Document Type and Number:
Japanese Patent JP6955241
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation transmission mechanism capable of achieving a bicycle, etc. better than a conventional one in usability.SOLUTION: A rotation transmission mechanism 1A includes an internal rotation member 3 put on a crank shaft 2 of a bicycle, and an external rotation member 4 rotatably disposed to the internal rotation member 3. The internal rotation member 3 includes a disc-shaped internal rotation member body 3a having a crank shaft insertion hole, and five outer peripheral convex parts 3f formed integrally with the internal rotation member body 3a that project on the outer peripheral side of the internal rotation member body 3a. The external rotation member 4 includes an annular part rotatably disposed to the internal rotation member 3 outside the outer peripheral convex parts 3f, and five inner peripheral convex parts 4d formed integrally with the annular part so as to project to the inner peripheral side of the annular part, which are arranged alternately with the outer peripheral convex parts 3f. Elastic deformation parts 6A are disposed between the outer peripheral convex parts 3f and the inner peripheral convex parts 4d on the rotation direction side of the outer peripheral convex parts 3f in advancing. The elastic deformation parts 6A are formed with spaces 6a partially.SELECTED DRAWING: Figure 10
