発生装置。[Claims for Utility Model Registration] 1. A magnetic sensor with a lead wire is attached to a substrate provided along the rotation surface of a rotating body, and changes in the magnetic field based on the rotation of a magnetic pole section provided on the outer periphery of the rotating body are detected by the magnetic sensor. In the device that detects with a sensor and generates a signal synchronized with the rotation of the rotary body, the magnetic sensor is attached so that its lead wire runs along the substrate, and the magnetic sensor is mounted opposite to the magnetic pole portion. A rotation synchronization signal generating device characterized by stacking magnetic flux focusing members made of magnetic material. 2. The rotating body is made of a magnetic material, and a yoke is provided between the side of the magnetic sensor opposite to the magnetic flux concentrating member and the rotating body. The rotation synchronization signal generator according to item 1.
