摘要

PROBLEM TO BE SOLVED: To provide a reed valve for an EGR device that is not subject to corrosion and breakage even when an exhaust gas contains a high concentration sulfur oxide at a higher temperature than 200°C and a method for producing the same.

SOLUTION: A reed valve for an EGR device includes a reed valve 24 comprising a valve seat housing 31 and a reed valve body 32 for opening/closing the valve seat housing 31 that is connected to an EGR pipe 21, wherein the valve seat housing 31 and the reed valve body 32 are formed thereon with a polyamide-imide resin coating in which fluororesin powder and inorganic powder are dispersed.
