Claims

[Scope of utility model registration request]

A key rotor is provided on the cylinder body and is rotated between a plurality of unlocking positions and a single locking position by inserting a key, and is moved in the axial direction by pressing the key, and a steering wheel is rotated by the key rotor. a lock cam that controls a lock member for locking and unlocking by its rotation; a protrusion provided on either the inner periphery of the cylinder body or the outer periphery of the key rotor; A first key provided on the other of the inner periphery or the outer periphery of the key rotor and adjacent to the lock position when the key rotor is rotated from the unlock position to the lock position without being pressed.
At the first unlock position, the key rotor engages with the convex part to restrict the rotation of the key rotor, and when the key rotor is pushed in at the first unlock position, the key rotor is disengaged from the convex part and the key rotor is moved to the first unlock position. A first restricting protrusion that allows rotation to the lock position, and a second regulating protrusion provided on the other of the inner periphery of the cylinder body or the outer periphery of the key rotor so as to face the protrusion, and that allows the key to be rotated to the unlocked position. a second regulating protrusion that engages with the protrusion and prevents rotation of the key rotor when the key rotor attempts to rotate toward the first unlock position in a pushed-in state; Device.
