<p><P>PROBLEM TO BE SOLVED: To provide a steering device which is suitably applied to an electric steering lock device and provided with a steering lock device capable of forming a large number of grooves or ridges to be engaged with a lock key. <P>SOLUTION: A key-lock collar 2 is constituted to include a square cylinder portion 21 on its body front side half and a cylindrical portion 22 on its body back side half. The circular outer circumference 26 of the cylindrical portion 22 has eleven ridges 27 formed at an angularly equal spacing to bulge radially outward. When an ignition key is turned to a lock position and pulled from the keyhole, a lock key 19 is protruded toward the axis of a steering shaft 13. As a result, the leading end of the lock key 19 comes into engagement between the side faces 271 and 271 of the adjoining ridges 27 and 27 of the key-lock collar 2 so that the steering shaft 13 is fixed with respect to a column 11, thereby blocking the rotation of the steering shaft 13. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
