Seal device

Abstract

A seal device has a base member and an elastic member. The elastic member adheres to the base member so as to cover substantially the entire surface of the base member without any adhesive material. Thereby, the elastic member and the base member can be easily removed from each other.

What is claimed is:  
     
         1 . A seal device comprising: 
 a base member; and    an elastic member adhering to the base member so as to cover substantially the entire surface of the base member without any adhesive material.    
     
     
         2 . The seal device according to  claim 1 , wherein the base member is made of metal.  
     
     
         3 . The seal device according to  claim 1 , wherein at least the part of base member is arranged to receive force due to caulking the elastic member.  
     
     
         4 . The seal device according to  claim 1 , wherein the base member is made of one of resin and fiberglass reinforced plastic.  
     
     
         5 . The seal device according to  claim 1 , wherein the base member is annular in shape.  
     
     
         6 . The seal device according to  claim 1 , wherein each side of the base member is recessed to form a groove, and the part of elastic member occupies the groove.  
     
     
         7 . The seal device according to  claim 6 , wherein the bottom of the groove is wider than the opening of the groove.  
     
     
         8 . The seal device according to  claim 6 , wherein the groove continuously extends from one end to the other end on each side of the base member.  
     
     
         9 . The seal device according to  claim 1 , wherein the base member forms a through hole, which extends in thickness, and the elastic member formed on each side of the base member interconnects through the through hole.  
     
     
         10 . The seal device according to  claim 1 , wherein the elastic member is formed by insert mold.  
     
     
         11 . The seal device according to  claim 1 , wherein the elastic member is made of rubber.  
     
     
         12 . The seal device according to  claim 11 , wherein the elastic member is made of synthetic rubber such as acrylonitrile butadiene rubber.  
     
     
         13 . The seal device according to  claim 1 , wherein the seal device is a lip seal.  
     
     
         14 . The seal device according to  claim 1 , wherein the seal device is a gasket.  
     
     
         15 . A compressor comprising: 
 a housing;    a rotary shaft supported by the housing; and    a seal device comprising: 
 a base member having through hole, which is formed to extend through the base member in thickness; and  
 an elastic member adhering to the base member so as to cover substantially an entire surface of the base member, wherein the elastic member on each side of the base member interconnects through the through hole.  
   
     
     
         16 . The compressor according to  claim 15 , wherein the seal device is interposed between the housing and the rotary shaft.  
     
     
         17 . The compressor according to  claim 15 , wherein the seal device is accommodated in the housing.  
     
     
         18 . The compressor according to  claim 15  further comprising: 
 a cylinder block connected to the housing;  
 wherein the seal device is interposed between the housing and the cylinder block.  
 
     
     
         19 . The compressor according to  claim 15 , wherein the seal device is a lip seal.  
     
     
         20 . The compressor according to  claim 15 , wherein the seal device is a gasket.  
     
     
         21 . A compressor comprising: 
 a housing: 
 a rotary shaft supported by the housing; and  
 a seal device comprising: 
 a base member having grooves, which is recessed on each side of the base member, the bottom of each groove being wider than the opening of the groove; and  
 an elastic member adhering to the base member so as to cover substantially an entire surface of the base member, wherein the part of elastic member on each side of the base member occupies the grooves.
