PROBLEM TO BE SOLVED: To provide a structure by which the circuit configuration can be formed simply regardless of case material of a main body and electric change- over be performed surely, in a clocking device in which an electric contact is cut off or changed over through operation of an external operating member. SOLUTION: A conductive material 20 incorporated along the inner circumferential surface of a shell is housed between its circomference and its intermediate frame 16A. While this state is kept, the end part of a band part 20c of the conductive material 20 is kept at ground potential when it is brought into contact with a ground spring 27 fitted to a movement. On the outer circumferential part of the intermediate frame 16A adjacent to the small width part 20b of the conductive material 20, a cut part 16b is formed oblique toward an opening which is formed in correspondence with the pressing part 22a, contact piece part 20a and movable part 24 of an operation button 22. |
