<P>PROBLEM TO BE SOLVED: To secure fixation strength by enabling the fixation state of a key base body and a woody part to visually be confirmed. <P>SOLUTION: A key structure K1 comprises an upper plate body 10 made of light-transmissive synthetic resin, a key base body 20 made of transparent synthetic resin, and the woody part 30 made of a woody material. A lower surface 30a of the woody part 30 is bonded to an upper surface 22a of an extending part 22 of the key base body 20 with an adhesive, and the bonding state can be visually confirmed since the key base body 20 is made of a transparent member. The extending part 22 is also provided with a through hole 22b for adhesive injection. A bag-shaped part 24 including a lens part 24a is formed integrally on the front of the key base body 20 and a light irradiation part 40 is arranged below the bag-shaped part 24. A through hole 30a formed in the front of the woody part 30 guides the irradiation light from the light irradiation part 40 toward the upper plate body 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
