<P>PROBLEM TO BE SOLVED: To allow lower ends of two link members to be easily assembled to a support substrate having a detachment prevention function, in a keyboard device whose keytop is supported by the link members in a manner capable of being freely lifted/lowered. <P>SOLUTION: A lower end 30a of a link member 30 supporting a keytop is provided with a shaft 33, and protrusions 34 protruding downward are also formed on the lower end 30a. Support recesses 11a and openings 13 are formed on a support substrate 10. When the shaft 33 is inserted in the support recesses 11a, the protrusions 34 enter the respective openings 13. The shaft 33 is sufficiently prevented from being detached even if an opposing dimension h between the protrusion 34 and an opposing edge 14 of each opening 13 is not too great. Because the opposing dimension h is relatively short, it only requires a little force to assemble the shaft 33. <P>COPYRIGHT: (C)2012,JPO&INPIT |
