Abstract

PURPOSE:To prevent the unconscious disengagement of a key and to prevent the unavailability by the suppression of a manual operating member, by providing a constitution wherein the key cannot be taken out unless the operation of the manual operating member is concurrently performed with the operation of the key by using both hands. CONSTITUTION:A rotor 6 and a key cylinder 3 are formed as a unitary body. An engaging pin 24 is provided in a small hole 33 in the surface of a flange 6a so that it is energized in the protruding direction by a spring 23. An arc shaped gruide groove 26, in which the tipe of the engaging pin 24 is inserted, is formed in the location corresponding to the part from a starting position to the position before the locking point in the key cylinder 3. The manual operating member 28, whose one end is protruded from the side of an ignition switch 11 and which can exclude the engaging pin 24 that is positioned at the corresponding point out of the guide groove 26, is slidably provided in a housing 1. In this constitution, the two step operation type steering lock having excellent safety can be performed.
