PROBLEM TO BE SOLVED: To provide a work machine enabling a dust-proof member to be easily fitted to a suction port as necessary.SOLUTION: A work machine includes: a machine body; a cover fitted to the machine body and having a suction port; and a dust-proof member fitted to the suction port. The dust-proof member includes: a plate portion having a plurality of through holes; and lock portions each projecting from the peripheral edge of the plate portion and bent or curved to abut on a surface on the side opposite to the side where the plate portion is arranged in an edge portion of the suction port. The plate portion covers the suction port from the outer side of the machine body. Each of the lock portions includes: a projection portion projecting from the peripheral edge of the plate portion to the inner side of the machine body; and an abutment portion bent or curved from the projection portion to abut on the surface on the inner side of the edge portion.SELECTED DRAWING: Figure 7
