PROBLEM TO BE SOLVED: To provide a cover for a construction machine that can both protect against foreign matter intrusion and secure air vent opening area at a high level.SOLUTION: A bottom cover 20 as a cover for a construction machine includes: a cover body 21 fitted detachably to an opening formed in a bottom of a machine body of the construction machine; an air vent 22 opened on the cover body 21; and a plurality of angle louvers 23 arranged at intervals in the air vent 22. Each of the angle louvers 23 has a first-surface-side inclined part 32 formed on a first surface side of a bent part 31 in the center of the long-sized plate in a longitudinal direction and also has a second-surface-side inclined part 33 formed on a second surface side of the bent part 31 by bending a long-sized plate into an angle member shape at the bent part 31. Arrangement intervals of those angle louvers 23 are so set that a width of a projection opening between respective angle louvers projected at right angles to the louver array direction is smaller than a minimum gap between adjacent angle louvers. |
