The timing belt 13 is looped around the protrusion 13 and the protrusion 14 is provided at the center of the belt 13. The limit switches 15 and 15 are fixed to the machine box 2 on the left and right sides of the protrusion 14, and the protrusion 14 slides to the right or left. Thus, one of the limit switches 15 and 15 can be operated (closed), whereby the lateral inclination detection device 6 of the machine case 2 can be formed.

Further, right and left wire rope winding winches 3 and 3'are provided at the left and right ends of the machine box 2, and the tip portions 4 "and 4" of the left and right winding wire ropes 4 and 4'are outside the front. The left and right take-up wire ropes 4 and 4 ′ are supported and fixed to support metal fittings 9 and 9 provided at both ends of the roof of the wall surface, and the left and right winding wire ropes 4 and 4 ′ are stretched on the left and right outer slants of the machine box 2 to provide three points Be hung.

As shown by the dotted line in FIG. 1, when the roof car 8 is moved to the corner of the roof and the machine case 2 is suspended at the end of the front outer wall surface 5 ', the other of the left and right winding wire ropes 4, 4'is The machine case 2 can be protected from a gust by supporting and fixing the tip portion 4 ″ to the roof support fitting 9 of the side outer wall surface 5 ″.

The tilt detection signal 6'from the limit switches 15 and 15 excites the left and right relays in the control device 7 and closes the relay contacts so that the winch 3 or 3'on the right or left side is passed through an encoder. The machine box 2 can be automatically returned to the horizontal position by rotating and winding or unwinding the right or left wire rope 4 or 4 '.
