PROBLEM TO BE SOLVED: To provide a lamp body device for a bicycle pedal and a bicycle capable of illuminating LEDs of the front and rear of the pedal in the respective same colors, regardless of right or left of the pedal, and regardless of which of treads a rider steps, with a more simple structure than ever.SOLUTION: A lamp body device for a bicycle pedal comprises: two lamp body parts arranged on both vertical sides of a pedal body rotatably supported by a pedal shaft of a bicycle, as well as arranged in two-fold symmetry with respect to the pedal shaft. Each of the lamp body parts comprises: a piezoelectric element generating electric power according to a pressure change; a first light emitting part illuminating in a first luminescent color by using the electric power generated by the piezoelectric element; and a second light emitting part illuminating in a second luminescent color different from the first luminescent color by using the electric power generated by the piezoelectric element, and emitting light toward a direction opposite to that of the first light emitting part.SELECTED DRAWING: Figure 1

    【課題】より簡易な構成で、ペダルの左右及び運転者がどちらの踏面を踏むかに係わらずペダルの前方及び後方のLEDをそれぞれ所定の色に発光させる自転車ペダル用灯体装置および自転車を提供する。【解決手段】自転車のペダル軸に回転可能に支持されるペダル本体の上下方向の両面に配置され、且つ前記ペダル軸に対して2回対称で配置された2つの灯体部を備え、前記灯体部は、圧力変化に応じて発電する圧電素子と、前記圧電素子で発電した電力により第1の発光色で発光する第1発光部と、前記圧電素子で発電した電力により前記第1の発光色とは異なる第2の発光色で、前記第1発光部とは相反する方向に発光する第2発光部と、を備える。【選択図】図1
