9. The pedal device (50) according to claim 1, characterized in that, A cover member (165) has a portion covering the rotary potentiometer (162) and the engaging member (163). The cover component (165) has a cover body portion (165a) that is open at the bottom and a frame-shaped portion (165b) that extends axially from the lower end of the cover body portion (165a) toward the rotation axis (162b).

10. The pedal device (50) according to claim 9, characterized in that, The cover component (165) is provided with a rectangular box-shaped part (165a1) and an arc-shaped part (165a2).

11. The pedal device (50) according to claim 1 or 9, characterized in that, The cover component (165) covers a portion of the rotary potentiometer body (162a), the non-rotating portion (162c), and the base side of the rotating shaft (162b) in the rotary potentiometer (162).

12. The pedal device (50) according to claim 10, characterized in that, The rectangular box-shaped portion (165a1) covers the rotary potentiometer body portion (162a) in the rotary potentiometer (162). The arc-shaped portion (165a2) covers the engaging component (163).

13. The pedal device (50) according to claim 7, characterized in that, The cam component also has a generally cylindrical mounting portion, which protrudes radially outward from the mounting portion.

14. The pedal device (50) according to claim 13, characterized in that, The cam portion is located approximately at the axial center of the mounting portion.

15. The pedal device (50) according to claim 13 or 14, characterized in that, The front end of the cam portion is provided with a convex arc-shaped cam surface that protrudes axially upward to the left.
