Claims

[Scope of utility model registration request]

A hakama part that protrudes outward along the opening of the resin tank body is integrally formed, and the opening end face and side surface of this hakama part are covered with a recessed part integrally formed along the outer periphery of the seat plate. With an O-ring interposed between the opening end surface of the part and the bottom surface of the recess, a seat plate claw formed along the outer peripheral edge of the seat plate is placed at a position opposite to the opening end surface of the hakama part. In a connection structure between a heat exchanger tank and a seat plate which are caulked and fixed to a caulking surface formed, dovetail grooves are formed at predetermined intervals along the caulking surface of the hakama portion and widen towards the tank body side. a concave groove is formed, and the shape of the seat plate claw corresponds to the concave groove,
A connection structure between a heat exchanger tank and a seat plate, characterized in that the seat plate pawl is fitted into the groove.
