PROBLEM TO BE SOLVED: To provide a protection device for a cylinder lock that includes a shutter plate acting between a closure position where a key hole of a cylinder lock is closed and an opening position where the key hold is opened, and a magnet lock with a rotor which can be rotated in unlocking and coupled to a shutter plate, and that prevents the shutter plate from rattling at the opening position and can decrease the number of components for imparting a feeling of moderation in operating the rotor.SOLUTION: A protection device includes an elastic member 57 having, in one body, a first contact part 57a which comes in elastic contact with a shutter plate 28 at an opening position and a second contact part 57b which comes into elastic contact with a rotor 40 when the shutter plate 28 is at a closure position so as to impart a feeling of moderation in rotating the rotor 40. |
