摘要： In a valve timing control system of an internal combustion engine employing both an electric-motor-driven intake valve timing control device for changing intake valve timing and an electric-motor-driven exhaust valve timing control device for changing exhaust valve timing, the intake valve timing control device includes a less-friction roller speed reducer having a toothed gear and configured to transmit torque by repeated relocations of each of rollers rolling and relocating from one of two adjacent teeth of the toothed gear to the other. In contrast, the exhaust valve timing control device includes a planetary-gear speed reducer having a friction greater than a friction of the roller speed reducer and configured to transmit torque by meshed-engagement of toothed gears in mesh with each other.

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.
