PROBLEM TO BE SOLVED: To provide the optimum height of a saddle when a bicycle is driven.SOLUTION: A bicycle seat clamp 30 comprises: a fixing clamp 2 connectable to a seat post 1; a feed screw 3 having a screw part that can change the height of a saddle connectable to the fixing clamp 2; a handle 4 having a screw and held by a bearing 5, the screw being freely rotated by its being engaged with the feed screw 3, and the screw being able to further feed the feed screw 3 according to an amount of rotation; a rotation stopper 6 holding the feed screw 3 such that the feed screw is non-rotatable, and holding a core exposing part and the bearing 5; and a seat clamp 7 connectable to the rotation stopper 6, engaged with a seat tube 9 of a bicycle frame, and to which pressure is applied to such a degree that the seat post 1 is not separated upward and the saddle is not rotated. The height of the saddle during travel of the bicycle can be changed by rotating the handle 4 by means of a fixing key 8 connectable to the seat clamp 7 so as to be non-rotatable, and set in a slit in the seat tube 9 of the bicycle frame so as to be non-rotatable.SELECTED DRAWING: Figure 1
【課題】自転車を運転するときに、最適なサドル高さを提供する。【解決手段】シートポスト1を連結可能な固定クランプ2と、固定クランプ2と連結可能なサドル高さを変える事ができるねじ部を有する送りねじ3と、送りねじ3と係合して回転自由であり回転量に応じて送りねじ3が伸張できるねじを有し、ベアリング5に保持されるハンドル4と、送りねじ3を回転不能に保持し、芯だし部とベアリング5を保持する回転止め6と、回転止め6と連結可能で自転車フレームのシートチューブ9と係合し、シートポスト1が上方に抜けず、サドルが回転しない程度に与圧されるシートクランプ7と、シートクランプ7と回転不能に連結可能で自転車フレームのシートチューブ9のスリット部に回転不能に設置する固定かぎ8によるハンドル4を回転させることで自転車走行中にサドル高さを変更できる自転車用シートクランプ30。【選択図】図1
