PROBLEM TO BE SOLVED: To solve problems in a conventional injection pump that as foreign matter such as fine iron dust and the like are often mixed in oil droplet of a lubricant splashed up from a lower part in a device, and flows inside the pump through an air hole formed on a sidewall, which causes the internal fracture, the improper sliding and the improper operation. SOLUTION: An eaves-shaped oil scattering-prevention plate 9 is fastened and fixed to the sidewall 6 of the injection pump 3 by means of a mounting bolt 8 utilizing the air hole 7. The oil scattering-prevention plate 9 prevents the scattering of the oil droplet splashed up from the lower side, and the mounting bolt 8 is provided with an air hole 7a on its central part for circulating the air.
