Claim 15:
16. A rotary device comprising:
a first rotor disposed to be rotatable, the first rotor including an accommodation portion having a first guide surface and a second guide surface, the first and second guide surfaces facing both sides in a circumferential direction;
a second rotor disposed to be rotatable with the first rotor and be rotatable relative to the first rotor;
a centrifugal element disposed within the accommodation portion, the centrifugal element disposed to be radially movable by a centrifugal force acting thereon in rotation of the first or second rotor;
a first rolling member disposed between the first guide surface and the centrifugal element, the first rolling member configured to roll on the first guide surface in accordance with rotation of the centrifugal element about the rotational axis thereof; and
a second rolling member disposed between the second guide surface and the centrifugal element, the second rolling member configured to roll on the second guide surface in accordance with the rotation of the centrifugal element about the rotational axis thereof,
wherein
the centrifugal element includes
a centrifugal element body including a first end portion and a second end portion in the circumferential direction,
a first rotary part attached to be rotatable to the first end portion of the centrifugal element body, and
a second rotary part attached to be rotatable to the second end portion of the centrifugal element body,
the first rolling member is disposed between the first guide surface and the first rotary part, the first rolling member configured to roll on the first guide surface in accordance with rotation of the first rotary part about a rotational axis thereof, and
the second rolling member is disposed between the second guide surface and the second rotary part, the second rolling member configured to roll on the second guide surface in accordance with rotation of the second rotary part about a rotational axis thereof.
