Claim:
A leg-portion attachment structure for movably supporting a main body of an apparatus, said structure comprising: a plurality of casters movable on a floor surface; a metal support member having a substantially quadrilateral outer periphery and an upper surface on which the main body is mounted; and a metal attachment plate provided at least at one of two opposite sides on a lower surface of the support member so as to form a first gap between the main body and the attachment plate, the attachment plate including a caster attachment portion formed on two end sides in a side direction so that one of the plurality of casters is firmly attached, a first elastically deformable bent portion formed by bending of an outer edge in the side direction of the caster attachment portion at a predetermined angle, a first coupling portion that is formed by further outward bending of an edge of the first bent portion and is firmly attached to the support member, a second elastically deformable. bent portion formed by bending of an inner edge in the side direction of the caster attachment portion at a predetermined angle, and a connecting portion formed between two of the second bent portions to have, in a direction orthogonal to the side direction, a free end free from being firmly attached to the support member, wherein a second gap is provided between the first elastically deformable bent portion and the support member.
