Fuel distribution device

A fuel distribution device comprising:

• a fuel distribution pipe which distributes and supplies fuel to a plurality of fuel injection devices;
• a fuel pipe connected to the fuel distribution pipe;
• and
• a connecting member which connects the fuel distribution pipe and the fuel pipe,
• wherein the fuel distribution pipe has a seat section having a first convex curved surface formed on an outer circumferential surface thereof so as to be reduced in diameter in a convex curved surface shape toward a tip on the fuel pipe side,
• the fuel pipe has a seal section in which a second concave curved surface, which is enlarged in diameter in a concave curved surface shape toward the tip on the fuel distribution pipe side and against which the first convex curved surface abuts, is formed on an inner circumferential surface thereof, and a second convex curved surface corresponding to the second concave curved surface is formed on an outer circumferential surface,
• the connecting member presses the seal section against the seat section from an opposite side of the fuel distribution pipe, and
• a radius of curvature of the second concave curved surface is greater than a radius of curvature of the first convex curved surface.
