A force detection and transmission mechanism for a pedal includes a pedal body, a force detection module, a rotation shaft, an insulating sleeve, electrically conductive rings, and contact elements. The pedal body has a first accommodating space and a second accommodating space. The force detection module is disposed in the first accommodating space. The rotation shaft passes through the pedal body. Annular accommodating regions and wire perforations are recessed from a surface of the rotation shaft. Transmission wires pass through the wire perforations. The insulating sleeve is sleeved on the rotation shaft. Annular insulating regions are recessed from a surface of the insulating sleeve and correspondingly cover the annular accommodating regions. The electrically conductive rings are respectively sleeved on surfaces of the annular insulating regions, and the transmission wires are correspondingly coupled to the electrically conductive rings. The contact elements abut against the electrically conductive rings, respectively.
