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 first and second inner dies are combined to form a molding cavity, in which a fluidic material is charged and hardened for molding a tubular member, which has a side surface at least partially defining a projected portion being higher at one end than the other end. The first inner die forms an inner space of the tubular member. The second inner die forms the projected portion. A first actuating unit draws the first inner die from the other end along a first moving path, which is substantially linear along an axis of the tubular member. A second actuating unit draws the second inner die from the other end along a second moving path, which bulges toward the inner space and passes through the inner space.

Molding apparatus and method for molding

In a case connection structure for connecting connection end portions of both case members, a boss portion is formed in one of the connection end portions to protrude to the other one of the connection end portions, and a recess portion into which the boss portion is fitted is formed in the other one of the connection end portions. A slit is provided in the boss portion, and a press-fitting portion is provided in the recess portion to be press-fitted into the slit. While the boss portion is fitted into the recess portion, the press-fitting portion is press-fitted into the slit to expand the boss portion to an outer side, so that an outer surface of the boss portion press-contacts the recess portion.
