An angle detector which can suppress strange feeling of the user of vehicle during rotary operation of a member to be operated. The angle detector comprises a yoke (magnetic member)(4) with a magnet (magnetic member)(3) having a first gear (2) which rotates depending on the amount of operation of a throttle grip (a member to be operated)(1), a Hall IC (magnetic detection means)(5) for detecting variation in magnetic field strength incident to rotation of the yoke (4), a rotating body (rotating member)(7) having a second gear (6) which rotates as the first gear (2) rotates and rotating about a central axis of rotation different from that of the yoke (4), a case (frame)(9) having a cavity (8) for encasing the yoke (4), the Hall IC (5) and the rotating body (7), and a spiral spring (resilient member)(10) having one end secured to the rotating body (7) and the other end secured to the case (9) and urging the throttle grip (1) to the initial position wherein the first and second gears (2, 6) are helical gears.
