摘要： A parking control mechanism to prevent generation of noise and shock when a parking range is released after a vehicle has been parked so that a driver does not feel uncomfortable. A parking apparatus of an automatic transmission has a parking gear; a parking pole swingably disposed and provided with a claw arranged to selectively be engaged with a tooth space of the parking gear; an engagement inhibition device movably disposed and arranged to be moved to an inhibition position for inhibiting engagement between the claw and the tooth space and to an inhibition release position for releasing the inhibition of the engagement; and an engagement inhibition release device for moving the engagement inhibition device to the inhibition release position in synchronization with the rotation of the parking gear. After a residual torque existing between the parking gear and drive wheels has been released, the claw and the tooth space are engaged with each other.

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.
