<P>PROBLEM TO BE SOLVED: To provide a fuel supply system for an automobile equipped with a function for preventing fuel pulsation and capable of reducing the weight and the cost. Ž<P>SOLUTION: The fluid coupling A1 used for the fuel supply system of the vehicle includes a coupling body constituting a fluid passage 5 and made of a material mainly composed of resin, a bellows 7 disposed in the fluid passage 5 and absorbing pulsation of the fluid by being deformed in a direction same with pulsation of the fluid flowing through the fluid passage 5 and comprising resin or rubber, and a support body 6 fixed to the coupling body by rotation welding and welded and connected to the bellows 7. Thus, the fluid coupling is small and low cost and can suppress pulsation of the fluid efficiently with a limited space, and can contribute for reduction of the weight and the cost when being applied to the fuel supply system of the automobile.
