<P>PROBLEM TO BE SOLVED: To provide a key mounting structure hard to cause backlash and light leakage since an operation key can be easily fitted to a panel frame from the front side. <P>SOLUTION: When the operation key 1 is fitted to the panel frame 2 from the front side, a pair of elastic arm pieces 12 are inserted in corresponding cutout portions 22, and the hook-like tip parts 12a of both elastic arm pieces 12 are made to abut on regulating projections corresponding to the tip parts. Thereby, a positioning wall 26 regulates horizontal movement of both elastic arm pieces 12, the regulating projections 23 regulate movement of both elastic arm pieces 12 toward the front side, movement of the operation key 1 toward the back side is regulated by the peripheral fringe part of the opening 20 of the panel frame 2, and movement of a stopper claw 14 toward the front side is regulated by a regulating wall 25. After temporarily holding the operation key 1 in this way, the vicinity of the tip parts 12a of both elastic arm pieces 12 are vertically held between the upper movement regulating part 27 of the panel frame 2 and the protruding piece 60 of a support member 6, and the operation key 1 is thereby supported in a cantilever form with the held spot acting as a fulcrum part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
