WELDING STRUCTURE OF SYNTHETIC RESIN MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a welding structure of a synthetic resin member containing reinforcing fibers suitable for forming a container by welding cylindrical upper and lower members improving adhesive strength without increasing the size of a welding margin and attempting improvement in productivity and compactness of the structure. SOLUTION: To-be-welded members 2A, 2B of a thermoplastic resin containing reinforcing fibers are welded through a thermoplastic resin spacer 40. The content of reinforcing fibers of the spacer 40 is made less than that of the members 2A, 2B.
