PROBLEM TO BE SOLVED: To facilitate passing to a driver's seat by forming a part being a rear side rising wall of a step in a substantially flush shape without a recess-projection. SOLUTION: A support frame 4 of a rectangular shape in a plan view having a column 4, is arranged in a rear part of a revolving base 2 by straddling an engine 3. The driver's seat 12 is mounted on an upper part of this support frame 4. A right work operation device 15 is fixed to a right side part of the support frame 4. A left work operation device 14 is arranged in a left side part so that an attitude can be freely changed to an operation attitude and a retreat attitude. A radiator 5 is arranged on the left side of the engine 3. A side cover 8 for covering the radiator 5 is arranged in a left side part of the support frame 4. A front face of the side cover 8 and a front face 76a of the left work operation device 14 of the retreat attitude, are arranged so as to become substantially flush with a fixing cover 6 arranged in front of the support frame 4. The step 45 is formed on the front side of the fixing cover 6 and the side cover 8. COPYRIGHT: (C)2006,JPO&NCIPI
