の内側面に貫通孔を有する補強板を焼着して凹部を設け
該凹部に吸込切口を設けた密封体などが開発された。Conventionally, a sealing body that seals against pressure increase / decrease in the bearing caused by shaft rotation is pressed against one surface in the bearing in accordance with the increase / decrease, and sliding noise or vibration is generated, resulting in remarkable wear. I was hasty. As a measure against this,
-24167, such as a sealed body in which a window penetrating inside and outside the bearing is provided in an appropriate place of a shield plate, and an oil filter made of wire mesh or the like is fixed to the window, or made of an elastic body such as Jitsuko Sho-45-26492 A sealed body has been developed in which a reinforcing plate having a through hole is baked on the inner surface of the main body to form a recess and a suction cut is provided in the recess.

回避し難い欠点があった。In addition, regarding the adhesiveness of the elastic body to the reinforcing member, there are many avoidances such as the need to use an expensive and strong adhesive in order to adhere the elastic body to the reinforcing member having an untreated smooth surface. There was a difficult drawback.
本発明はこの様な欠点を除去し、内外の圧力差を迅速に

としている。The present invention is an elastic body 1 as shown in FIG. 2 which is mounted between two mutually rotating members such as a bearing and seals the inside and the outside of the two members.
And a reinforcing member (2), which is a sealing member (2) joined to a part of the elastic body (1) for the purpose of reinforcing the same.
Is formed from a plate-shaped metal, and the metal plate-shaped reinforcing member 2a is provided with a plurality of protrusions 3 to form fine crack through holes 4 at the top or bottom of the protrusion surface. There is.

いものとなる。In order to provide the crack through hole 4 as shown in FIG. 1 for exhibiting the filter effect in the reinforcing member 2 made of a plate-like metal, the uneven projection 3 is formed by a known method such as compression forming or stamping forming.
However, a local material strain is generated even inside the top portion or the bottom portion of the projection formed at this time, and the material strain portion is broken to form a small crack. In implementing the method, select the metal material to be used, and adjust the width and depth of the cracks according to the size, height, and height of the protrusions to meet the required air flow rate. The formed crack through hole 4 is a minute gap similar to the structure of cracks, salmon, cracks, etc. as shown in the physical condition of formation and its name. It is a highly effective filter that completely prevents

きるなど様々な形状が実施できる。In carrying out the present invention, for example, a sealing body A as shown in FIG. 2 is given. In the sealing body A, a sealing member formed of an elastic body 1 is provided with a reinforcing member 2a having a crack through hole 4 on the outside. It is arranged so that it is exposed and connected, and it exerts a ventilation function and a filter function. At this time, the protrusion processing 3 provided on the reinforcing member 2a is not limited to the partial molding as shown in FIG. 2, and the entire surface thereof may be subjected to the protrusion processing 3 to form a reliable fitting portion with the elastic body 1. Various shapes can be implemented.
