Claims

[Scope of utility model registration request]

A magnet is attached to the rotating shaft side, a magnetic sensor such as a Hall IC or a Hall element is attached to the body side that rotatably supports the rotating shaft, and the rotating shaft is rotated by applying a magnetic flux change to the magnetic sensor with the magnet. In a rotation detector designed to detect the number of rotations, a resin magnet support part and a rotation support part are integrally formed on the rotation shaft, and the magnet is embedded and supported in the magnet support part, and the rotation A rotation detector characterized in that a support part is rotatably supported on the body side.
