Gasket

Abstract

In order to provide a gasket which has a good handling property as a gasket used for a fuel battery or a gasket for an hard disc drive, can be easily integrated with the other end mounting member even in the case that the other end mounting member such as a separator or the like is a material having low strength or a thin plate, and has good mounting workability, a gasket is having a sheet-shaped gasket mounting member provided with a sticking function on one face, and a gasket main body made of a rubber-type elastic member integrated with the sheet-shaped gasket mounting member, and the gasket is mounted to the other end mounting member on the basis of the sticking function of the sheet-shaped gasket mounting member.

1 . A gasket comprising: 
 a gasket main body made only of a rubber; and    a sheet-shaped gasket mounting member provided in parts on a periphery of said gasket main body,    wherein said gasket is mounted to a mating mounting member on the basis of a sticking function provided on one face of said sheet-shaped gasket mounting member, wherein said mating mounting member is a reaction electrode portion for a fuel battery, or an electrolyte membrane corresponding to a component part of the reaction electrode portion.    
     
     
         2 . The gasket as claimed in  claim 1 , wherein a cross sectional shape of the gasket main body is an O-ring shape.  
     
     
         3 . The gasket as claimed in  claim 1 , wherein a cross sectional shape of the gasket main body is a lip shape.  
     
     
         4 . The gasket as claimed in  claim 1 , wherein the gasket main body is a gasket main body for a both-face portion to be arranged on both faces of said mating mounting member, the sheet-shaped gasket mounting member is integrally formed in said gasket main body, and the gasket is bent in two at a time of being mounted to said mating mounting member so as to be stuck to both faces of said mating mounting member.  
     
     
         5 . The gasket as claimed in  claim 4 , wherein the sheet-shaped gasket mounting member integrally has a portion stuck to one face side, a portion stuck to another face side, and a connection portion connecting said both portions of said mating mounting member, and is bent in said connection portion at a time of being mounted.  
     
     
         6 . The gasket as claimed in  claim 5 , wherein said connection portion is provided with a bending position specifying portion such as a slit, a perforated line or the like for facilitating the bending of the connection portion.
