Abstract
A rotation assistance device (1) is equipped with a rotating shaft body (11) and multiple rotation assistance bodies (20), which are equipped with rotating bodies (40). The rotating bodies are equipped with a rotation-promoting body (22), having a mass that maintains rotation, and with a spring shaft (23), one end of which is connected to the shaft body (11) and the other end of which is connected to the rotation-promoting body (22), and which expands and contracts in the lengthwise direction by means of an elastic body. The rotation assistance bodies also are equipped with guide rails (21), which guide the rotation-promoting bodies (22) of the rotating bodies (40) so as to rotate in an elliptical orbit. The rotating bodies (40) are attached to the shaft body (11) such that their respective attachment angles around the axis of rotation are displaced with respect to each other.
