<P>PROBLEM TO BE SOLVED: To provide a joint structure for connecting a fuel pipe part with a fuel injection device capable of improving the assembly property and the strength against pulling-out. <P>SOLUTION: This joint structure is provided with a first fuel pipe 10 fixed to a fuel injection device 1 side and a second fuel pipe 20 having inner periphery having different dimension from that of the first fuel pipe 10. Inner periphery of the fuel pipe on one side among the first and second fuel pipes has such dimension that allows the insertion of outer periphery of the fuel pipe on the other side. A projecting part 20c extending in the radial direction and a recessed part 10a capable of locking the projecting part 20c in the axial direction are provided between the inner periphery of the fuel pipe on one side and the outer periphery of the fuel pipe on the other side. The recessed part 10a has an opening part 10a1 allowing the insertion of the projecting part 20c, a recessed part 10a2 in the axial direction extending in substantially axial direction from the opening part 10a1, and a recessed part 10a3 in the peripheral direction extending in substantially peripheral direction from the recessed part 10a2 in the axial direction. <P>COPYRIGHT: (C)2004,JPO |
