A parking lock mechanism (100) comprises: a parking gear (102) disposed on a power transmission member (14) mechanically coupled to a drive wheel (36); and a parking pawl (150; 152; 154; 156; 158; 160) provided with a lock claw (114) configured to mesh with the parking gear (102) and switching between a lock state in which the lock claw is meshed with the parking gear and an unlock state in which meshing between the lock claw and the parking gear is released. In the mechanism, the lock claw (114) includes a first end surface (122) and a second end surface (120) opposite to each other in a face width direction, the lock claw (114) includes a tooth tip surface (128) provided with a retreated portion (128a; 128c) at a corner on the second end surface side, and a position (G) of a center of gravity of the parking pawl is on the second end surface side relative to a center plane (CP) in the face width direction of the lock claw.
