A first half part includes a second raised portion and a third raised portion respectively on the inner side of the hollow body and on the outer side of the hollow body with respect to a first raised portion, the second raised portion and the third raised portion being separated from the first raised portion with a spacing and being lower than the first raised portion. A second half part includes a third raised portion on the outer side of the hollow body with respect to a first raised portion, the third raised portion being separated from the first raised portion with a spacing and being lower than the first raised portion. An internal member includes a second raised portion on the inner side of the hollow body with respect to a first raised portion, the second raised portion being separated from the first raised portion with a spacing and being lower than the first raised portion. As a result, there is provided a high quality hollow body that can be provided at low cost and is cosmetically appealing.

An inertia charge intake manifold is associated with an internal combustion engine having a plurality of cylinders. The intake manifold includes a plurality of elongated separate branch pipes each corresponding to a respective one of the cylinders. The intake manifold also includes a common flange for connecting a first end of each branch pipe to the internal combustion engine. The common flange has a first surface attached to the internal combustion engine. Further, the intake manifold includes a surge tank to which a second end of each branch pipe is connected. The common flange, the surge tank and each branch pipe are made of a hard thermoplastic synthetic resin. The common flange is integrally connected to the surge tank.

A method for joining thermoplastic resin molded products by pressing together joining surfaces of two molded products with electric resistance wire therebetween is provided, wherein the method comprising: a first step in which electric resistance wire is sandwiched between the joining surfaces of two molded products which are to be joined, pressure is applied at a first predetermined pressure, and current of a predetermined value is applied for a predetermined time to the electric resistance wire, so that the resin around the electric resistance wire is melted by the thermal energy produced in the electric resistance wire while the surfaces of the two molded products that are to be joined are held at a predetermined interval; and a second step in which, following the conclusion of the first step, the current being applied to the electric resistance wire is stopped, and a second predetermined pressure is applied to attach the molten resin under pressure.
