る。(Problems to be Solved by the Invention) However, since the conventional curved ear seal member for ball bearings has a shape and structure as shown in Fig. 3, when it is caulked into the seal groove of the outer ring, the curved ear seal member does not fit into the curved portion of the outer ring. Disadvantages include distortion and improper sealing. This drawback is particularly noticeable in stainless steel ear bend seal members for ball bearings.
そこで、この発明は前記の従来の欠点を解決す
ることを目的として提案するものである。 Therefore, the present invention is proposed for the purpose of solving the above-mentioned conventional drawbacks.

In the figure, numeral 3 indicates a bent portion of the ear bending portion 2, and an odd number of holes 1 are formed in the bent portion 3 at predetermined intervals. Further, in the figure, 4 is an outer ring, 5 is a seal groove of the outer ring 4, and 6 is a groove for a ball (not shown). Incidentally, the ball bearing ear bend seal member in the embodiment is made of stainless steel. In addition, in this invention, the shape of the hole 1 is not critical;
Needless to say, it can be bored in any shape.

う特有な効果を奏する。(Effects of the Invention) The curved ear sealing member for a ball bearing according to the present invention configured as described above, when caulked into the seal groove 5 of the outer ring 4 as shown in FIG. The bent part 2 fits into the seal groove 5 in a state where the piece 7 is bent inward. In this state, the distortion that occurs in the bent part 2 is caused by the bending part 3 of the bent part 2 being spaced at a predetermined distance. Since the hole 1 is absorbed into the hole 1 which is provided around the required number of times, it has the unique effect of being properly sealed.
