摘要： A bicycle transmission of an internally mounted type, the transmission having a simple structure and capable of being universally installed on various bicycles. A rotating claw body (1) is fitted on a main shaft (51). Main gears (2, 3, 4, 5) corresponding to the number of shifts are arranged side by side on the outer periphery of the rotating claw body (1). An auxiliary shaft (6) is placed in parallel with the main shaft, and auxiliary gears (7, 8, 9, 10) individually functioning in operative association with the main gears at a predetermined speed ratio are co-rotatably supported by the auxiliary shaft (6). Ratchet claws (15, 16, 17, 18) individually corresponding to the main gears are arranged on the rotating claw body (1). Ratchet teeth (19) with which the ratchet claws engage are formed on the inner peripheral side of the main gears. When a switchover member (20) for causing the ratchet claws to project from and retract into the outer peripheral surface of the rotating claw body (1) is operated, a ratchet claw (15, 16, 17, 18) is engaged with and disengaged from the ratchet teeth (19) to switchover between the main gears (2, 3, 4, 5) that transmit drive power via auxiliary gears (7, 8, 9, 10). In this way, the speed ratio of rotation of the input side and output side is changed to shift gears.

摘要： A saddle lifting device for a bicycle, enabling lifting of the saddle of the bicycle with the driver seated on the saddle and having enhanced safety and a simple structure. Urging force of a stroke spring (10) for using a saddle in a lifting direction is set to a magnitude that allows the saddle to lower when the weight of the driver seated on the saddle is directly applied to the saddle and that allow the saddle to lift when the driver seated on the saddle works pedals. When the driver is not seated on the saddle, resistance disables disengagement of switchover operation between a ratchet claw (13b) for stopping lifting and a ratchet gear (14). When the driver is seated on the saddle, the urging force of the stroke spring (10) is cancelled by a load acting on the saddle, reducing the resistance, and this allows the engagement between the ratchet claw (13b) for stopping lifting and the ratchet gear (14) to be released by the switchover operation.
摘要翻译：一种用于自行车的马鞍提升装置，能够使坐在马鞍上的驾驶员提升自行车的马鞍并且具有增强的安全性和简单的结构。当将坐在鞍座上的驾驶员的重量直接施加到鞍座上时，用于在提升方向上使用鞍座的行程弹簧（10）的推压力被设定为允许鞍座降低的大小，并且允许鞍座当司机坐在马鞍上时，起升踏板。当驾驶员未坐在马鞍上时，阻力使得用于停止提升的棘爪（13b）与棘轮（14）之间的切换操作脱离。当驾驶员坐在鞍座上时，行程弹簧（10）的作用力被作用在鞍座上的负载抵消，从而减小了阻力，并且这允许棘爪（13b）与止动件棘轮（14）由切换操作释放。
