To provide an oiling pump storage box which can prevent floor side from being stained by oil droplets dropped after supplying kerosene to a domestic kerosene space heater and ensure a storing space for the oiling pump.

A pump storage box 4 whose lower end part is formed at a bottomed cylindrical sump capsule 5 detachably-screwed and fixed, is fitted at the side part of a kerosene space heater. The sump capsule 5 is constituted of oilproof transparent or translucent resin material, and an annular body 7 whose outer periphery is formed with a threaded part 5b is fixed on the lower side part of the pump storage box 4, and screwed and fixed on a threaded part 5a formed at the inward upper edge part of the sump capsule 5, and is provided with a small-diameter cylindrical body 4b for communicating the pump storage box 4 with the sump capsule 5 by penetrating it through the center of the annular body 7. The inside diameter length of the cylindrical body 4b is formed so as to be smaller than the diameter length of the suction opening or discharging opening of the oiling pump 6.
