Document Type and Number:
WIPO Patent Application WO/2017/208530
Kind Code:
A1
Abstract:
The present invention is equipped with an electric motor 12 that causes a camshaft to rotate relative to a timing sprocket, and two slip rings 26, 27 formed one in front and one in back on the outer circumferential surface of a tubular part 17a of power supply plate 17 affixed to the front-end part of a motor housing. A connector retaining part 28 is provided on the upper end of the outer circumferential part of a cover member 4 provided so as to cover the front end of the power supply plate, and a pair of power supply brushes 39 and 40, which contact the slip rings from the radial direction, are provided on the connector retaining part. Thus, by changing the arrangement of the power supply brushes in the radial direction it is possible to reduce the axial length of the valve timing control device.
