<p>PROBLEM TO BE SOLVED: To avoid an increase in size of a locking output lever in its operating direction by creating a theft-preventive (deadlock) condition and a locked condition from the same rotary movement from an initial stop position to a door locking position. SOLUTION: Once a rotor 3 driven for rotation by a motor 1 is put into rotational movement from an initial stop position to a locking position, the holder 43 of a output shaft restraint device 6 is given linear movement in the direction to approach an output shaft 4, so that the end of the holder 43 is held inserted in a fitting hole 21 provided in an actuation lever 7, thus restraining the output shaft 4. When the rotor 3 is again put into rotational movement from the initial stop position to the locking position, the holder 43 is released and given linear movement in the direction to move away from the output shaft 4, thus allowing the end of the holder 43 to move out of the fitting hole 21 to cancel the restraint of the output shaft 4.</p> |
