A parking lock mechanism (46) comprises a parking gear (48) integrally disposed on a rotating member (14) mechanically coupled to a drive wheel (36); a plate-shaped parking pawl (52) provided with a lock claw (50) configured to mesh with the parking gear and pivoted for switching between a lock state in which the lock claw is meshed with the parking gear and a non-lock state in which meshing between the lock claw (50) and the parking gear is released; and a cam mechanism (56) including a cam (54) in contact with the parking pawl (52) and moving the cam (54) in parallel with a rotation axis (CL) of the parking gear to pivot the parking pawl (52), the parking pawl (52) having a plate thickness made larger in a portion provided with the lock claw (50) as compared to the other portions of the parking pawl (52). The portion provided with the lock claw (50) of the parking pawl (52) has a surface that is formed on the front side in a movement direction of the cam (54) at the time of switching from the non-lock state to the lock state and that bulges in the movement direction.
