PROBLEM TO BE SOLVED: To provide a parking mechanism of a speed change gear which can reduce noise due to operation, improve operability, and improve durability by suppressing a load for energizing each part to a low level while enabling sure engagement of a parking pole with a parking gear at parking lock.SOLUTION: When a parking pole (26) pressed by a cam body (23) abuts against a crest part (31a) of a parking gear (31), an auxiliary rotary gear (33) is pressed by a tip (22a) of a parking rod (22), whereby the parking gear (31) is rotated relatively to rotary bodies (35 and 37) against an energizing force of a second energizing member (38), so that the parking pole (26) is engaged with a trough part (31b) of the parking gear (31). As a result, a load (energizing force) of a first energizing member (25) energizing the cam body (23) can be set small in comparison with conventional parking mechanisms. |
