Claims

[Scope of utility model registration request]

A pole made of a ferromagnetic material, a bias magnet that supplies magnetic flux to this pole, a terminal that connects the terminal part of the detection coil and connects the external leader wire to the external leader wire fixed connection part, and the above detection coil is wound. The above-mentioned pole and bias magnet are successively superimposed and inserted and held, and the above-mentioned terminal is fixed, and the terminal has a pair of deformable protrusions near the external leader wire fixing connection part.
A bobbin having a U-shaped groove for holding the external lead wire between a pair of protrusions, and a bobbin that covers the detection coil including the terminal part and the bobbin, and deforms the protrusion when installed, and the outer part of the terminal. A rotation detection device equipped with a cap that comes into contact with the fixed connection part of the leader wire.
