<P>PROBLEM TO BE SOLVED: To ensure a proper turning operation of a key body and easiness of molding a turning mechanism, and to enhance the rigidity of the turning mechanism. <P>SOLUTION: A link part 40 includes the first arm 41 and the second arm 42 and they are connected so that the key body 20 freely turns in a key touch/release direction with respect to a base end 30. A front end and a rear end of the first arm 41 are connected to a rear end of the key body 20 and a front end of the base end 30 via connections F1 and R1, respectively, and a front end and a rear end of the second arm 42 are connected to the rear end of the key body 20 and the front end of the base end 30 via connections F2 and R2, respectively. In the link part 40, the first arm 41 and the second arm 42 are integrally formed and they does not overlap in planer view. <P>COPYRIGHT: (C)2011,JPO&INPIT |
