PURPOSE: A noise reducing structure for an injection pump is provided to prevent noise generated in the injection pump from being transferred to the exterior by attaching a noiseproof cover on the outside of the injection pump. CONSTITUTION: A noiseproof cover(70) is attached on the outside of an injection pump(50) so as to prevent noise generated in the injection pump(50) from being transferred to the exterior. The noiseproof cover(70) includes an outer cover(71) and an insulator(72) formed at an inner portion of the outer cover(71). The insulator(72) is made of EDPM. A coupling portion(73) is formed at a predetermined portion of the outer cover(71) so as to couple the noiseproof cover(70) to the injection pump(50). The coupling portion(73) is made of rubber. A bolt hole(51) is formed at the injection pump(50) to attach the noiseproof cover(70).
