摘要： A rotational angle detecting sensor has a cylindrical housing including an end wall at a first end thereof. A covering member covers the second open end of the housing. A rotary shaft extends through the end wall of the housing and includes a large-diameter portion having a shoulder surface and rotatably received in the housing. A rotational angle detector is disposed between the inner surface of the covering member and the end surface of the large-diameter portion of the rotary shaft. An actuate groove is formed in the inner surface of the end wall of the housing concentrically with the rotary shaft. A stopper pin is attached to the shoulder surface of the large-diameter portion of the rotary shaft so as to be movable in the groove. The stopper pin abuts against the circumferential ends of the groove, thereby limiting the rotational range of the stopper pin.

摘要： An angle detection error is prevented by using a columnar permanent magnet that is radially double-pole-magnetized as a rotating angle detecting sensor while preventing a gap between a plurality of magnetic sensors and an end face of the permanent magnet from being narrowed. The permanent magnet is a ferrite magnet or an alnico magnet having a diameter of 4 mm to 20 mm, and an axial length of 3 mm to 5 mm. The plurality of magnetic sensors detects radial magnetic flux densities at positions axially spaced 0.5 mm to 3.0 mm apart from a central portion of the permanent magnet, the central portion having a diameter equal to or smaller than 20% of the magnet diameter to make it possible to perform detection in a range in which a distribution curve of a radial magnetic flux density has a moderate inclination.

摘要： In a rotation sensor unit, a lid 6 is pressed against a housing 2 to push an outer race 11 of a rolling bearing 1, thereby applying a preload to the bearing 1 and increasing the rigidity of the bearing 1, so as to prevent run-out of a shaft 3. An encoder 42 is supported on this shaft 3, and a magnetic sensor element 41 is supported on the lid 6, which is pressed against the housing 2. Thus, it is possible to prevent displacement of the magnetic sensor element 41 and the encoder 42 relative to each other. The shaft 3, lid 6 and outer race 11, etc. are made of a soft magnetic material to define a magnetically shielded space between one axial end surface of the shaft 3 and the lid 6, with the magnetic sensor element 41 mounted in the magnetically shielded space.

摘要： A one-way clutch unit includes a one-way clutch and an unlocking member. The one-way clutch includes inner and outer races. Two pockets having wedge spaces having a wedge angle are formed between the inner and outer races. Several rolling elements are received in each pocket. The unlocking member includes an annular portion concentric with the inner race, and axially extending unlocking pieces each received in one of the pockets between the end of the pocket that faces the narrow ends of the wedge spaces having the wedge angle and the rolling elements. By externally actuating the unlocking member, the rolling elements are moved toward the wide ends of the respective wedge space having the wedge angle, thereby unlocking the clutch. Thus, it is possible to unlock the clutch and prevent transmission of torque to the output member while the input member is rotating in the forward direction.

摘要： A rotation sensor unit includes an encoder, a holder radially positioning the encoder, and a rolling bearing having an inner race. The rolling bearing is fitted around the shaft so that one end of the inner diameter surface of the inner race protrudes from the end of the outer diameter surface of the shaft. The holder has a screwed portion fitted in the inner race, positioning the encoder coaxially with the shaft. The holder is non-magnetic, having a retaining portion in which the encoder is axially pressed. The encoder is a plastic magnet, with protrusions and recesses formed integrally on its outer diameter surface and biting the inner diameter surface of the retaining portion to prevent the encoder from rotating. With the holder screwed to the shaft, the encoder is disposed between the magnetism detection element and the one end of the shaft.
