Abstract:
[Problem] To provide a delivery pipe that is ultrasonic-welded and has high strength while taking advantage of being made of a resin material that is highly resistant to corrosion, is low cost, and is lightweight, and also to provide, by using an existing ultrasonic welding apparatus, a delivery pipe that eliminates the need for a pulsation damper and that is sufficiently durable under use in a high-pressure engine. [Solution] This resin-made delivery pipe 10 comprises: a cylindrical body 12 having one end closed and the other end left open; and a circular plug 14 for blocking said other end of the body 12. This delivery pipe 10 is characterized in that: a plurality of injector connection ports 16 are provided to a trunk section of the body 12; and joining portions between the body 12 and the plug 14 are multiply ultrasonic-welded at a first joining portion and a second joining portion.
