The present invention relates to a speed sensing device, a connector, an insert that is injection molded in a part of the connector and the rib is protruded on the outer circumferential surface during injection molding, and a detection element mounted to be connected to the connector to the insert and detecting a magnetic field change of the magnet; The magnet is fixed to the insert, provides a magnetic field to the detection element, and generates a magnetic field change by the relative rotational movement of the object, and injection molding is performed on parts other than the ribs of the magnet, the detection element, and the insert. Characterized in that it comprises a sealing portion formed. |
