Separate plate for a control valve used in an automatic transmission and method for fabricating same

A separate plate for a control valve used in an automatic transmission, comprising:

• a metal plate;
• a not yet foamed rubber layer formed on at least one surface of said metal plate, said not yet foamed rubber layer being 90 .mu.m to 300 .mu.m thick;
• and
• a foam rubber layer formed on said not yet foamed rubber layer which is a surface layer of the separate plate, said foam rubber layer being 80 .mu.m to 200 .mu.m thick, and said foam rubber being reinforced with a cloth, the cloth having one of inorganic and organic fibers woven therein.

In a control valve for an automatic transmission, a branching container having oil paths and a separate plate for sealing the oil paths, said separate plate comprising:

• a metal plate;
• a non-foamed rubber layer on at least one surface of said metal plate, the non-foamed rubber layer being 90 .mu.m to 300 .mu.m thick;
• and
• a foam rubber layer on said non-foamed rubber layer remote from the metal plate, said foam rubber layer being a surface layer of said separate plate, said foam rubber layer being 80 .mu.m to 200 .mu.m thick and being reinforced by at least one of inorganic fibers, organic fibers, and unwoven cloth.
