 sleeving the elastic supporting member onto the mounting shaft, wherein at least one of the elastic supporting member and the mounting shaft is coated with a first adhesive being cured; 
 adhering the elastic supporting member and the mounting shaft together, by heating the mounting shaft sleeved with the elastic supporting member to make the first adhesive hot-melted and then cured to form the first adhesive layer; and 
 sleeving the tubular member onto the elastic supporting member and adhering the tubular member to the elastic supporting member through the second adhesive layer formed from a second adhesive. 
   
     
     
         10 . The method according to  claim 9 , further comprising:
 coating the second adhesive being cured to at least one of the tubular member and the elastic supporting member prior to sleeving the tubular member; and   the adhering the tubular member to the elastic supporting member through the second adhesive layer formed from the second adhesive comprises:   heating the elastic supporting member sleeved with the tubular member to make the second adhesive hot-melted and then cured to form the adhesive layer.   
     
     
         11 . The method according to  claim 9 , further comprising:
 coating the second adhesive in liquid state to at least one of the tubular member and the elastic supporting member prior to sleeving the tubular member, wherein the second adhesive in liquid state is cured after sleeving the tubular member.   
     
     
         12 . The method according to  claim 9 , wherein the sleeving the tubular member onto the elastic supporting member comprises:
