An electrically-operated steering lock device is capable of unlocking a steering shaft even when steering wheel torque is applied to the steering shaft. The electrically-operated steering lock device comprises a lock bolt structure for locking the steering shaft. The lock bolt structure is composed of a first lock bolt which is pivotably held on one radial side in a neighborhood of the steering shaft and which has a protruding piece to be engaged on its inner peripheral side with a receiving portion of the steering shaft, and a second lock bolt which is pivotably held on another radial side in the neighborhood of the steering shaft. The second lock bolt is rotatable to a protruding position and a retreat position along with the first lock bolt, and has a protruding piece to be engaged on its inner peripheral side with the receiving portion of the steering shaft. The protruding pieces of the lock bolts are each moved in a direction away from respective engaging surfaces of the receiving portion of the steering shaft when engagement is to be released.
