PROBLEM TO BE SOLVED: To provide a structure which does not throw out foreign substances, such as grease, base oil component in the grease, fragments of a seal material 18, outside a rolling bearing at a low cost. SOLUTION: The seal material 18 is attached to a flat portion 21 of a sealed plate 11f. The seal material 18 is held between the flat portion 21 and the inside side surface 19a of an engaging groove 12. The end rim portion 22 of the inside side surface 19a is brought into contact with the middle portion of the width of the seal material 18. The seal material 18 prevents the leakage of the grease or the base oil component in the grease. In addition, fragments produced by the breakage of the seal material 18 cannot be thrown out outside the rolling bearing. COPYRIGHT: (C)2005,JPO&NCIPI
