PROBLEM TO BE SOLVED: To solve the problem on a conventional fuel injection pump having only one accumulator that pulsation cannot be inhibited in all ranges from a low rotation region to a high rotation region and the suction efficiency of a fuel is lowered in medium to high rotation regions, resulting in a less or unstable injection amount of fuel or impossible fuel injection. SOLUTION: This distribution type fuel injection pump 1 having a plunger 7 to be slid vertically by a cam 5 and a distribution shaft 9 arranged in parallel thereto for distributing a fuel to cylinders comprises a plurality of accumulators 19, 20 provided in a fuel gallery 43 for damping pulsation pressure in such a manner that the damping characteristics of the accumulators 19, 20 are set to be mutually differentiated depending on the operating conditions of the fuel injection pump 1.
