PROBLEM TO BE SOLVED: To provide a low-cost seal to have high sealing safety and mounting workability through variation of arrangement and combination of a plurality of seal members. SOLUTION: This bearing seal is provided with a seal lip 3, a reinforcing ring 32, and the radial lip 4 of a seal part 31. The radial lip 3a of the seal part 31 is brought into contact with a shaft 2 and the side lip 3b is protruded obliquely to below on the inside diameter side from the drum part of the seal part 31. The tip thereof is inclined toward the inside diameter side and the outer peripheral surface thereof is brought into slide contact with the side lip 3b. This constitution causes a plurality of contact seal members to keep high seal safety and be excellent in mounting workability and also in molding properties, and reduce a cost. |
