ABSTRACT:
A revolution detecting sensor includes a Hall IC facing a detection target, a magnet positioned behind the Hall IC and applying a bias magnetic field, and a substrate provided with a detecting circuit. The revolution detecting sensor is configured such that a lead terminal from the Hall IC bypasses the magnet, to be guided to the substrate. In a magnet holder holding the magnet, a recessed guide guiding the lead terminal is formed, and a pressing member is provided. Thus, a tip end portion of the lead terminal can be held in a prescribed position, and an operation for attachment to the substrate can easily be performed.
