PROBLEM TO BE SOLVED: To store a mounting component in a space inside an outline shape of the mounting component while reducing a mounting space for mounting the resin-made mounting component to a resin-made case. SOLUTION: Fitting protrusions 15, 16 are protrudingly provided to an upper case while forming fitting holes in an operation button unit 7, which is the resin-made mounting component so as to assemble the operation button unit 7 to the upper case constituting the resin-made case. The operation button unit 7 is mounted to the upper case while fitting the fitting protrusions 15, 16 into the fitting holes after composing the fitting holes. One end side of each of belt-like pieces 11, 13 is implanted integrally to a unit case 9 at mounting sites 10, 10a of the operation button unit 7. Hole shapes 12, 14 are allowed to be elastically expandable while being separated from the mounting sites 10, 10a after forming the other end side of each of belt-like pieces 11, 13 at the hole shapes 12, 14.
