Claims

[Scope of utility model registration request]

In the case where the pedal 19 is swingably mounted on the fixed side and is swingably biased in the return direction, the cam 24 is swingably mounted on the fixed side, and there is a gap between the cam 24 and the fixed side. A spring 26 is provided to apply an elastic force, and the cam 24 is connected to the pedal 19.
The pedal depression force reduction is characterized in that the spring 26 is interlocked and connected via the cam surface 34 so that the direction of action of the rocking biasing force on the pedal 19 by the spring 26 changes as the pedal 19 swings. Device.
