PROBLEM TO BE SOLVED: To provide structure of a part connecting section to a fuel tank made of synthetic resin which is constituted so as to secure sufficient welding strength. SOLUTION: In a section where main parts made of material can be welded easily and parts having coated section made of gasoline barrier material are connected to the fuel tank made of synthetic resin wherein at least its surface section is made of material which can be welded easily, in order to make the main parts contact with a heater prior to making the coated section contact with the heater during a process to heat parts by the heater to weld the part to the fuel tank, a step difference is arranged between the edge faces opposing to the heater. Thereby, the welding of material which can be welded easily is prevented from being impeded with the gasoline barrier material. |
