Abstract

PURPOSE: To release parking smoothly in an ascending or descending slope or the like by providing an oil pressure circuit to give forced releasing positively to the engagement between a ball member and a gear connected with an output shaft for releasing parking.
CONSTITUTION: For parking, when an unillustrated manual lever is displaced to shift a shift shaft 12 to the right, a cam 13 is caught by a roller 16 to rotate a ball member 14 around a pin 15 against a spring 19, and its tooth part 21 is engaged by a gear 22. Consequently, the rotation of an unillustrated output shaft is stopped for attaining parking. For releasing the parking at this stage, when a car is, for example, on a descending slope to give a one-sided force to the gear 22, a frictional force is given between the gear 22 and the tooth part 21 to prevent smooth releasing. Therefore, pressurized oil is supplied to a chamber 33 and conducted into a chamber 41 through a pipe line 31 for pulling up the member 14 forcedly by means of a piston 26 and a rod 27.
