New description: [New technical field] The present invention relates to a bicycle component, in particular to a folding pedal. [Prior Art] The pedals protruding from the left and right sides of the bicycle cause inconvenience in folding. For the lack of 'Taiwan Patent No. 304493, a folding pedal is proposed. When folding, the pedal body is pushed inward to shift the short shaft column. At the gap to the pedal body, the pedal body is pivoted relative to the center seat with the long axis column as a pivot point. However, if the gap in the patent application is blocked by dirt, gravel, etc., the short-axis column will not be able to enter and exit the gap, which will result in the inability to fold or return to use. In addition, when returning to the use state, the tension spring must be compressed and the short-axis column is aligned with the notch to return to the use state, and it is not easy to operate. Further, in the prior patent, the groove for the reflector mounting overlaps with the long slot, so that the thickness of the pedal body is thus thinned, thereby reducing the structural strength of the pedal body. [New content] Therefore, the object of the present invention is to provide a folding pedal which is simple in operation and structurally stable. So, the new folding pedal includes a step frame unit and one
