Title:
VALVE TIMING CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2017/047254
Kind Code:
A1
Abstract:
In the present invention an angle sensor 35 is an electromagnetic induction sensor having a detected body 50, wherein a tubular base part 52a of a support part 52 is inserted into an insertion hole 14d of a motor output shaft 14. The angle sensor also is equipped with a detecting body, which is affixed to a cover member 4. When the tubular base part is inserted together with an oil seal 55 into the insertion hole to the maximum extent allowed by a flange part 54, the front edge of an outer circumferential portion 55a of the oil seal elastically contacts a stepped surface 21a of an annular groove 21 formed in the inner circumferential surface of the insertion hole, this elastic reaction force acts in the direction of the arrows F1 and F2, and the inside surface 54a of the flange part applies pressing force from the axial direction to front edge 14e of a small-diameter part. Accordingly, the rotational angle of the motor output shaft can be detected with high precision, and a stable secured state can be achieved after the detected body of a rotation detection mechanism is attached to the motor output shaft.
