Claims

[Scope of utility model registration request]

In an exhaust pipe support structure in which a catalyst case holding a catalyst body is interposed in the middle of the exhaust pipe and the catalyst case is attached to a fixed member side to support the exhaust pipe, the central curved portion is connected to the catalyst case. A support bracket is provided, which covers the catalyst case and has both side edges fixed to a case flange protruding from the catalyst case, and the support bracket is provided at a position corresponding to a flange side notch formed in the case flange. An exhaust pipe support structure characterized by forming a recess on the bracket side.
