<p><P>PROBLEM TO BE SOLVED: To prevent a malfeasant key release by the pulling-out of a rotator without adding a part. <P>SOLUTION: In a device 1, a cylinder lock 5, the rotator 7 and a lock member 8 are housed in a casing body 2, a lock lever 23 is engaged with a projecting section 7b for controlling the rotation of the rotator 7 under a locked state and a rotation to the unlocking-operation place side of the rotator 7 is prevented. In the device 1, the lock lever 23 is changed to a disengaging place when a first operation is conducted under a proper state, and the rotator 7 is rotated from a lock-operation place to a unlocking-operation place when the cylinder lock 5 as a second operation is turned and operated. In the device 1, the lock member 8 is changed from a locked place to the unlocked place by a cam section for the rotator 7. In such a device 1, a reverse-rotation preventive projecting section 13 preventing the reverse rotation of the rotator 7 positioned at the lock-operation place is mounted near the cam section for the rotator 7, and a pulling-out preventive wall 32 preventing the pulling-out of the rotator 7 is fitted at the lock-operation place in a unit housing 23 for a solenoid unit 22. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
