PROBLEM TO BE SOLVED: To provide an addition valve supporting device capable of increasing the supporting rigidity of an addition valve to be supported in an exhaust pipe.SOLUTION: A housing 22 of an addition valve supporting device 20 for supporting an addition valve 14 is mounted on a connection flange 21 to be connected to the exhaust pipe by mounting means which has a leakage restricting member 29 and a heat radiation member 27D. The addition valve supporting device 20 includes a supporting stay 23 having one end fixed to the connection flange 21 and the other end fixed to the housing 22, in addition to the mounting means. The supporting stay 23 supports the housing 22 at a position apart from a position of support by the mounting means in the axial direction of the housing 22. |
