Abstract
A seal plate 8 is located between the outer ring 1 and inner ring 3, and the outer diameter 11 side of the this seal plate 8 is fastened to the stationary ring 1, and the lip 13 an the inner-diameter 12 side comes into sliding contact with or keeps a clearance with respect to the inner ring 3 to secure seal performance, and there is a protruding section 19 formed on the side surface 18 on the outside of the seal plate 8, so that a clearance 29 is formed between the protruding section 19 and the peripheral part 25 near the bearing. Consequently, it is possible to provide a sealed-type rolling bearing where the seal performance is improved without increasing cost, by providing not only sealing in the lip portion but also sealing between the bearing and the peripheral part near the bearing.
