Abstract
A lid member includes a tubular section housed inside an opening section, an external flange section closing the tubular section and extending therefrom across an outer boundary, and a seal-member mounting section extending downward from the edge of the external flange section and having a seal member. A flange-equipped sleeve includes a sleeve section attached to a neck section and an internal flange section extended from the sleeve section across the outer boundary and attached to an inner wall of the tank body. The flange-equipped sleeve contains a resin having a higher heat-resistant temperature than a resin constituting the tank body. When the lid member closes the opening section, the tubular section is housed inside the sleeve section. The external flange section contacts the top of the neck section and the sleeve section. An inner circumference of the seal member is attached to the outer boundary of the neck section.
