Pedal support structure and pedal support system

A pedal support structure comprising:

• a first slider;
• a second slider;
• a first guide that guides the first slider in such a way that the first slider is configured to be slid linearly;
• a second guide that guides the second slider in such a way that the second slider is configured to be slid linearly;
• a first coupling part to which the first slider and the second slider are rotatably coupled, thereby coupling the first slider and the second slider to each other;
• a pedal rotatably coupled to the first coupling part;
• and
• load means for applying a load to a movement of the first slider or the second slider, wherein
• the first guide and the second guide are extended in such a way that they intersect with each other,
• a rotation axis of the pedal is disposed away from a rotation axis of the first slider and a rotation axis of the second slider and is disposed away from a midpoint of a line that connects the rotation axis of the first slider and the rotation axis of the second slider, whereby the rotation axis of the pedal moves along an elliptical trajectory, and
• the load means applies a load to the movement of the first slider or the second slider when the pedal is moved in a predetermined direction and the rotation axis of the pedal is located below the major axis of the elliptical trajectory, and does not apply a load to the movement of the first slider or the second slider when the pedal is moved in a predetermined direction and the rotation axis of the pedal is positioned above the major axis of the elliptical trajectory.
