Abstract
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.
