Abstract
A torque-transmitting device is advantageously applied to a secondary air control valve mounted on an automotive vehicle. The device includes a gear train for reducing a rotational speed of a motor and a mechanism for converting a rotational motion to a linear motion of a valve shaft. The gear train includes a final gear coupled to the valve shaft, and the final gear includes a flange positioned at an axial end of an axis of the final gear. A coil spring for biasing the final gear toward a predetermined position is disposed next to the flange and around the axis of the final gear. Slits or holes are formed through the flange, so that holding jigs for holding the coil spring are inserted, in an assembling process, into a cylindrical space between an inner circumference of the coil spring and the axis of the final gear.
