1. A power transmission apparatus comprising:
- a case;
an outer sleeve on which a gear is supported;
an inner sleeve which is concentrically disposed within the outer sleeve;
a first bearing that supports the inner sleeve;
a second bearing and a third bearing that supports the outer sleeve on the case in both sides of the gear;
a clutch device disposed between the first bearing and the third bearing in a direction of a common rotational axis of the outer sleeve and the inner sleeve and adapted to connect and interrupt a power transmission between the outer sleeve and the inner sleeve; and
a ring shape actuator adapted to generate a driving force for actuating the clutch device,wherein the power transmission between the outer sleeve and the inner sleeve is executed by passing a transmitting power through a radially internal space of the ring shape actuator from the clutch device, andwherein the power transmission between the outer sleeve and the inner sleeve is executed by passing the transmitting power through the radially internal space of the ring shape actuator from one side of the ring shape actuator to the other side of the ring shape actuator in the direction of the common rotational axis.

Abstract
A power transmission apparatus is provided with a first rotational member, a second rotational member, a clutch device for coupling a power transmission between the first rotational member and the second rotational member, and a ring shape actuator of the clutch device. A rotational axis of one of the first rotational member and the second rotational member penetrates through a radially internal space of the ring shape actuator.
