Claims

[Claims for Utility Model Registration] (1) A cylindrical boss portion is provided in the center of the inner surface of the circular end plate to protrude in the axial direction, and a cylindrical boss portion is provided in the outer periphery of the inner surface of the circular end plate in the axial direction. An annular outer circumferential wall is provided to protrude, and the inner hole of the cylindrical boss portion is fitted so as to be integrally rotatable with an extending end of a rotating shaft extending outward from the outer surface of the base body to which the rotation detecting device is attached. A rotating body configured to be fixedly attached, a detecting body disposed in a space between the cylindrical boss portion and an annular outer circumferential wall of the rotating body, and a detecting body detected by the detecting body. Either one of the objects to be detected is attached to the outer periphery of the cylindrical boss portion so as to be integrally rotatable, and the other one is
A rotation device configured such that it can be fixed to the base body via a bracket, and wherein the detecting body and the detected body are integrated into the rotating body in advance before fixing the rotating body to the rotating shaft. Detection device. (2) The rotation detection device according to claim 1, wherein the rotating body is a cam sprocket attached to a camshaft of a valve mechanism.
