PROBLEM TO BE SOLVED: To stabilize the mounting state of a muffler cover for shielding an operator, etc., from the muffler and improve reliability by installing the muffler cover in a counter weight. SOLUTION: On a lower traveling body 1, there is mounted an upper swing body 2 provided with a cab box 5, the counter weight 6, an engine 7, etc. The muffler cover 20 for covering the rear side of the muffler 13, which is mounted on the top surface part 6A of the counter weight 6, prevents the operator from accidentally contacting the high-temperature muffler 13, for example, in the ease of the replacing operation for an oil filter 12 and the like. Consequently, vibrations from the engine 7 can be prevented from being transmitted to the muffler cover 20, which can be formed as a small and lightweight type, and the prevention of the play, deformation, etc., of the muffler cover 20 enables the reliability to be improved.
