Provided is a valve timing control apparatus that allows relaxation of manufacturing precision of a driving-side rotary member and a driven-side rotary member and that achieves space saving at the same time. An urging member includes at least one trough-folded portion and at least one crest-folded portion, one end side contact portion formed between one terminal end of the urging member and the trough-folded portion and coming into contact with a sealing element, and other end side contact portion formed between the other terminal end of the urging member and the crest-folded portion and coming into contact with a partitioning portion. In association with urging of the urging member, the distance between the one end side contact portion and the other end side contact portion along the urging direction is decreased and the angles of the trough-folded portion and the crest-folded portion are decreased.
