Claims

[Scope of utility model registration request]

A sensor is provided adjacent to a rotating body on which a detected object is mounted at a predetermined position on the outer surface, and the sensor detects the position of the detected object by facing the detected object during one rotation of the rotating body. In an index signal detection device capable of detecting an index signal, a conductive pipe-shaped component having an inner diameter that allows the terminals to be loosely inserted into a pattern portion to which a plurality of terminals derived from the sensor and supporting the terminals are connected. are arranged substantially parallel to the tangential direction of the rotation locus of the rotating body in the vicinity of the sensor, and the terminals are inserted and fixed into each of these pipe-shaped parts.
