Abstract:
A valve timing control device for an internal combustion engine includes: a driving rotation member; a driven rotation member fixed to a cam shaft; an electric motor; a speed reduction mechanism; a power feeding brush; and a power feeding plate which is provided to the driving rotation member, and which includes a slip ring on which the power feeding brush is abutted, the power feeding plate including a rigidity plate portion whose outer circumference portion is fixed to the driving rotation member, and a resin portion formed by molding an outer surface of the rigidity plate portion, and the rigidity plate portion including a holding hole which holds the power feeding brush through the resin portion, and being integrally formed with a reinforcement portion which is formed at a portion except for the holding hole, and which extends in a radially inward direction.
