PROBLEM TO BE SOLVED: To provide a push-button assembly structure capable of freely setting arrangement of a push-button, without being restrained by the height position of a board surface for mounting a switch and lessening backlash generated with motions of the push-button and attaining a structure suitable for assembling. SOLUTION: In the push-button assembly structure, a cylindrical section 12a arranged on a case lower plate 12 and a rib 12b arranged on a case upper plate 11 are arranged by sandwiching an opening 13a of a case side plate 13, a push-button member 40 includes a pair of projection pieces 43, respectively extending in opposite directions from a right and left direction facing a switch pushing-down face 41a side of the push-button body 41, and a rotary shaft 44 having a diameter smaller than the bore diameter of the cylindrical section 12a at the tip of one projection piece 43. The push-button body 41 is internally fitted to the opening 13a, while the rotary shaft 44 is inserted into a hole the cylindrical section 12a and the push-button member 40 is supported and rotated, and the rib 12b is arranged adjacent with respect to a loosely-movable end of the other projection piece 43 so as to prevent the push-button member 40 from rotating in reverse about the rotary shaft 44, at weighting operation with respect to the push-button body 41.
