Pedal assembly

A pedal assembly, comprising:

• a pedal arm in which one end is joined to a predetermined stationary member through a supporting member in a pivotal manner;
• a pedal pad formed on the other end of the pedal arm;
• a spring that applies a reaction force to the pedal arm against a torque derived from a pedal force applied to the pedal pad to rotate the pedal arm around the supporting member;
• and
• another spring that applies a reaction force to the pedal arm against the torque derived from the pedal force, wherein:
• one end of the spring is joined to the predetermined stationary member through a fixed pivotal joint,
• the other end of the spring is joined to an arm pivotal joint arranged in the pedal arm between the pedal pad and the supporting member,
• the arm pivotal joint is arranged at a site withdrawn from a neutral line drawn between the supporting member and the fixed pivotal joint in a reciprocating direction of the pedal arm,
• an angle between a line drawn between the supporting member and the arm pivotal joint and the neutral line is narrower than an angle between a line drawn between the fixed pivotal joint and the arm pivotal joint and the neutral line,
• one end of the another spring is joined to the predetermined stationary member through another fixed pivotal joint,
• the other end of the another spring is joined to another arm pivotal joint arranged in the pedal arm,
• the another arm pivotal joint is withdrawn from the neutral line in the reciprocating direction of the pedal arm, and
• the spring and the another spring include a coil spring and a torsion coil spring.
