Title:

FLOW PASSAGE FORMING STRUCTURE AND METHOD OF MANUFACTURING THIS FLOW PASSAGE FORMING STRUCTURE

Document Type and Number:

Japanese Patent JP2012057652

Kind Code:

A

Abstract:

To provide a flow passage forming structure without causing welding failure of a welding part even when the structure is enlarged.

This flow passage forming structure 1 is constituted of three or more of resin molds, and the projected area when viewed from the vertical direction to a welding surface of the welded resin mold, is restrained in 5-300 cm². For example, when welding the first resin mold 10, the second resin mold 20 and the third resin mold 30 for vibratingly welding the first resin mold 10 to one surface and vibratingly welding the second resin mold 20 to the other surface, the first resin mold 10 and the second resin mold 20 are adjusted so that the projected area becomes 5-300 cm² when viewed from the vertical direction to the welding surface.
