STRUCTURE FOR CONNECTING BRAKE HOSE WITH MOUTH PIECE

摘要

PROBLEM TO BE SOLVED: To provide a structure for connecting a brake hose with a mouth piece capable of reducing contact corrosion (galvanic corrosion), local corrosion (pitting) and the like occurring at the mouth piece when a mouth piece made of an aluminum alloy is used. SOLUTION: This structure for connecting the brake hose with the mouth piece has un uppermost layer made of ethylene-α-olefin rubber containing a conductive filler. By reducing a content of the conductive filler in the ethylene-α- olefin rubber, a corrosion current generated between the brake hose and the mouth piece is suppressed below a passive state holding current value of the mouth piece.
