  • Valve timing control device for internal combustion engine
    Patent number: 10240494
    Abstract: Lock pin (71) is disposed movably in axial direction in accommodation hole (70) formed at vane rotor (12). Top end portion of lock pin (71) is fitted into lock hole (23) provided at housing (11), then relative rotation position of vane rotor (12) is restrained at predetermined lock position. Vane rotor (12) is provided with small diameter portion (84) and large diameter portion (85) which are formed alternately in circumferential direction. Large diameter portion (85) extends in circumferential direction so as to cover lock hole (23). First vane (36A) protrudes from outer periphery of large diameter portion (85) to radially outer side. At least a part of lock pin (71) and at least a part of accommodation hole (70) overlap with large diameter portion (85), and are located at position that overlaps with area (86) formed by elongating first vane (36A) to radially inner side.
