Claims

[Scope of utility model registration request]

A resin tank having an outwardly protruding stepped portion on its lower edge, and a seat plate having a gutter-like groove on its circumferential edge and a caulking claw on the outer wall of this groove, are stepped into the groove by packing. In a heat exchanger in which a tank and a seat plate are assembled by fitting parts together and crimping and bending the crimping pawl, a bead or flange is provided at least in the crimping and bending part of the crimping pawl to strengthen rigidity. An assembly structure between a tank and a seat plate in a heat exchanger characterized by:
