<P>PROBLEM TO BE SOLVED: To suppress consumption of resin by reducing strength required for a key guide disposal part, while securing frame rigidity. <P>SOLUTION: A planar part 54 on which a finish stopper 55 is mounted, a key guide connection part 49 wherein a key guide part 50 is formed above integrally and protrusively, and a front side support part 41 abutting directly on a shelf board 19 are formed integrally with a frame 40 respectively, and are integrated continuous parts in a body over a plurality of key areas in the key arrangement direction. The key guide connection part 49 is formed on a position different from the planar part 54 and the front side support part 41 in a lateral view, and the key guide connection part 49 and the front side support part 41 are connected mutually only by a longitudinal rib 46. <P>COPYRIGHT: (C)2010,JPO&INPIT |
