摘要： The purpose of the present invention is to provide a fuel injection pump 1 wherein it is possible to easily position the second fuel supply path 21b of a housing 21 with the fuel supply hole 22a functioning as the fuel path of an insert piece 22, and to secure the insert piece 22 such that same does not rotate within the housing 21. The fuel injection pump 1 is provided with an electromagnetic spill valve 20, wherein the electromagnetic spill valve 20 is equipped with: the housing 21 on which an insert piece hole 21d is formed; the insert piece 22 which is formed in a roughly cylindrical shape having a valve seat 22b on the inner circumferential surface and which is inserted into the insert piece hole 21d in a detachable manner; a spill valve body 23 which is formed on the outer circumferential surface in a roughly columnar shape having a seal surface 23b capable of seating on the valve seat 22b, and which is inserted into the insert piece 22 in a slidable manner; and a securing means securing hole 21h, notched part 22h, securing screw 26 for securing the position of the insert piece in the periphery of the axial center relative to the insert piece hole 21d.
