Abstract:
To solve a problem that the attachment work of a detected member of a rotation detection mechanism to a motor output shaft has been difficult.SOLUTION: A detected member 50 of an angle sensor has: a support part 52 which is inserted into and held in a small-diameter part 14b of a motor output shaft 14; a flange part 54 arranged at an external peripheral face of a tip part of the support member at a cover member side; a protrusion 52b protruded frontward from the flange part of the support part; and a detected rotor 53 arranged at a tip face of the protrusion. A fixing member 60 has a circular plate part 61 having a through-hole 63 at a center, and a cylinder part 62 arranged at an external peripheral edge of the circular plate part so as to be protrusive in a motor output shaft direction. The fixing member also has an engagement groove 56 formed at an external peripheral face of the protrusion, and an extension part 64 arranged at a hole edge of the through-hole integrally therewith, and regulating the movement of the detected member in an axial direction in a state of being engaged with the engagement groove.SELECTED DRAWING: Figure 9
