PROBLEM TO BE SOLVED: To provide a rotation transmission mechanism which is used with attachment to a rotational shaft such as a crank shaft of a bicycle and can switch between a first drive mode of using an elastic deformation part and a second drive mode of using no elastic deformation part.SOLUTION: A rotation transmission mechanism 1 includes a clutch plate 6 which is provided so as to be unable to rotate and able to approach/separate with respect to an external rotation member 4 on a side of a cover part 4c of the external rotation member 4. A convex part 3b of an internal rotation member has an engagement convex part 8 formed on a surface facing the clutch plate 6. An engagement hole engaged in such a manner that rotation is impossible with respect to the engagement convex part 8 of the internal rotation member when approaching the cover part 4c of the external rotation member 4 is bored on the clutch plate 6.SELECTED DRAWING: Figure 1
【課題】 自転車のクランク軸等の回転軸に装着して使用される回転伝達機構であって、弾性変形部を利用する第1の運転モードと弾性変形部を利用しない第2の運転モードを切り替えることが可能な回転伝達機構を提供する。【解決手段】 回転伝達機構1は、外部回転部材4のカバー部4cの側方に、当該外部回転部材4に対して回転不能かつ接離可能に設けられたクラッチ板6を備えている。内部回転部材の凸部3bには、クラッチ板6との対向面に係合凸部8が形成されている。クラッチ板6には、外部回転部材4のカバー部4cに接近したときに内部回転部材の係合凸部8に対して回転不能に係合する係合孔が穿設されている。【選択図】 図1
