Abstract: A frame structure includes a pair of sideboards facing each other, each sideboard having an inner surface provided with a plurality of support grooves for receiving and supporting panel plates, a first joint for fixing one of the pair of sideboards to a base and a second joint for fixing the other of the pair of sideboards to the base and provided with a movement-effecting mechanism. The first and second joints have formed on the facing inner surfaces thereof at substantially the same height steps for contacting side surfaces of the panel plates and supporting the panel plates. At least one of the steps has a surface for contacting at one side surface of one of the panel plates prior to panel plates being received in the plurality of support grooves in order to set a distance between end surfaces of opposed ones of the plurality of support grooves equal to a sum of the width of the panel plates received in and supported by the plurality of support grooves and a predetermined clearance.

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 leg10 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.
