Two electromagnetic coils are arranged in a fixed yoke made of a soft magnetic material whose longitudinal end face in a plane including the axis is formed into a substantially E shape so that the same polarity occurs in adjacent parts. A rare earth cobalt magnet magnetized in the axial direction is disposed in the hollow part of the fixed yoke, and magnetic pole pieces each having an annular part and a truncated conical part each having an outer shape substantially the same as that of the rare earth cobalt magnet are held at both ends of the rare earth cobalt magnet. The movable element is arranged so as to be movable in the axial direction. In the door lock actuator, the inner circumferential surfaces on both sides of the fixed yoke are formed to have a similar shape to the truncated conical portion of the magnetic pole piece, wherein the outer diameter of the fixed yoke is equal to or smaller than the outer diameter of the fixed yoke. The relationship between and the outer diameter dimension Dm of the rare earth cobalt magnet is 1.75
An actuator for a door lock, characterized in that ≦DoIDm≦12.1. 2. A utility model characterized in that a magnet of the R1CO5 system is used as the rare earth cobalt magnet, and the ratio of the outer diameter dimension Dm to the thickness dimension Lm of the magnet is 5.5≦D'm/Lm≦7.5. A door lock actuator according to registered claim 1. 3. A practical use characterized in that a magnet of the R2C0□7 system is used as the rare earth cobalt magnet, and the dimensional ratio of the outer diameter dimension Dm and the thickness dimension Lm of the magnet is 2.0≦Dm/Lm≦4.0. A door lock actuator according to claim 1. 4. The door lock actuator according to any one of claims 1 to 3 of the utility model registration claim, characterized in that the dimensional relationship between the fixed yoke and the movable element is determined as follows. A>B>C21g O<L B-C50 0≦1D-Al6 However, A: Axial distance between the end magnetic pole pieces of the fixed yoke B: Axial length of the central magnetic pole piece of the fixed yoke (,,) C: Inner axial distance between mover magnetic pole pieces (,,) D = Axial length of mover,,) L: Stroke (,,) 1g = Inner peripheral surface of fixed yoke Gap between the outer circumferential surface of the mover (,,).
