る回転検出装置。 A rotating shaft is supported and held in a cylindrical outer case with an open front through a bearing, an inner case is fitted to this outer case, and the rotating shaft is integrated into the inner space formed by the outer case and the inner case. A magnet that rotates is disposed in the inner case, and a detecting section for detecting magnetic changes due to the rotation of the magnet is provided in the inner case, and the opening peripheral portion of the outer case is crimped to the outer circumferential surface of the inner case. In a rotation detection device in which a case and the inner case are fixed, the outer case and the inner case are formed of materials with different coefficients of thermal expansion, and both cases are elastically biased in opposite thrust directions. A rotation detection device characterized in that a resilient member is interposed between both cases.
