Different tracks 110 cooperating with the contact elastic sheet 80 are formed on the rotating part 60. The rotating part 60 rotates a specific angle to achieve different gear operations. The setting direction of the contact part 901 is perpendicular to the contact groove 101.

[0026] The knob elastic sheet 90 includes a first contact arm 90a, a second contact arm 90b, a main body part 90c, and a fixing part 90d. A first central hole is formed in the main body part 90c.
