タの過熱保護装置。[Scope of Claim for Utility Model Registration] An overheat protection device for a catalytic converter to prevent deterioration of the catalyst due to high temperature overheating due to the flow of high temperature exhaust gas into the catalytic converter, with respect to the flow of exhaust gas in the exhaust pipe. Air cooling fins are disposed upstream of the catalytic converter installation site so as to surround the exhaust pipe, and one end of the air cooling fin is fixed to the exhaust pipe and the other end is engaged with a supporting member of the air cooling fin. Temperature-sensitive deformation of the fixing member such that when the temperature of the exhaust pipe is below a predetermined temperature, the air cooling fin is moved away from the exhaust pipe, and when the temperature of the exhaust pipe is higher than the predetermined temperature, the air cooling fin is brought into close contact with the exhaust pipe. What is claimed is: 1. An overheat protection device for a catalytic converter, characterized by comprising a temperature-sensitive member having special characteristics.
