いる。In order to solve the above problems, in the first invention,
In a rolling bearing with a filter seal, in which a rolling element is installed between the outer ring and the inner ring, and an annular filter seal is attached to the end surface of the cage that holds the rolling element, the filter seal mounting means has a plurality of attachment means on the end surface of the cage. The engaging groove is formed, and the protrusion between the adjacent engaging grooves is inserted into the insertion hole provided in the filter seal, and the annular seal retainer plate that overlaps the outer surface of the filter seal is brought into contact with the end surface of the cage. The contact surface is fixed by ultrasonic fusion.
