Abstract: In a valve timing adjusting device, a second rotation body includes a second sun gear part provided inside of a first rotation body, and is connected to a drive shaft or a driven shaft through inside of the sprocket part to be rotated corresponding to the drive shaft or the driven shaft. When the second rotation body is brought into contact with the sprocket part, rotation of the second rotation body relative to the first rotation body is restricted. A planetary rotation body includes a first planetary gear part engaged with the first sun gear part, and a second planetary gear part engaged with the second sun gear part. The planetary rotation body makes a sun-and-planet motion inward of the first sun gear part and the second sun gear part to change a phase of the relative rotation between the first rotation body and the second rotation body.

Abstract: 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.
