PURPOSE:To reduce a degree of detection errors, by performing the support of a rotor by means of an arm inside a throttle valve opening detector at plural spots. CONSTITUTION:A rotor 2 is caulked to a base 1 together with a wave washer 2 by a bushing, and attached thereto free of rotation. An arm 3 is inserted into the bushing 6 and transmits motion of a throttle valve to the rotor 2. A connector 4 is caulked to the base 1, while a traveling contact 7 in this connector 4 slides on a cam groove 10 and comes on or off with a fixed contact 8. The rotor 2 is supported at two points of engaging parts 13 and 13' by the arm 3. With this constitution, from the arm 3, only such force as to rotate the rotor 2 operates thereon so that movements of the rotor 2 in a radial direction are brought to nothing, thus detecting accuracy is improved. |
