<P>PROBLEM TO BE SOLVED: To avoid losing pulsation absorbing performance, even when abnormality is caused, while increasing the pulsation absorbing effect of an inner pipe absorbing fuel pressure pulsation of a fuel delivery pipe. <P>SOLUTION: This fuel delivery pipe has a housing 20 for installing a plurality of injectors 11 and a metallic cylinder 30 arranged inside 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. A deformation regulating bar 40 having side surfaces 41 and 41 regulating deformation of the metallic cylinder 30 within an elastic area, is arranged inside the metallic cylinder 30, in the fuel delivery pipe 10 constituted so as to absorb the fuel pressure pulsation by elastic deformation of the metallic cylinder 30. <P>COPYRIGHT: (C)2007,JPO&INPIT |
