VEHICULAR ELECTRIC LOCK DEVICE

摘要

A vehicular electric lock device is provided in which a magnet is provided in a slider which is operated linearly in response to rotation of an electric motor and is operatively linked to a lock member, and a magnetic sensor detects by means of a magnetic field of the magnet that the lock member is in at least one of a lock position and a unlock position, wherein the slider (18) comprises a screw-fitting member (50) that is formed from a ferromagnetic material having rigidity and has a threaded shaft (17) screwed thereinto and a magnet retaining member (51) that is formed from a paramagnetic material, covers the screw-fitting member (50) and retains the magnet (19), and the magnet retaining member (51) is coupled to the screw-fitting member (50) while making impossible relative movement in the direction along an axis of the threaded shaft (17) and relative rotation around the axis of the threaded shaft (17). This enables the size to be reduced and the position of a lock member to be accurately detected.
