Title:
WASHING APPARATUS
Document Type and Number:
Japanese Patent JPH07108232
Kind Code:
A
Abstract:

PURPOSE: To inexpensively stabilize the hermetical close degree between washing tanks even against a manufacturing error or thermal deformation by fixing one surface of the first member of the connection components of the washing tanks to the wall surface of one washing tank through a first elastomer and connecting the other surface thereof to the other washing tank by the second and third members being in contact with the connection components of the tanks and a second elastomer.

CONSTITUTION: Washing tanks 1, 2 are assembled at a constant position. At this time, the positional relation between the washing tanks 1, 2 is different from the aspect of planning because there is a dimensional error in the washing tanks 1, 2 and there is also an error from the aspect of assembling. Therefore, the gap 4 between the washing tanks 1, 2 is not constant and a stepped part is generated between the flange part leading end of the connection component 7 of the tanks and a wall surface. Since the part on the side of the washing tank 1 is divided into a part 6 smaller than the flange part of the component 7 and a part 5 to which a hole slightly larger than the hole of the washing tank 1 is formed, even when the leading end surface of the flange part of the component 7 and the wall surface 3 are not same, a rubber packing 8 expands and contracts and respective constituent components can be always brought to a close contact state.
