PROBLEM TO BE SOLVED: To shorten the cylinder length, and reduce lowering side required thrust by rotatably pivotally fixing a link, on which the end part extending in the cab direction of an L-shaped lost motion link is slidably connected to an oblong hole, to a frame. SOLUTION: A cab C is rotatably installed on a tilt bracket 2 installed on a side rail 1 of a frame. The other end 7c of a link 7 having an oblong hole 7a on one end is rotatably pivotally fixed to a bracket 8 arranged on the rear side in the vicinity of the tilt bracket 2. An L-shaped lost motion link 10 is rotatably installed on a bracket 6 arranged on a floor panel 5. The lost motion link 10 rotatably connects the end part 10a to the rod side end part 15 of a tilt cylinder 16, and engages the end part 10b extending in the cab direction with the oblong hole 7a of the link 7. Thus, the tilt cylinder 16 can be shortened, and thrust to be generated by the tilt cylinder 16 can be reduced in an initial movement at tilt down time. |
