Abstract
If a member made of rubber containing carbon black and a member made of aluminium alloy come into contact with each other under existence of an electrolytic solution, corrosion of the aluminium alloy member would proceed. Such corrosion of the aluminium alloy member can be suppressed by selecting a surface resistivity (surface electric resistivity) of the rubber member at 10.sup.6 .OMEGA. or higher, and more preferably 10.sup.7 .omega. or higher.
