Abstract: A rotational mechanism includes a frame, a plurality of rotational units, an inner ring rotatably supported on the frame via the plurality of rotational units, and a rotation driving unit configured to generate power for rotating the inner ring. The inner ring is provided with a protrusion portion on an outer periphery. Each of the plurality of rotational units includes two bearings and a first pressing unit. The first pressing unit is configured to apply pressing forces to the two bearings in opposite directions in a rotational axis direction of the inner race. The protrusion portion is held between the two bearings due to the pressing forces.

Abstract: A display apparatus includes: a display panel configured to transmit light applied to a back side thereof to display an image; an optical member provided behind the back side of the display panel such that a first space is formed between the display panel and the optical member; a light-emitting member provided behind a back side of the optical member to apply light to the back side of the display panel through the optical member; and a flow-path forming member forming a flow path that allows air to flow from one of outside of the display apparatus and a part of the first space corresponding to at least one of four outer edges of the display panel to the other.
