PROBLEM TO BE SOLVED: To provide an ESL which reduces unlock drive time as far as possible in order to shorten time from an operation of a start-push switch to a start of an engine.SOLUTION: The electric steering lock device comprises: a motor 15 that interlocks and moves a lock bolt 12; an ESL control portion 32 that controls a motor control relay 39 forming a power supply passage of the motor 15; lock bolt-position detecting means 41; an upper-level ECU 30 that transmits a lock-drive request signal or an unlock-drive request signal to the ESL control portion 32 and switches and operates the motor control relay 39; and power supply restricting circuit 40 provided in the power supply passage of the motor 15. The ESL control portion 32 is configured to respond to a detection signal to be output by the lock bolt-position detecting means when the lock bolt 12 is present at a lock position, switch and operate the motor control relay 39 before receiving the unlock drive request signal from the upper-level ECU 30, and conduct the power supply restricting circuit 40 immediately after receiving the unlock drive request signal. |
