Title:
VALVE TIMING CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/008211
Kind Code:
A1
Abstract:
A member 50 to be detected of an angle sensor has a support part 52 which is inserted and held in a small-diameter part 14b of a motor output shaft 14, a flange part 54 which is disposed on the outer periphery of a cover member-side tip part of the support part, a projection part 52b which projects forward from the flange part of the support part, and a rotor 53 to be detected which is disposed on the tip surface of the projection part. A fixation member 60 has a disc part 61 which has a through-hole 63 at the center thereof and a cylindrical part 62 which is disposed on the outer peripheral edge of the disc part so as to project in the direction of the motor output shaft. An engagement groove 56 is disposed on the outer peripheral surface of the projection part, and an extension part 64 is integrally disposed with the rim of the through-hole and engaged with the engagement groove, thereby restricting axial movement of the member to be detected. Consequently, the member to be detected of the rotation detection mechanism can be easily attached to the motor output shaft.
