PROBLEM TO BE SOLVED: To provide an effect for restraining theft and simplify a structure to easily apply it to an existing switch, by substantially blocking a key hole of a first cylinder lock using a second cylinder lock. SOLUTION: At a time of parking of a motorcycle, by operating a second cylinder lock 11 with a lock key 6 into a lock state, a key hole 12 of a rotor 10 can be substantially blocked by the cylinder 13 or the like and insertion of foreign matters into the key hole 12 by a third party can be restrained. Because the key hole 12 of the rotor 10 is covered by the cylinder 13 or the like and only a part of the longitudinal central part is visually recognized from outside, a third party can be notified at a glance that insertion of foreign matters into the key hole 12 is difficult, and restraining effect to theft of a vehicle can be provided. By partly charging the shape of the rotor 10, a body cap 3 or the like, the switch can easily respond to an existing switch. |
