A bearing (10) , which is subjected to a radial load on the shaft tip side and supported by multiple rows of rollers (15) in the shaft direction, equalizes the load carried by the rollers (15) disposed in each row and reduces the peak value of the acting load. The bearing back surface region, where the analyzed rolling element load, which takes bearing structure deformation into consideration, becomes higher than the calculated theoretical value for when there is no structure deformation, is provided with a rigidity-adjusting section (SA), which reduces support rigidity in the radial direction from the bearing center more for regions with a greater analyzed rolling element load. |
