Claim:
An electric steering lock device, comprising: a driving source; a rotator configured to rotate by a drive of the driving source in an unlock direction and in a lock direction, the rotator including a first cam member and a second cam member, the first cam member having a first detected part integrally formed on the first cam member to protrude from a side surface of the first cam member in a direction of a rotation axis of the first cam member; a lock member configured to follow the first cam member and shift between a lock position and an unlock position, the lock member being configured to prevent a rotation of a steering shaft at the lock position and allow a rotation of the steering shaft at the unlock position; a holding lever configured to follow the second cam member and oscillate between a standby position and a holding position, the holding lever being configured to allow a movement of the lock member at the standby position and prevent a movement of the lock member to the lock position at the holding position, the holding lever being configured to position at the standby position when the lock member positions at a position other than the unlock position and position at the holding position when the lock member positions at the unlock position; and a first position sensor and a separate second position sensor regarding the first detected part as a detecting target, both adapted to directly detect the first detected part, wherein, when the lock member positions at the lock position, the first position sensor outputs an ON signal and the second position sensor outputs an OFF signal, and wherein if the lock member positions at the lock position or at the unlock position is detected with detection outputs of the first position sensor and the second position sensor.
