According to the invention, the device includes a speed change operating device having for itself a performance of a reverse input allowing device so as to effectively bring the stepless speed change device into practical use. In this manner, the stepless speed change device becomes light weight and small-sized as a whole.

摘要： An inscribed transmission device includes a substantially crescent-shaped space between an internal gear and an external gear circumscribingly in mesh with each other. The device comprises a rolling space holder having two sets of two rollers whose centers are situated on radial axes in the crescent-shaped space on both sides of a straight line connecting centers of the internal and external gears. The internal and external gears are provided with roller rolling portions on which the rollers roll. The two sets of rollers are supported by a block member or side plates. The rolling space holder smoothly moves to keep the crescent-shaped space, thereby preventing unintentional disengagement of the internal and external gears.

摘要： The disclosed speed-change gear includes a fitting secured to the frame of a bicycle, a parallel link means having an outside link and an inside link whose one ends are pivotally connected to the fitting, a movable member pivotally connected to the opposite ends of the inside and outside links, a changeover frame rotatably secured to the movable member, which changeover frame carries a guide wheel and a tension wheel of a chain, and a cam means adapted to selectively move said movable member so as to shift the speed-change ratio by changing the position of said changeover frame to shift the chain to the desired step of a multi-step sprocket assembly of the bicycle. The cam means has a spring-biased cam rotatably mounted on a shaft connecting the outside link to the fitting, which cam rotates together with a wire-operated reel coaxially mounted on said shaft. The rotation of the cam actuates said parallel link means through a lever pivotally carried by a shaft connecting the inside link to the fitting.
