Abstract
A separate plate for use in a valve body of an automatic transmission has a gasket bonded to each side of the separate plate. The gasket is provided with boxes which are different in configuration from bores provided in the separate plate. Bores are punched out in the separate plate and the gasket coated with an adhesive, separately from each other, and then the separate plate and the gasket are bonded together in one unit. Accordingly, it is possible to provide a separate plate having improved assembling efficiency and superior resistances to heat, oil and rupture.
