An electric steering lock device, comprising: an electric motor; an electric motor control circuit including: an operation relay for operating the electric motor, and a pair of rotating direction switching relays (RY1, RY2) for switching a rotating direction of the electric motor; and a locking rod that is displaced by driving of the electric motor, the locking rod being displaced between a lock position at which a steering shaft is locked to prevent rotation and an unlock position at which the steering shaft is unlocked to allow rotation, wherein: when the steering shaft is to be unlocked, the electric motor displaces the locking rod to the unlock position by energizing the operation relay in an ON status, and when the steering shaft is to be locked, the electric motor displaces the locking rod to the lock position by energizing the operation relay and the pair of switching relays (RY1, RY2) in an ON status respectively, and characterised by that it further comprises a control unit that, when the steering shaft is to be locked, outputs a first operation signal to the pair of switching relays (RY1, RY2) and that outputs a second operation signal to the operation relay after predetermined time has passed since the output of the first operation signal. an electric motor; an electric motor control circuit including: an operation relay for operating the electric motor, and a pair of rotating direction switching relays (RY1, RY2) for switching a rotating direction of the electric motor; and a locking rod that is displaced by driving of the electric motor, the locking rod being displaced between a lock position at which a steering shaft is locked to prevent rotation and an unlock position at which the steering shaft is unlocked to allow rotation, wherein: when the steering shaft is to be unlocked, the electric motor displaces the locking rod to the unlock position by energizing the operation relay in an ON status, and when the steering shaft is to be locked, the electric motor displaces the locking rod to the lock position by energizing the operation relay and the pair of switching relays (RY1, RY2) in an ON status respectively, and characterised by that it further comprises a control unit that, when the steering shaft is to be locked, outputs a first operation signal to the pair of switching relays (RY1, RY2) and that outputs a second operation signal to the operation relay after predetermined time has passed since the output of the first operation signal. an operation relay for operating the electric motor, and a pair of rotating direction switching relays (RY1, RY2) for switching a rotating direction of the electric motor; and a locking rod that is displaced by driving of the electric motor, the locking rod being displaced between a lock position at which a steering shaft is locked to prevent rotation and an unlock position at which the steering shaft is unlocked to allow rotation, wherein: when the steering shaft is to be unlocked, the electric motor displaces the locking rod to the unlock position by energizing the operation relay in an ON status, and when the steering shaft is to be locked, the electric motor displaces the locking rod to the lock position by energizing the operation relay and the pair of switching relays (RY1, RY2) in an ON status respectively, and characterised by that it further comprises a control unit that, when the steering shaft is to be locked, outputs a first operation signal to the pair of switching relays (RY1, RY2) and that outputs a second operation signal to the operation relay after predetermined time has passed since the output of the first operation signal. when the steering shaft is to be unlocked, the electric motor displaces the locking rod to the unlock position by energizing the operation relay in an ON status, and when the steering shaft is to be locked, the electric motor displaces the locking rod to the lock position by energizing the operation relay and the pair of switching relays (RY1, RY2) in an ON status respectively, and characterised by that it further comprises a control unit that, when the steering shaft is to be locked, outputs a first operation signal to the pair of switching relays (RY1, RY2) and that outputs a second operation signal to the operation relay after predetermined time has passed since the output of the first operation signal.
