PROBLEM TO BE SOLVED: To provide a bicycle transmission having higher speed change performance, and to provide a bicycle interior transmission hub.SOLUTION: A bicycle transmission includes: a first transmission part including a first rotating body to which man power driving force is transmitted; a second transmission part including a second rotating body coupled to the first rotating body and a rotary shaft rotatably supporting the second rotating body; a connection member which can move relative to the second rotating body in an axial direction of the rotary shaft and connect the second rotating body with the rotary shaft so that the man power driving force transmitted from the first transmission part is transmitted to the rotary shaft through the second rotating body; and a release part which utilizes the man power driving force transmitted from the first transmission part to move the connection member in the axial direction and thereby release connection between the second rotating body and the rotary shaft.SELECTED DRAWING: Figure 4

    【課題】より高い変速性能を有する自転車用変速機および自転車用内装変速ハブを提供する。【解決手段】自転車用変速機は、人力駆動力が伝達される第1回転体を含む第1伝達部と、前記第1回転体に連結される第2回転体、および、前記第2回転体を回転可能に支持する回転軸を含む第2伝達部と、前記第2回転体に対して前記回転軸の軸方向に移動可能であり、前記第1伝達部から伝達される人力駆動力が前記第2回転体を介して前記回転軸に伝達されるように、前記第2回転体と前記回転軸とを連結可能な連結部材と、前記第1伝達部から伝達される人力駆動力を利用して前記連結部材を前記軸方向に移動させることによって、前記第2回転体と前記回転軸との連結を解除する解除部と、を備える。【選択図】図4
