<p>An accelerator position sensor, which comprises a stationary member (1) fixed to a body of an automobile and a rotating member (2) biased rotatingly relative to the stationary member by torsion torque of a torsion coil spring (3) in a direction of return motion of an accelerator pedal, and which permits a sensor unit (4) to detect a rotating angle of the rotating member (2). In order to obtain adequate hysteresis in a pressing force characteristics of the accelerator pedal between a depressing motion and a returning motion, there is provided between a boss portion (1a) of the stationary member (1) and the torsion coil spring (3) a cylindrical-shaped resin member (6) which is pressed against the boss portion (1a) by a reaction force for the torsion torque of the torsion coil spring (3) to generate a sliding resistance between it and the boss portion (1a) when the rotating member (2) rotates.</p> |
