Abstract

PURPOSE: To seal securely by forming, in the outer ring, apenetrating port which connects the outer peripheral of the inner ring with the atmosphere.
CONSTITUTION: An outer ring 1 and an inner ring 2 are engaged to each other through zigzag sealing gap 3. Then, at least one penetrating port is bore in the radius direction in the outer ring 1, and the extension 5 of said penetrating port 4 is cut in the inner ring 2. As the result, water dropes penetrated into the sealing gap 3 is given a centrifugal force by the rotating inner ring 2. Then, water drops reach the groove part 5 going beyond the first peak of the zigzag sealing gap 3 to be discharged to the outside through the penetrating port 4 by the action of the pump impeller.
