PROBLEM TO BE SOLVED: To provide a sealing device for a rolling bearing which facilitates attachment and detachment of a first seal member held on an inner ring side to improve maintainability.SOLUTION: A sealing device for a rolling bearing includes a seal member for sealing a lubricant between an inner ring and an outer ring. The seal member is structured of a first seal member held on an inner ring side, and a second seal member held on an outer ring side on an inner side from the first seal member in an axial direction. A radial inner end part of the first seal member is held and fixed by an annular step part arranged on a shoulder part of the inner ring, and a seal fixing member detachably attached to the shoulder part on an inner side from the annular step part in the axial direction. An elastic seal lip is in elastic contact with the second seal member. An elastic end surface seal lip which is in elastic contact with an end surface of the annular step part, and an elastic radial seal lip which is in elastic contact with an outer circumference surface of the annular step part are formed on the radial inner end part of the first seal member 31. |
