Patent ID: 8398002

Claim:
A fuel injection device comprising: a nozzle configured to inject high pressure fuel from injection holes; a pressure control unit configured to control operation of the nozzle in accordance with an electrical signal input from an exterior; a body having therein a lead wire hole through which two lead wires connected to the pressure control portion are introduced to the exterior, the lead wire hole having a bend defined at an intermediate position along a length thereof; a first guide member having therein a pair of first guide bores extending in an axial direction of the first guide member, the first guide member being inserted into the lead wire hole from one end of the lead wire hole; a second guide member having therein a pair of second guide bores extending in an axial direction of the second guide member, the second guide member being inserted into the lead wire hole from the other end of the lead wire hole; a first partition member provided in the first guide member to partition the first guide bores from each other, the first partition member protruding from one end portion of the first guide member to define a protruding part of the first guide member; and a second partition member provided in the second guide member to partition the second guide bores from each other, the second partition member being recessed from one end portion of the second guide member to define a recess portion of the second guide member, wherein the protruding part of the first guide member is fitted with the recess portion of the second guide member, so that the one end of the first guide member contacts the one end of the second guide member at said bend defined at said intermediate position along the length of said lead wire hole, such that said axial direction of the first guide member is inclined with respect to said axial direction of the second guide member, and the two lead wires connected to the pressure control portion protrude toward the exterior respectively via the first and second guide bores the first and second guide members.
