ある。It should be noted that, in a state in which the tip (lower end) of the second protrusion 7 is simply in contact with the annular recess before vibration welding, the tip (lower end) of the second protrusion 7 has a welding margin portion (not shown) for vibration welding. No)
The first protrusion 4 and the extended portion 11 of the fuel distributor A are both in non-contact with the lid member B with a distance corresponding to the welding margin. This distance in the non-contact state is filled because the welding margin portion of the second protrusion 7 is melted and disappears by the subsequent vibration welding, and after the vibration welding, the first protrusion 4 and the extended portion 11 are formed. Is in contact with the lid member B and has two concentric annular closed chambers 10,1
0 is formed, and the welded portion, that is, the portion of the second protrusion 7 is cut off from the fuel passage 2 of the fuel distributor A. In FIG. 3, 9 is a resin waste generated by vibration welding, which is the second protrusion 7
It is formed by melting the welding margin portion provided at the lower end of the.

During assembly, the annular recess of the flange portion 3 of the fuel distributor A is brought into contact with the welding margin portion of the lower end of the second protrusion 7 of the lid member B so as to cover the opening of the fuel passage 2, and this contact is made. In this state, the contact point C between them and the fuel passage 2 are blocked by the raised adhesive layer 12 to seal the inner annular recess,
In this shut-off state, the contact points C of the two are joined by vibration welding, and the lid member B is assembled to the flange portion 3 of the fuel distributor A. Note that, of course, the adhesive constituting the adhesive layer 12 is
By virtue of this property, the viscosity is maintained in the state before vibration welding, the viscosity gradually increases due to the change over time, and it solidifies after vibration welding. A and lid member B
It is not affected by vibration welding with and no resin waste is generated.

In this second embodiment, the bulging portion 13 of the pipe material 6 in the first embodiment is not inserted into the lid member B but the bulging portion 13 is formed. The O-ring 1 is inserted into the fuel passage 2 and pressed by the lid member B so as not to be pulled out, and the bulging portion 13 is made of a non-plastic material and serves as a blocking means.
By attaching 4,14, the welding margin is provided at the lower end of the second protrusion 7 of the lid member B, and thus the welding margin is provided between the extended portion 11 of the fuel distributor A and the lid member B. Even if there is a gap, the contact point C between the two is cut off from the fuel passage 2 of the fuel distributor A. Since the O-ring 14 is usually made of rubber and is made of a material different from that of the plastic parts, it is not affected by vibration welding of the plastic parts and no resin slag is generated. Since the other parts are the same as those in the first embodiment, the same components are designated by the same reference numerals and detailed description thereof will be omitted.
