PURPOSE: To securely prevent fall of a work machine even in the case where the support ground collapses by providing fluid tubes between lateral members of outriggers and the ground.
CONSTITUTION: Outriggers 11 comprising lateral members 13 and vertical members 15 are protruded outward from plural positions at an interval around a work machine 1, and lower ends of the vertical members 15 of the outriggers 11 are put to the ground G for fixing the work machine 1 to perform various types of work. At this time, fluid tubes 21 having a height to a size between the lateral member 13 and the ground G are provided between the lateral members 13 and the ground G. The fluid tubes 21 can thus be fit to the form of the ground G if the ground G has irregularities, and the fluid tubes 21 can be folded by discharging air, thereby installation or removal work can also be performed easily.
