Abstract
A burner device placed upstream of an exhaust treatment device mounted in an exhaust pipe to raise a temperature of an exhaust gas, comprises a fuel supply valve for supplying fuel into the exhaust pipe, an igniter that ignites the fuel supplied from the fuel supply valve, and a burner catalyst held in the exhaust pipe through a support member. The support member is formed in a corrugated shape in cross section including outer arc-shaped portions in contact with the exhaust pipe, inner arc-shaped portions in contact with an outer peripheral member of the burner catalyst, and coupling portions for coupling the outer arc-shaped portions and the inner arc-shaped portions to each other.
