The conventional simple punching type bearing seal shown in Japanese Patent Publication No. 2 has a large diameter due to its simple structure as shown in FIG. Since the bearing seal has a very small mounting space, it may interfere with the retainer (6) that holds the rolling body (5) in the bearing, and in order to avoid this interference, the meat of the portion that may be in contact with the retainer (6). It is necessary to form the pressure thinly (a pre-molding method can also be performed as a similar molding method) or to detour-form the interference portion into a convex shape to separate the two portions.

っている。In manufacturing such a bearing seal, an elastic sealing material (3) is laminated on a flat reinforcing plate (2), and then a press punch (4) is formed as shown in FIG.
When a deformation stress is applied by punching with, the elastic sealing material (3) having high flexibility is formed on the reinforcing plate (2).
Since a deformation load is applied through it, it is not possible to perform compression molding of an accurate shape. When the reinforcing plate (2) is preliminarily deformed and shaped and then the elastic sealing laminated material (A3) is laminated and formed, the reinforcing plate (2) is thermally expanded during mold vulcanization of the elastic sealing laminated material (A3). It has a structural defect that the diameter pitch is easily changed and it cannot be placed accurately in the mold, which is one of the major causes that the molding accuracy and sealing performance cannot be improved.

It is most suitable to form a metal thin plate having a plate thickness of 5 mm to 1.2 mm to mold the unevenness while ensuring rigidity. In the uneven shape formed by compression on the reinforcing plate (2), As shown in FIG. 3, in addition to the detour convex shape that does not interfere with the retainer (6) of the rolling body (5), the structure of FIG. 6 mainly intended to improve its rigidity, or FIG. 7 for giving other action. Alternatively, it is also possible to form a shape having complicated irregularities as shown in FIG. This will be described in detail. In FIG. 6, a ring-shaped convex portion (c1) is provided on the flat surface portion of the bearing seal to improve the strength of the entire peripheral surface. Further, in the concavo-convex shape shown in FIG. 7, the intermittent ridges (c2) are provided, and it is expected that the internal lubricating oil will be retained in the recesses on the back surface of the ridges (c2).
In addition, the structure shown in FIG. 8 forms a wavy unevenness (c3) on the peripheral edge, and the resistance stirring action of the wavy unevenness (c3) causes a scattering / shaking effect of dust or water drops to be attached.
