A rolling bearing comprising: an inner ring having an inner ring raceway surface on an outer circumferential surface thereof; an outer ring having an outer ring raceway surface on an inner circumferential surface thereof; a plurality of rolling elements that are rollably disposed in a bearing inner space between the inner ring raceway surface and the outer ring raceway surface; and a seal member that is positioned at axial ends of any one raceway ring of the inner ring and the outer ring and blocks the bearing inner space, wherein the seal member defines an oil storage space that bulges outward in an axial direction, characterized in that the oil storage space encloses therein wax-containing lubricant that contains lubricating oil and wax and that based on a liquefaction point which is a predetermined temperature within a temperature range of 10°C to 70°C, is changeable between a liquid state at a temperature exceeding the liquefaction point and a semi-solid state at a temperature equal to or lower than the liquefaction point, wherein the liquefaction point is determined in accordance with "Rules for Regulations on Hazardous Substances in Japan", Chapter 12, Miscellaneous Provision 69-2, the bearing inner space encloses therein grease, wherein the grease contains base oil having the same component as the lubricating oil of the wax-containing lubricant. an inner ring having an inner ring raceway surface on an outer circumferential surface thereof; an outer ring having an outer ring raceway surface on an inner circumferential surface thereof; a plurality of rolling elements that are rollably disposed in a bearing inner space between the inner ring raceway surface and the outer ring raceway surface; and a seal member that is positioned at axial ends of any one raceway ring of the inner ring and the outer ring and blocks the bearing inner space, an outer ring having an outer ring raceway surface on an inner circumferential surface thereof; a plurality of rolling elements that are rollably disposed in a bearing inner space between the inner ring raceway surface and the outer ring raceway surface; and a seal member that is positioned at axial ends of any one raceway ring of the inner ring and the outer ring and blocks the bearing inner space, wherein the seal member defines an oil storage space that bulges outward in an axial direction, characterized in that the oil storage space encloses therein wax-containing lubricant that contains lubricating oil and wax and that based on a liquefaction point which is a predetermined temperature within a temperature range of 10°C to 70°C, is changeable between a liquid state at a temperature exceeding the liquefaction point and a semi-solid state at a temperature equal to or lower than the liquefaction point, wherein the liquefaction point is determined in accordance with "Rules for Regulations on Hazardous Substances in Japan", Chapter 12, Miscellaneous Provision 69-2, the bearing inner space encloses therein grease, wherein the grease contains base oil having the same component as the lubricating oil of the wax-containing lubricant. the oil storage space encloses therein wax-containing lubricant that contains lubricating oil and wax and that based on a liquefaction point which is a predetermined temperature within a temperature range of 10°C to 70°C, is changeable between a liquid state at a temperature exceeding the liquefaction point and a semi-solid state at a temperature equal to or lower than the liquefaction point, wherein the liquefaction point is determined in accordance with "Rules for Regulations on Hazardous Substances in Japan", Chapter 12, Miscellaneous Provision 69-2, the bearing inner space encloses therein grease, wherein the grease contains base oil having the same component as the lubricating oil of the wax-containing lubricant.
