferential surface of the piston housing. An automatic transmission for a vehicle, characterized in that at least an opening for discharging pressure oil is formed, and the casing has an oil passage connected to the opening.
