Abstract:
1. A valve timing control apparatus comprising: a driving side rotational member synchronously rotatable with a crankshaft of an internal combustion engine; a driven side rotational member provided coaxially with the driving side rotational member, the driven side rotational member being fixed to a camshaft of the internal combustion engine at a first side thereof in an axial direction, and being formed with a plurality of recessed portions into which a supporting jig is insertable at a second side thereof in the axial direction; a fluid pressure chamber formed at at least one of the driving side rotational member and the driven side rotational member; a vane separating the fluid pressure chamber into an advanced angle chamber and a retarded angle chamber; a lock member restraining a displacement of a relative rotational phase between the driving side rotational member and the driven side rotational member at a predetermined lock phase; and a cover plate fixed to a side of the driving side rotational member in an axial direction, the cover plate being formed with a plurality of through holes, through which the supporting jig is insertable, at a position in which each of the plurality of through holes is overlapped with each of the plurality of recessed portions of the driven side rotational member in a condition where the relative rotational phase is restrained at the lock phase.
