Steering lock device of automobile

Abstract

Abstract PURPOSE:To prevent a steering wheel from being locked in running operation, by arranging a key turnable to a lock position only when a car speed sensor, operated at car stop time, and an angular position sensor, detecting turning movement of the key, are both operated. CONSTITUTION:A longitudinally moving lever 10, limiting turning movement of a key 4 to its lock position, of a solenoid 9 mounted to a housing main unit 1, is always protruded in the main unit 1 and moved backward only when the solenoid 9 is electrically conducted. While an angular position sensor switch 12, provided to the main unit 1, is turned on by the turning movement of the key 4 to its lock position, to electrically flow a current in the solenoid 9. That is, a protrusion 15 of an interlocking member 14 to the key 4 is engaged to the longitudinally moving lever 10 at its protruding to stop the key 4 unmovable to its lock position, and an expanded part 16 turns on the switch 12 through a pin 13 at prescribed turning movement of the key 4. Here the solenoid 9 is connected in series to the switch 12 and sensor 17, and lock operation can be permitted only when the key 4 is turned at car stop time.
