Abstract

See full text

It includes: a housing (7) to which a torque is transmitted from a crankshaft; a vane rotor (8) mounted inside the housing and includes a cylindrical rotor (20) fastened to a camshaft (2) by a cam bolt (5); and a groove portion (47) formed at a distal end surface of a tubular part (23) of the rotor and has a lateral surface (47a) in a direction opposite to a direction of fastening of the cam bolt. The lateral surface includes an inside edge (47d) in a radial direction of the rotor, and is inclined in the direction opposite to the direction of fastening of the cam bolt, with respect to a first imaginary plane (S1) containing the inside edge and a rotational axis (O) of the vane rotor. This serves to suppress rotation of the vane rotor during bolting the vane rotor to the camshaft, and suppress deformation due to the suppression of rotation.
