ABSTRACT:
An angle detecting device including a magnetism gap where a magnetic-flux shutter rotates synchronously with a detection subject, a magnetic flux generator provided at one side of the gap, a magnetic-flux detector provided at the other side of the gap, an outlet of the signals from the detector, a frame integrally including the above-described generator, detector and outlet, and anchoring portions mechanically fixing the detector in a housing portion of the frame. In one embodiment, the anchoring portions are a pair of saw-toothed tabs formed by cutting and bending out a section of the plate. The saw-toothed tabs cut into the inner wall of the housing when the detector is inserted. In another embodiment, the anchoring portions are a pair of supporting tabs formed by bending extensions of the plate. The supporting tabs are clamped between a lower surface of the housing and a cover. In still another embodiment, a pair of coupling tabs provided with holes are formed integrally on the plate, and a pair of projections are integrally resin-molded in the housing portion of the frame. The projections passed through the holes are caulked when the detector is inserted.
