DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front perspective view of a preferred embodiment of the present invention, in which a base (1) and a cloth foundation (2) are connected by a connecting member (3) and a connecting auxiliary member (4). By connecting the fabric base to the front, back, left and right directions of the house, it can exert a restoring force against the horizontal motion of the earthquake in all directions. This device has a restoring force of 1200 kg in all directions and one quarter of 300 kg in one direction. This drawing uses the pulling spring (25) with the hook (47) for hooking of FIG. 14 as the connecting member (3). When the connecting member (3) is apart from the basic connecting member, the connecting member (4) connects the connecting member (3) and the basic connecting member (21), and the connecting auxiliary member (4).
It is preferable to use a durable material such as a stainless wire, a stainless chain, a stainless chain, and a rubber material. The seismic isolation device (6) in the figure is disclosed in Japanese Patent Application Nos. 10-205743 and 3435.
It is a seismic isolation device such as No. 13. The mounting position of the base connector (7) and the base connector (45) may be displaced by about 30 cm to 60 cm due to the shaking of the earthquake. Attach in position.

FIG. 2 is a front perspective view of the embodiment of the present invention, in which the connecting member (3) shown in FIGS. 16 and 17 is provided between the pulling bar (19) and the cloth foundation (2). In this case, the connecting member (3) uses a pressing spring (36). The push-type spring shown in FIG. 15 has a long length with respect to the diameter, so that it is easily buckled by being pushed.
The pipe and the spring (36) are easily installed in the pipe of the outer cylinder (35) so that they can be easily expanded and contracted without buckling. FIG. 17 is a diagram in which a push spring is provided outside the inner cylinder and the outer cylinder. 16 or 17 of the base connecting member (21) and the connecting member (3) and the large pulling attachment (22) are connected by the right and left mounting holes (37) of the connecting member (3).

FIG. 3 shows an example of the present invention.
A mounting base connecting tool (29) is provided on the base side mounting base (28) slightly in the middle between the bases on the rising portion (24), and the connecting material (3) is used for hooking on the left and right ends of FIG. This is an embodiment in which a connecting member (3) of a rubber material (26) having a hole (46) is connected between a base (1) and a mounting base connector (29) of a base side mounting base (28). . Incidentally, the connecting member (3) of the pull type spring (25) in FIG. 14 can also be used. When using the connecting member (3) in FIG. 18, it is convenient to use the anchor bolt (10) horizontally for hooking the base, and in the case of the pull-type spring in FIG. 14, the anchor bolt or the connecting member (7). Can be used. When the distance between one end of the connecting member (3) and the base side or the base side mounting base (28) is longer than the connecting member (3), the connecting auxiliary member (4) is used and the base and the base side mounting base are used. (28)
To the mounting base connector (29). In this case, the push-type spring shown in FIG. 16 can be used by changing the mounting bracket capable of coping with the shaking of the horizontal earthquake. There are two types of springs: pull type and push type. The pull type has simple structure and low cost. Since the push mold has to consider the prevention of buckling, the cost is inevitably high. In long-term use, the push type is better to prevent "garbage" and "wood chips" from adhering to the spring.
