Freewheel clutch for bicycle has frictional force between holder and fixed portion that is smaller than engagement force between driven shaft and engagement portion, but larger than spring resilient force

摘要

The engagement portions (5,6) are set between a drive shaft (2) and a driven shaft (4). A holder is frictionally coupled to a fixed portion. A spring (8) holds the disengagement of the engagement portions with the driven shaft. A frictional force between the holder and fixed portion is smaller than an engagement force between the engagement portions and driven shaft, but larger than a spring resilient force.
