して成る回転検出装置。 The rotation detection device is interposed between an output shaft of a transmission and a flexible shaft for a speedometer connected to the output shaft, and outputs a pulse signal proportional to the rotation of the output shaft. One end of a rotating shaft rotatably supported via a bearing in a cylindrical casing made of a resin material is connected to the output shaft, and the other end is connected to the flexible shaft, and the rotating shaft is connected to the output shaft.
A ring-shaped magnet having a large number of N and S poles magnetized alternately in the circumferential direction is fixed to the casing, and a sensor storage part opening facing the magnetic pole surface of the magnet is provided in the casing. A magnetic sensor formed by resin-molding mounting components such as a resistive element is placed in close proximity to the magnetic pole surface of the magnet, a conductive coating is provided around the outer periphery of the magnetic sensor, and the coating is passed through the bearing. A rotation detection device comprising: a cover that is electrically connected to a rotating shaft, and the magnetic sensor is pressed and supported via a packing by a cover that is removably attached to an open end of the sensor storage portion.
