Abstract: A balance plate with differentiated amplitude of swing has a pedal, elastic supporting component, first axial supporting part and second axial supporting part. The pedal has a stepping surface and a bottom surface. The elastic supporting component has a footing end to be supported by the ground, and a fitting end to link with the bottom surface of the pedal. The first axial supporting part is fitted on the footing end of the elastic supporting component and configured along the first axial direction, so that the pedal can swing up and down along the first axial direction. The second axial supporting part is configured on the footing end of the elastic supporting component and configured along a second axial direction, so that the pedal can swing along the second axial direction. Said axial directions are perpendicular to each other. The axial supporting parts are in differentiated shapes.
