And stored in a state of being turned (turned) to the rear of the vehicle body 2 by the turntable 4. At this time, the arm member 30 of the lighting device 20 is stored in a state of swinging substantially vertically downward with respect to the leveling bracket 21 (the boom 5 in the retracted state).

  At this time, in the present embodiment, the leveling mechanism 25 keeps the inclination angle of the leveling bracket 21 with respect to the vehicle body 2 constant regardless of the up-and-down movement of the boom 5, and the angle holding mechanism 50 makes the leveling bracket of the illumination holding member 40. The inclination angle with respect to 21 is kept constant regardless of the swing of the arm member 30. Therefore, the inclination angle of the illumination holding member 40 with respect to the vehicle body 2 is kept constant regardless of the raising / lowering movement of the boom 5 and the swinging of the arm member 30, so that the lighting holding member 40 moves up and down and the arm member 30 swings. Regardless of movement, the vehicle body 2 extends in a substantially vertical direction. Therefore, the illumination holding member 40 is stored in the rear part of the vehicle body 2 while extending in a substantially vertical direction with respect to the vehicle body 2, and the rear side of the vehicle body 2 is adjusted by the lamp 45 without adjusting the orientation of the illumination holding member 40 and the lamp 45.

The illumination holding member 40 holding the lamp 45 is displaced to a desired position. Then, with the illumination holding member 40 being displaced to a desired position in this way, illumination is performed by turning on the lamp 45.

  In addition, with the boom 5 stopped, the upper leveling cylinder 26 is expanded and contracted regardless of the operation of the lower leveling cylinder 27 to swing the leveling bracket 21 in the vertical direction. It is possible to swing the illumination holding member 40 whose inclination angle is kept constant in the vertical direction. Thereby, the up-and-down direction of illumination can be changed easily.
