PROBLEM TO BE SOLVED: To provide a bearing and a rotary body support device capable of supporting a rotary body such as a swing arm by a single body and reducing a wall thickness of the rotary body support device. SOLUTION: Raceway surfaces 2a, 3a in contact with a rolling body 4 are provided on an outside diameter face of an inner ring 2 and on an inside diameter face of an outer ring 3, and a plurality of rolling bodies 4 are interposed between these raceway surfaces 2a and 3a. A support means 5 for supporting a moment load and a thrust load between the inner ring 2 and the outer ring 3 is provided. This support means 5 may be provided as a four point contact ball bearing to serve also as a radial load support means and may be provided as a thrust sliding bearing separately. A clearance in the radial direction between the raceway surfaces 2a, 3a of the inner ring 2 and the outer ring 3 and the rolling bodies 4 is a negative clearance. |
