PROBLEM TO BE SOLVED: To provide an oil feeder enhancing the mechanical strength against external force affecting a welded position, in a structure in which an injection port forming member 40 is welded to a resin-made passage forming member 20.SOLUTION: In an oil feeder 10, an injection port forming member 40 having an inlet 41a is welded to a passage forming member 20. The passage forming member 20 and the injection port forming member 40 are formed of a resin material welding each other, and are sealed by welding between the passage forming member 20 and the injection port forming member 40 with welding portion Wd along the whole circumference. The passage forming member 20 has a reinforcing member 25 which is arranged annularly along the whole circumference of the passage forming member 20. The reinforcing member 25 is formed of a material mechanical strength of which is greater than that of the passage forming member 20, and the reinforcing member 25 and the welding portion Wd are placed on a same plane at right angle from the center line of the fuel passage 11 P. |
