    • In a bicycle transmission, a driven sprocket wheel body includes a plurality of driven sprocket wheels which are connected with a drive sprocket wheel by an endless chain. A derailleur is provided for changing over the winding of the endless chain among the plurality of driven sprocket wheels. The drive sprocket wheel is prevented from moving beyond a given range even when an excessive external force is applied to the drive sprocket wheel at the time of traveling. A slide member is movable in the axial direction of a drive shaft and is provided between the drive shaft and a drive sprocket wheel. A drive sprocket wheel movement restricting member is provided which sandwiches the drive sprocket wheel position setting member and moves in the axial direction of the drive shaft together with the drive sprocket wheel.
    • 在自行车传动装置中,从动链轮主体包括多个由链轮与驱动链轮连接的从动链轮。 提供了一种拨链器,用于在多个从动链轮之间切换环形链的绕组。 即使在行驶时对驱动链轮施加过大的外力,也可以防止驱动链轮移动超过给定范围。 滑动构件可在驱动轴的轴向方向上移动并且设置在驱动轴和驱动链轮之间。 提供驱动链轮移动限制构件,其夹持驱动链轮位置设定构件并与驱动链轮一起沿驱动轴的轴向方向移动。
