る。2. Description of the Related Art When a sealing device is fitted and fixed to an inner ring or an outer ring of a bearing by utilizing rubber elasticity, if a rotation torque caused by lip sliding is larger than a slip torque of a fitting portion of the sealing device, the rotation is performed. Rotation around the shaft occurs. In such a case, in order to prevent the rotation of the sealing device, the rubber tightening margin of the fitting portion must be set large, and if this is done, the fitting property to the fitting groove becomes poor and the fitting failure may be caused. Defective fitting is apt to occur, such as breakage. To dislike this, a structure for fixing a sealing plate using a push-spread fixing action as disclosed in Japanese Utility Model Publication No. 47-19422 has been proposed.

As shown in (1), an enlarged portion (5) is formed at the peripheral edge of the sealing plate (B), and a bent edge (61) is formed at the peripheral edge of the metal core (6) for reinforcing the sealing plate (B). , The bent edge (6
1) is spread toward the raceway side, and the enlarged portion (5) is fitted into the fitting groove (1) to increase the amount of engagement to obtain a desired fixing force.

をそのまま実施することができない。However, such a fitting structure in which the enlarged portion (5) made of an elastic body is engaged with the fitting groove (1) has a strong elastic force, so that the fixing force is not strong. If the material is easily loosened due to deterioration with time or vibration, etc., the sealing force may be lost, and if the bent edge (61) is pushed and widened in order to increase the fitting force, the radial expansion deformation of the cored bar (6) may occur. This proposal cannot be implemented as it is because other problems occur, such as the shape balance of the sealing plate (B) being greatly deviated and the shape accuracy of the inner diameter portion being extremely low.

If the fitting shelf (11) in contact with the back of (1) is not secured in a large area, there is a risk of easily losing the deformation stress and falling inside the bearing, which significantly restricts the shape of the bearing. The present invention has been made in view of the above-described drawbacks, and has as its object to provide a fitting structure of a sealing device that has good mounting properties, has excellent engagement strength, and prevents co-rotation.
