摘要： A valve-timing control apparatus varies a relative phase between a cam shaft and a crankshaft by energizing an electric motor through a power-feeding brush provided to be in contact with a slip ring. The valve-timing control apparatus includes a retaining member slidably retaining the power-feeding brush; a connector provided in the retaining member and connected to a power source; a pigtail harness including one end portion connected with the power-feeding brush, and another end portion connected with a terminal of the connector through a fixing portion; and a guide portion provided in the retaining member and including an outer circumferential surface formed in an arc-shape. The pigtail harness bends along the outer circumferential surface of the guide portion. The another end portion extends substantially in a linear arrangement from the fixing portion to a bending portion at which the pigtail harness bends along the outer circumferential surface.
