Claims

[Scope of Claim for Utility Model Registration] A pedal arm, a support bracket that rotatably supports the pedal arm, a spring mounting portion that rotates together with the pedal arm, and a connection between the spring mounting portion and the support bracket. In a pedal depression force reduction device including a torsion coil spring disposed between the torsion coil spring and the first coil part,
a second coil section, a second coil section and a second coil section;
a swing end located between the coil part, a first pivot end located at the tip of the first coil part, and a second pivot end located at the tip of the second coil part. The swinging end is locked to the spring attachment part, and the first pivoting end connects the center of rotation of the pedal arm and the swinging end in a state before the pedal is depressed. It is located on the pedal depression side relative to the line segment, and when the pedal arm is depressed beyond a predetermined angle, it is located on the pedal return side relative to the line segment connecting the rotation center of the pedal arm and the swing end. The second pivot end is pivoted to the support bracket in a manner such that the second pivot end is located near the line segment connecting the center of rotation of the pedal arm and the above-mentioned swinging end before the pedal is depressed, or the position of the second pivot end is located closer to the pedal arm than near this line segment. A pedal depression force reducing device characterized in that the device is pivotally connected to a support bracket so as to be located on the return side of the pedal.
