Claims

[Claims for Utility Model Registration] 1. In an actuator for a device that automatically locks and unlocks a door using an electrical operation switch, a yoke in which the i-section end face in a plane including the shaft is formed into a substantially E shape, Two electromagnetic coils are arranged via a coil bobbin so that the same polarity occurs in adjacent parts, and a permanent magnet magnetized in the axial direction is placed in the center of the yoke and a pair of magnetic pole pieces are attached to both ends of the permanent magnet. An actuator for a door lock, characterized in that a movable element having a movable element is mounted so as to be movable in an axial direction, and is provided with a reciprocating drive means having a dimensional relationship between the yoke and the movable element determined as follows. 5≦To♀≦, 8 (cap 3) Magnetic pole pieces consisting of an annular portion and a truncated conical portion having an outer diameter larger than the outer diameter of the permanent magnet are attached to both ends of an annular permanent magnet magnetized in the axial direction. The door according to claim 1, characterized in that the inner circumferential surfaces on both sides of the yoke are formed in a shape substantially similar to the truncated conical portion of the magnetic pole piece. Locking actuator.4 Utility model registration claim No. 3 characterized in that the taper angle of the truncated conical portion is pronated in the range of 5° to 25°.
Door lock actuator as described in section.
