Abstract
A valve timing control device comprising, a cam shaft assembled within an engine, a rotational transmitting member having a concave portion, which is mounted around the cam shaft to rotate relative thereto within a predetermined range for transmitting a rotational power from a crank pulley, vanes provided on the cam shaft, fluid chambers formed between the cam shaft and the concave portion, which are separated into advancing and delaying chambers by the vanes, a fluid supplying means for supplying fluid under pressure to a selected one of the advancing and delaying chambers, and a stopper located between a radially inner portion of a side wall of the concave portion and the vane to restrict rotate relative between the rotational transmitting member and the cam shaft.
