PROBLEM TO BE SOLVED: To more reliably prevent the breakage of a supporting shaft and a fitting part by more reliably suppressing the inclination or the like of an operation button when mounting the supporting shaft on the operation button having a disc part and a cylindrical part.SOLUTION: An operation device 1 includes a cylindrical guide member 2, an operation button 4 arranged on the inner periphery of the guide member 2, and an operation mechanism 5 having a supporting shaft 51 for supporting the operation button 4. The operation button 4 is mounted on the supporting shaft 51 with the supporting shaft 51 fitted to a fitting part 43 of the operation button 4. The operation button 4 has a disc part 41, and a cylindrical part 42 linked to the back face of the disc part 41 and having an outer diameter smaller than the outer diameter of the disc part 41. The disc part 41 is movable along the inner periphery on one end side of the guide member 2, and the cylindrical part 42 is movable along the inner periphery of a protruded part 24 of the guide member 2. In the state that the operation button 4 is inserted into the guide member 2 and the front end of the supporting shaft 51 is not fitted to the fitting part 43, the cylindrical part 42 is arranged on the inner periphery of the protruded part 24. |
