PROBLEM TO BE SOLVED: To provide construction machinery which makes possible a reduction in the number of parts and an improvement in assembly workability by the commonality of a leg body by a plurality of kinds of canopies. SOLUTION: An engagement projection 19 having a large-diameter step 19A and a small-diameter step 19B is provided to the right and left leg bodies 16, 17. The diameters of the large-diameter step 19A and the small-diameter step 19B become small in stages toward the upper part. Thus, each of the leg bodies 16, 17 can be mounted by engaging a large-diameter strut 20 of the two-strut type canopy 15 with the large-diameter step 19A of the engagement projection 19 from outside. Then small-diameter rear struts 32, 42 of a three-strut type canopy 31 and a four-strut type canopy 41 can be engaged with and attached to the small-diameter step 19B from outside. Because of this, since commonality of the leg bodies 16, 17 can be achieved by a plurality of kinds of canopies 15, 31, 41, the number of parts can be reduced and the assembly workability can be improved.
