[Problem that the idea aims to solve]

However, according to the accelerator pedal of the electromagnetic powder auto clutch vehicle mentioned above, The switch 7 is fixed to the side of the switch arm 2 with a screw 53 and a nut 54. Ru. The accelerator pedal arm 5 is arranged on the nut 54 side, and the distance shown in FIG. 6 ( stroke) make different movements within a. In such a configuration, when operating the pedal Accelerator pedal arm 5 may fall due to deformation or looseness (misalignment), or switch arm may Due to deformation of the accelerator pedal arm 2, etc., the accelerator pedal arm 5 may be (protruding end) and the nut 54.

[0005] If the pedal is operated repeatedly in this condition, the screw 53 and nut 54 This will cause the accelerator pedal switch 7 to become loose and the position of the accelerator pedal switch 7 to shift. In addition to not being able to operate the switch in the correct position, switch arm 2 and accelerator pedal There is an inconvenience that the dull arm 5 cannot operate normally.

[0006] To solve this inconvenience, change the length of the screw so that it does not have a protruding end. Alternatively, you can cut off the protruding end of the screw, but it is not recommended to fix the switch. To ensure long-term reliability, the screw end must be left protruding at a certain length. Otherwise, the nut may become loose or come off easily.

[0007] Therefore, this idea was developed by improving the accelerator pedal of electromagnetic powder auto clutch vehicles. This is an attempt to resolve the shortcomings.
