<P>PROBLEM TO BE SOLVED: To provide a supporting device of a fuel injection valve capable of obtaining an alignment mechanism simply and at low cost without performing any special work. <P>SOLUTION: The supporting device of a fuel injection valve is formed by fitting a fuel distribution pipe 38 to the outer circumference of a fuel inlet tube 7 at the rear end of the fuel injection valve I with a front end nozzle tube 3a fit to the attaching hole 1b of an engine E, and by setting the alignment mechanism 41 that holds the fuel injection valve I in the axial direction cooperating with the fuel distribution pipe 38 between the engine E and the fuel injection valve I, and a supporting hole 40 that has a backward step 40b is provided at the engine E. The alignment mechanism 41 is composed of a ring-like ring holder 42 housed in the supporting hole 40 so as to be born on the backward step 40b, an annular support ring 43 with a circular cross section and held to a ring-like recessed part 42a opened backwardly to an inner periphery of the ring holder 42, and a frontward conical face 44a formed at the fuel injection valve I so as to be in contact with the support ring 43. <P>COPYRIGHT: (C)2012,JPO&INPIT |
