Document Type and Number:
Japanese Patent JPH06297505
Kind Code:
A
Abstract:
PURPOSE: To provide an integrally bonded structure wherein air-tightness is high and leaking of air is not generated from the respective parts by tightly bonding a flange part to a pipe main body.
CONSTITUTION: A pipe main body 10 is formed by blow molding. A flange part 30 is integrally formed in the end of the pipe main body 10 by injection molding. An annular embedding part 20 to be buried integrally in the flange part is formed in the end part of the pipe main body and a tip part 21 having an acute shape is formed in the annular embedding part 20, which is melted by heat in injection molding of the flange part and integrally joined to the flange part.
