PROBLEM TO BE SOLVED: To provide a deflector and a fuel injection pump capable of effectively suppressing erosion generated caused by cavitation generated within fuel discharged from a plunger barrel to an inlet/outlet fuel chamber in the fuel injection pump of a diesel engine or others.SOLUTION: In a fuel injection pump 1 having a cylindrical plunger barrel 2 formed by an inlet/outlet port 11 passing through, a plunger 3 defining a plunger chamber 21 along with the plunger barrel 2, and an inlet/outlet fuel chamber 4, characterized in that fuel supply and fuel discharge are carried out by opening and closing the inlet/outlet port 11 by a reed 31 by the reciprocating motion of the plunger 3, a deflector 40 is arranged to in the inlet/outlet port 11, a step is formed in the plunger chamber 21 side more than the reed in the plunger 3, and an inclining part 34 of a step angle of ≥45° and ≤70° is formed in the step. |
