A tank includes a tank wall that has an opening, which is configured into a generally rectangular form that extends in a longitudinal direction and a lateral direction while a cross section of the tank wall, which is perpendicular to the longitudinal direction of the opening, is curved, and a tank foot is formed to extend all around the opening of the tank wall. A gate position is placed in a longitudinal center portion of one side surface of the tank foot, which extends in the longitudinal direction of the tank wall.

Tank for heat exchanger, and method for manufacturing the same

A heat exchanger includes a core portion, a pair of header tanks, and an elastically-deformable sealing member. The header tanks are arranged on both end sides of the core portion. The header tank includes a core plate and a resin tank body, which define a tank space. The sealing member is disposed at an end part of the tank body located adjacent to the core plate. The sealing member has a loop shape to enclose the tank space when viewed from the core portion and is formed integrally with the end part of the tank body. The end part of the tank body includes a protrusion portion at least one of inward and outward of the sealing member. The protrusion portion encloses the tank space when viewed from the core portion and projects from the end part of the tank body toward the core plate.
