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.

摘要： In an electrically-driven valve timing control apparatus employing a housing and a cover member axially opposed to each other, a cylindrical-hollow motor output shaft is installed in the housing, and configured to rotate relative to the housing by electricity-feeding to the electric motor, and also configured such that lubricating oil is supplied into the motor output shaft. A plug is fitted to the inner periphery of an axial opening end of the motor output shaft for suppressing a leakage of lubricating oil from the motor output shaft to the outside. One of two opposing faces of the cover member and the plug is formed with a protruding portion configured to prevent the plug's slipping out of the axial opening end. A part of the inside face of the cover member, opposed to the plug, is formed integral with the protruding portion partially disposed within the axial opening end.
