<p>A concave surface (20b, 28b) is formed in at least one of a contact area of a parking lock pawl (16) with a cam (30), and a contact area of a sleeve (28) with the cam (30). The concave surface (20b, 28b) comes into contact with the cam (30) from one end portion to the other end portion in an advancing direction when the cam (30) is inserted between the parking lock pawl (16) and the sleeve (28). Therefore, it is possible to maintain contact surface pressure between the parking lock pawl (16) and the cam (30) low, thus restraining wear of the contact area favorably. This means that it is possible to provide a parking lock device for a vehicle (10), which restrains deterioration of durability.</p> |
