Abstract
A coupling device includes a first rotating body and a second rotating body disposed coaxially with each other and rotatable relative to each other. The coupling device includes a spacer disposed between the first rotating body and the second rotating body; and a pressing member for performing pressing of at least one rotating body of the first rotating body and the second rotating body against the spacer. The spacer is formed of an elastic member, and generates a frictional force between the spacer and the one rotating body when the pressing member performs the pressing. The one rotating body and the spacer are formed to have a configuration that allows the one rotating body or the spacer to be idled when torque larger than the frictional force acts between the one rotating body and the spacer.
