To provide a changer used for a cycle which is driven by human power, capable of outputting and providing rotation with peripheral velocity according to input characteristic and smooth and stepless gear change.SOLUTION: A changer comprises as a pair of rotation plates, two rotation plates which are a drive (input) rotation plate 1 having a rotation axial direction and a follower (output) rotation plate 2, and comprises a linkage shaft 8 on an optional position of the drive rotation plate 1 for transmitting rotation to the follower rotation plate 2, and a passive long hole (groove) 9 on the follower rotation plate 2 for receiving rotation, and by operating (changing) a center distance between rotation shafts of centers of the drive rotation plate 1 and the follower rotation plate 2, rotation of the follower rotation plate 2 is provided by stepless optional gear change and a peripheral velocity characteristic of a pseudo elliptical gear (sprocket) which is convenient for human power characteristic.SELECTED DRAWING: Figure 1

    【課題】人力駆動の自転車等に用いる変速機に於いてスムーズで無段な変速と入力特性にあった周速度の回転を出力し提供する。【解決手段】回転軸方向を持つ駆動(入力)回転板1と従動(出力)回転板2の二つの回転板を一対で備え且つ駆動回転板1の任意の位置に回転を従動回転板2に伝えるための連接軸8を設け、もう一方の従動回転板2に回転を受けるための受動長穴(溝)9を設けて構成し、駆動回転板1と従動回転板2の各中心の回転軸間の中心距離を操作(変える)することで無段な任意の変速と人力特性に都合のよい疑似楕円ギア(スプロケット)の周速度特性で従動回転板2の回転を提供する。【選択図】図1
