Abstract
A rotary device includes a first rotor, a centrifugal element, a first urging member, and a second urging member. The first rotor includes a guide surface and is disposed to be rotatable. The centrifugal element is attached to the first rotor. The centrifugal element is radially movable along the guide surface by a centrifugal force acting thereon in rotation of the first rotor. The first urging member is configured to urge the centrifugal element. The second urging member is configured to urge the centrifugal element in a direction opposite to a direction of urging by the first urging member. The first and second urging members are further configured to rotate the centrifugal element toward the guide surface.
