PROBLEM TO BE SOLVED: To provide an electric steering lock device capable of increasing a pull-out force of a lock bolt and also shortening a pull-out time for the lock bolt.SOLUTION: An electric steering lock device 1 comprises: a rotary member 40 which can be rotated in regular and reverse directions with drive force of an electric motor 61; a screw mechanism including a male screw part 32a disposed on a lock unit 30 and a female screw part 40b disposed on the rotary member 40, which makes the lock unit 30 move toward a lock position or an unlock position according to the rotation of the rotary member 40; and a spring 80 for energizing the lock unit 30 toward the unlock position. Non-engaging parts 32g and 40c in which the screw mechanism is disengaged are disposed on the lock unit 30 and the rotary member 40, respectively, and in a disengaged state where the male screw part 32a and the female screw part 40b are disengaged from each other, the lock unit 30 can be moved toward the unlock position with energization force of the spring 80.SELECTED DRAWING: Figure 2 |
