Claims

[Scope of utility model registration request]

A filler neck is integrally provided on the side surface of the header tank body so that the water supply port at the tip of the filler neck is located above the top surface of the header tank body,
The capacity of the header tank body above the root position of the filler net is made to be able to accommodate expansion due to a rise in cooling water temperature, and
The upper part of the tank body and the side part of the filler neck are communicated with each other by a communication pipe, an elastic member is disposed in the filler neck, and a radiator cap is attached to the water supply port in the filler neck. When the radiator cap is removed from the water supply port, the tubular member that is pushed in against the biasing force of the elastic member and is supported by the elastic member is slid. a small hole is formed in the side wall of the tubular member so that the communication pipe and the filler neck communicate with each other when a radiator cap is attached to the water supply port;
A radiator header characterized in that a sealing member is fitted around the outer periphery of the tubular member for airtightly closing the connection end on the filler neck side of the communication pipe when the radiator cap is removed from the water supply port. tank.
