ABSTRACT:
A steering shaft locking device capable of performing a locking operation in an optimum manner. The steering shaft locking device includes a motor to which voltage is applied to generate a drive force. A locking bar is moved by the drive force of an actuator so as to engage the steering shaft. A steering shaft lock ECU connected to the motor performs a first control to move the locking bar to a lock position, at which the locking bar engages the steering shaft, and a second control to move the locking bar to an unlock position, at which the locking bar is disengaged from the steering shaft. A voltage control means controls the voltage applied to the motor during the first control such that the voltage is less than or equal to the voltage applied to the motor during the second control.
