転センサ。[Scope of Claim for Utility Model Registration] (1) A case body of a rotation sensor provided opposite to a sensor rotor formed in the shape of a gear in order to detect the rotational speed of a rotating body, and a molded body on the detection end inside the case body. A magnetoelectric transducer section is fixed by a member and outputs a change in a magnetic field as a change in an electric signal due to a change in electrical resistance, and a magnet is provided in conjunction with the magnetoelectric transducer section. A rotation sensor characterized in that a protection member is provided which has higher hardness than a mold member that comes into contact with and fixes the element and has electrical insulation properties. (2) The protective member shall have an outer circumferential surface formed with a diameter that joins to the inner circumferential surface of the case body, and an inner circumferential surface of which is formed in a cylindrical shape with a diameter that joins to the outer circumference of the magnetoelectric transducer section. The rotation sensor according to claim 1, characterized in that: (3) The rotation sensor according to claim 1 or 2, wherein the element of the magnetoelectric transducer section is a magnetoresistive element. (4) The rotation sensor according to claim 1 or 2, wherein the element of the magnetoelectric conversion element portion is a Hall element.
