Patent ID: 11022082

Abstract:
Provided is a fuel distribution device 1 including a fuel distribution pipe 3, a fuel pipe 4, and a connecting member 5. The fuel distribution pipe 3 has a seat section 21 having a first convex curved surface 24 formed on an outer circumferential surface thereof. The fuel pipe 4 has a seal section 27 having a second concave curved surface 28 formed on an inner circumferential surface thereof, and a second convex curved surface 29 corresponding to the second concave curved surface 28 is formed on an outer circumferential surface thereof. The connecting member 5 presses the seal section 27 against the seat section 21 from an opposite side of the fuel distribution pipe 3. A radius of curvature SR2 of the second concave curved surface 28 is greater than a radius of curvature SR1 of the first convex curved surface 24.
