    • A bicycle derailleur gear changer has a device for guiding the chain and the device has chain-guiding and chain-adjusting pulleys which are mounted between the ends of two cheek plates. The device is movable to effect gear changes by transferring the chain from one to another of sprockets attached to the hub of the bicycle rear wheel. The cheek plates are specially shaped with radial extensions adjacent the chain-guiding pulley, the extensions terminating in turned over edges facing away from the pulley to prevent possible jamming of the gear changer when the chain is driven in the reverse direction.This is a continuation, of application Ser. No. 539,852 filed Jan. 9, 1975 now abandoned.
    • 自行车拨链器变速器具有用于引导链条的装置,并且该装置具有安装在两个颊板的端部之间的链条和链条调节滑轮。 该装置可移动以通过将链条从一个链轮传递到另一个连接到自行车后轮的轮毂的链轮来实现变速。 脸颊板是特殊形状的,具有邻近链条导向滑轮的径向延伸部分,延伸部终止于背向皮带轮的边缘,以防止当链条沿相反方向被驱动时可能的变速器卡住。
