That is, each of the legs 2 is formed of a thin elastic steel material, and has a diffused shape in which the legs 2 and 2 spread substantially evenly outward from the mutual centers of the legs 2 and 2. The pedestal 1 located above is stably supported. The diameter of each leg 2 is equal to that of each leg 2.
The device itself is adapted to exert an appropriate elastic force to firmly support various devices on the pedestal 1, and the length thereof can support the pedestal 1 at a predetermined height. Each leg 2 may be formed of an elastic steel material such as that of this embodiment, or an elastic body such as a leaf spring, a coil spring, a hard rubber, a soft resin, or the like, which can exert an appropriate elastic force. In that case, the same effect is obtained.

Each of the legs 2 has a diffusive shape by being bent in its entirety. That is, each of the legs 2 has a gentle bending shape, that is, a curved shape over substantially the entire area from the base portion 6 to the lower end portion, and by having such a curved shape, it has a diffusion shape. In this way, since the legs 2 are diffused by making the entire body bent, the legs 2 are gently curved to press the sliding body 3 with a substantially constant elastic force. Thus, a smooth sliding motion can be obtained.

In the present embodiment, the legs 2 are bent as a whole, but as shown in FIG. 8, only a part of the base 6 or the intermediate portion is bent. Therefore, it may be diffused. In this way, when each of the legs 2 is made into a diffused shape by partially bending it,
Almost all of the legs 2 can be made linear, and the legs 2 can be easily molded. Alternatively, as shown in FIG. 9, each leg 2 may be in a diffusive shape by making a substantially linear shape in its entirety. That is, each leg 2 itself may be linear, and the legs 2 and 2 may be diffused by attaching the leg 2 to the pedestal 1 in an outward direction.
