Abstract
An influence of use orientation on detection accuracy is reduced. A magnetism detection device includes a magnet (Mr) magnetized, an angle sensor (Sr) as a magnetic sensor configured to detect a magnetic flux from the magnet (Mr), a magnet holder holding the magnet (Mr), and a second layshaft gear shaft. The magnet holder is rotatably supported on the second layshaft gear shaft. The second layshaft gear shaft is made of a magnetic material. An attractive force due to a magnetic force is generated between the magnet (Mr) and the second layshaft gear shaft in a direction of a rotation axis of the magnet holder.
