Abstract
An inner half cylinder and an outer half cylinder are brazed to each other to form a cylindrical header tank. Both ends of tubes are connected to the inner half cylinder. An opening of the outer half cylinder is communicated with an opening of a joint pipe. A tongue portion which is provided on the periphery of the opening of the outer half cylinder is inserted and curled in the opening of the joint pipe so as to fix the joint pipe on the outer half cylinder firmly.
