PROBLEM TO BE SOLVED: To prevent leakage of a laser beam and undesirable vibration sound. SOLUTION: A shield 16 is lowered from the upper part of a loader chassis 2, each guide hole 25 is fit into each positioning pin 24 to put the shield 16 on both side panels 2a of the loader chassis 2. The shield 16 is slid forward (a) along the each positioning pin 24. Each columnar pin 22 is engaged with each blade 23 elastically by pushing down a pullout stop 23c of each blade 23 with each columnar pin 22. Thus, the shield 16 is pressed to the both side panels 2a of the loader chassis 2 for elastic engagement, and the front edge 16A of the shield 16 is moved under a crossbeam 12.
