Abstract
A throttle opening degree detecting apparatus includes a resin gear, a permanent magnet, a yoke and a magnetic sensor. The resin gear is connected to a throttle shaft of a throttle valve and provided with a depressed boss portion in an axial position. The permanent magnet is mounted and secured along an inner peripheral surface of the boss portion in the resin gear without an adhesive. The yoke is mounted and secured along the inner peripheral surface of the boss portion in the resin gear without an adhesive. The magnetic sensor is arranged in a fixed side so as to oppose to the permanent magnet in a non-contact manner and outputs a signal indicating a rotation angle of the resin gear as an opening degree of the throttle valve. The resin gear is insert-molded with the yoke and the permanent magnet.
