PROBLEM TO BE SOLVED: To provide an adjustable leg easily performing assembly in an equipment bottom plate by fitting with a slight elasticity characteristic utilized of a case itself to reduce the number of part items. SOLUTION: A case 1 is formed by a mass of hard synthetic resin molded article having slight elasticity, a support protruded edge 5 and an elastic check pawl 8 are provided in an external surface of both parallel side walls 4 of the case 1. A lock unit 20 is supported by a horizontal shaft 21 in the case 1, to be provided with screw parts 22a, 22b by point symmetry around the horizontal shaft 21. By a push button 50 fitted capable of sliding to the case 1, the screw parts 22a, 22b of the lock unit 20 are separated from a screw bar 30 of a leg unit 31 against energizing of a spring 40.
