Abstract
An equipment adjusting leg is provided which is lightweight and which can achieve cost reduction without decreasing impact-resistant strength. The impact-resistant strength is secured and the light weight is achieved by the structure of the equipment adjusting leg, which comprises: a leg 10 which is provided in the lower part of an external frame of the equipment in a manner capable of moving up and down, and of which lower part is formed as a ground contact part 16 and of which upper part is formed as a sliding shaft 17 with a concavo-convex part 18 like, for example, a screw, provided around the periphery of the sliding shaft 17; an element for locking the up-and-down movements of the leg; and an element for releasing the lock; wherein the sliding shaft 17 of the leg 10 is constructed by using a resin with excellent mechanical strength, such as polycarbonate, to construct a peripheral part, and by using an elongated metallic member (a metal shaft 24) as a core.
