SOLUTION: A machine body frame 51 of a lower structure 23 is provided with a soil removing blade 53 in a vertically movable manner through an arm part 52, and the expansible blade cylinder 54 moving the blade 53 vertically is provided between the blade 53 and the machine body frame 51. A cylinder guard 55 is provided along the upper part of the blade cylinder 54. Hoses 56, 57 for supplying/discharging an operating fluid to/from the blade cylinder 54 are disposed between the machine body frame 51 and the blade cylinder 54 on the lower side of the cylinder guard 55. The longer hose 56 connected to the cylinder head side is restricted to the lower side of the cylinder guard 55 by a hook 58 serving as a restricting body mounted to the lower face of one side part of the cylinder guard 55.
