PURPOSE: To decrease a manhour and to lower a cost by mounting key guide piece caps, which are formed at tips extended from a base body of a subchassis in a comb-tooth shape and slide on keys, on key guide pieces. CONSTITUTION: The chassis 1 is formed of metal and the key guide pieces 1a which guides pressed keys are erected corresponding to the keys. The subchassis 2, on the other hand, has extension parts 2-2 extended from its base body 2-1 in the comb-tooth shape, and those base body 2-1 and extension parts 2-2 are integrally molded out of synthetic resin, in one body. The key guide piece caps 2a mounted on the key guide pieces 1a are formed at the tips of the extension parts 2-2. The extension parts 2-2 are in the comb-teeth shape, so they can deform to the right and left and the tips of the key guide pieces 1a erected on the chassis 1 are arcuate, so the key guide piece caps 2a can easily be mounted on the key guide pieces 1a. |
