Abstract
PURPOSE: To hinder an illegal unlocking by making an inner cylinder rotatable such that a protection piece is put on a first accommodation part, the operation piece of a second accommodation part is allowed to cross over a boundary of the inner and outer cylinders, and a driver pin and an inner end of the operational piece are positioned at a boundary of both cylinders during key insertion. CONSTITUTION: A first accommodation part 15 is provided over a range from the inside of an inner cylinder 2 to the outer surface part thereof, and a second accommodation part 16 is provided at an outer cylinder 1 being communicated therewith; then a tough protection piece 17 having a slant surface 17a inclined with respect to a central axis 1 of the inner cylinder 2 is placed movably in an inside periphery of the first accommodation part 15. In addition, an operation piece 18 having an inner end of the second accommodation part 16 put in contact with the outside of the protection piece 17 is placed to be urged inward. Furthermore, the operation piece 18 being in contact with the protection piece 17 is positioned in a manner crossing over a boundary S of the outer cylinder 1 and inner cylinder 2, and a driver pin and an inner end part of the operation piece 18 are positioned at both cylinders 1, 2 in order for the inner cylinder 2 to be rotatable with respect to the outer cylinder 1. This constitution prevents the lock from being destroyed or picked.
