Abstract
A rotation device includes an output shaft, at least one rotatable rotary plate member arranged so that its rotation axis and the output shaft are coaxial, at least one weight member fixed to the rotary plate member, for biasing position of the center of gravity from the rotation axis of the rotary plate member, and at least one clutch mechanism arranged between the rotary plate member and the output shaft, for separating the rotary plate member and the output shaft with each other at a predetermined rotation angle. The clutch mechanism connects the rotary plate member with the output shaft when the center of gravity of the weight member descends, and separates the rotary plate member from the output shaft when the center of gravity of the weight member rises.
