ABSTRACT:
In a parking mechanism of an automotive automatic transmission having a park gear, a parking pawl which can mesh with the park gear, a cam mounted on an actuator rod to change the position of the pawl and an actuator support fixed to the inside of a transmission case to slidably support the actuator rod, the actuator support is produced by press-forming of a sheet metal as a one-piece member whose middle portion is shaped so as to support and guide the actuator rod and the cam with the purpose of reducing production cost. The actuator support is easily fixed to the transmission case by forming two slits in the transmission case at the stage of casting the case and inserting two end portions of the actuator support respectively into these two slits each together with a leaf spring.
