摘要： An oil seal member is compressed between a connecting pipe for supplying oil to an oil chamber of a hydraulic servo and the cylinder drum of the hydraulic servo. The cylinder drum has an interior oil chamber and turns through a predetermined angle upon operation of a frictional engagement element by the hydraulic servo. The end of the seal member pressed against the cylindrical drum surrounds an oil hole 73 formed in the cylindrical drum, and oil pressure is supplied to the oil chamber through an oil passage in which the seal member is mounted and through the oil hole. A recess is formed in the outer surface of the cylindrical drum around the oil hole and the end of the seal member is received in the recess. When the cylindrical member turns within the predetermined angular range, the end of the seal member is protected by the recess. As a result, the end of the seal member is not damaged and the integrity of the seal is protected.
