Abstract

In the motor-driven steering lock device 10 , cam grooves 50 inclined relative to a circumferential direction of a cylindrical part 46 of a lock bolt 44 are formed on an outer circumferential surface of the cylindrical part 46 , a cylindrical rotator 26 that is driven to rotate by an electric motor 16 is provided, the cylindrical part 46 of the lock bolt 44 is disposed inside the rotator 26 so as to be movable in an axial direction of the rotator 26 , and cam followers 32 held in longitudinal grooves 30 of the rotator 26 are moved in the cam grooves 50 so as to move the lock bolt 44.

Description

technical field [0001] This application is based on Japanese Patent Application No. 2004-167425 and No. 2004-167427, the contents of which are incorporated by reference. Background technique [0002] The invention relates to a motor-driven steering locking device, which is used for locking the steering wheel of automobiles or similar vehicles. [0003] Conventionally, steering locking devices for anti-theft purposes are known for locking the steering wheel of a motor vehicle or the like. Generally, in the steering lock device, there are engagement grooves on the outer circumference of the steering shaft that rotates with the operation of the steering wheel. When the deadbolt enters the groove and engages with the engagement groove, the rotation of the steering shaft is restricted and the steering wheel is locked. On the other hand, when the deadbolt leaves and disengages from the engagement groove, the steering shaft can rotate and the steering wheel is unlocked. [0004]...
