Abstract
A vane rotor, a bush, and a press-fitting member are connected with a camshaft of an engine. The bush is supported by an inner surface of a front plate of a shoe housing. The press-fitting member is contact with an end surface of the camshaft. The bush and the press-fitting member are respectively press-fitted into both end surfaces of the vane rotor. Due to a press-fitting force difference between the bush and the press-fitting member, the vane rotor is slightly warped in a press-fitting direction of the bush to rotatably slide on an inner surface of the front plate.
Claims7
A valve timing controller provided in a driving force transferring system that transfer a driving force of a driving shaft of an internal combustion engine to a driven shaft for opening/closing at least one of an intake valve and an exhaust valve, comprising:
- a housing rotating with one of the driving shaft and the driven shaft, the housing forming a chamber therein;
- a vane rotor rotating with the other one of the diving shaft and the driven shaft, the vane rotor having a vane that is accommodated in the chamber to divide the chamber into a retard chamber and an advance chamber, the vane rotor enabled to rotate in a retard direction and an advance direction relative to the housing by a pressure in the retard chamber and the advance chamber;
- a bush press-fitted into one end surface of the vane rotor in an axial direction, the bush supported by one axial sidewall of the housing;
- and
- a press-fitting member press-fitted into the other end surface of the vane rotor in the axial direction.
