<P>PROBLEM TO BE SOLVED: To prevent decline in strength of an inner pipe due to resonance while thinning the inner pipe and improving pulsation absorbing performance, in a fuel delivery pipe having a double-pipe structure comprising an outer pipe and the inner pipe. <P>SOLUTION: This fuel delivery pipe 10 has a housing 20 mounted with a plurality of injectors 11 and a metallic cylinder 30 arranged inside the housing 20. Both end parts in the longitudinal direction of the metallic cylinder 30 are fixed to the housing 20. Fuel supplied to a fuel passage between the housing 20 and the metallic cylinder 30 is distributed and supplied to the respective injectors 11, and fuel pressure pulsation is absorbed by elastic deformation of the metallic cylinder 30. The metallic cylinder 30 is fixed to the housing 20 by pins 41, 42 at the approximately center in the longitudinal direction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
