PROBLEM TO BE SOLVED: To provide a bridge that can readily adjust torsional rigidity between two adjacent frame pipes of a bicycle.SOLUTION: A rigidity adjusting bridge 1 for a bicycle frame according to the present invention includes: two plate members 2 and 3 for bridging across two adjacent frame pipes 51 of a bicycle and holding the frame pipes 51 in a sandwich form via a plane defined by the central axes of the frame pipes 51; and fastening components 4 for fastening the two plate members to each other. The torsional rigidity between the two adjacent frame pipes can be adjusted by selecting one of plural plate member pairs each having a different thickness or width or composed of a different material (having a different Young's modulus).

    【課題】自転車の隣接する2本のフレームパイプ間のねじれ剛性を容易に調整することができるブリッジを提供すること。【解決手段】本発明の自転車のフレーム剛性調整用ブリッジ1は、自転車の隣接する2本のフレームパイプ51を、その両フレームパイプ51の中心軸により形成される面を間に、両フレームパイプ51にまたがってサンドイッチ状に挟み込むための、2枚の平板状部材2、3と、前記2枚の平板状部材同士を締結する締結具4とから成ることを特徴とする。2枚の平板状部材の厚さや幅、或いは素材(のヤング率)が異なるものを複数セット用意しておき、それらを取り替えることで、2本のフレームパイプのねじれ剛性を調整することが可能となる。【選択図】図1
