摘要：
An earthquake-proof leg support structure (10) of an electronic apparatus comprising a leg (12) vertically downwardly extending from the outer case (1) and a dish-shaped leg support seat (20) to receive the leg (12). The leg support seat (20) includes a metal element (28) having an upper surface (22) over which the leg (12) slides and a peripheral flange (24) against which the leg (12) abuts, and a plastic liner (30) having a lower flat smooth surface (26) which is slidable on the floor. The lower end surface (14) of the leg is of a convex spherical shape and the upper surface (22) of the leg support seat includes a central surface portion (22a) of a concave spherical shape and a cone-shaped slope portion (22b) arranged around and tangential to the central surface portion, with the radius of curvature of the leg (12) being smaller than that of the upper surface (22) of the leg support seat (20 ).
