Abstract:
1. A bearing member comprising: a bearing part that rotationally supports a rotational body and that includes a sliding contact area where the rotational body continuously slidably contacts the bearing part during rotation thereof, and a non-sliding contact area that is formed outside of the sliding contact area and where the bearing part is free from contact by the rotational body during the rotation thereof; a load application part formed in the sliding contact area, wherein the load application part is configured to contact the rotational body and to continuously apply a load to the rotational body in a radial direction of the rotational body; a plurality of holding grooves formed in the sliding contact area in the rotation axis direction of the rotational body, wherein the plurality of holding grooves each having an opening at only one end, and the plurality of holding grooves are adapted to hold a lubricant that is to be supplied to the sliding contact area between the rotational body and the load application part; an injection groove is formed in a part of the non-sliding contact area in a rotation axis direction of the rotational body; and a force receiving surface that is formed outside the bearing member, wherein the bearing part is formed inside the bearing member, the force receiving surface is configured to receive a force and to transmit the force to the load application part, thereby resulting in the load applied by the load application part, and openings of the plurality of holding grooves are formed on the same side of the bearing part in the rotation axis direction of the rotational body.
