The arcuate concave outer surface 9 is slidably and rotatably contacted in the R direction with the cross-sectional arc outer surface 9 and the cross-sectional arc convex outer surface 7 of the support body 8 centered on the center O1, and on the other hand, The flat surface 10 of the floor panel 2 is rotatably contacted in the R direction centering on the center O2 with a circular arc convex outer surface 11 having a center of curvature, that is, the center O2, that is, rollingly freely centered on the center O2 and with the support body 8 The load of the vertical direction V of the daily appliance 3 that is interposed between the support bodies 8 is also taken.

The support body 8 has a cylindrical body 23 having a screw portion 21 at an upper portion and a bee waist portion 22 at a lower portion, and a partial ball portion 24 integrally formed on the bee waist portion 22 of the body 23; The nut 25 of the screw portion 21 is screwed to the mounting portion 6 in the screw portion 21 with respect to the vertical direction V. The cross-sectional arc convex outer surface 7 includes a partial spherical portion 24 as a part of the spherical surface. Part of the spherical convex surface 26.

The rotating body 12 includes: a circular arc concave outer surface 9 including a partial spherical concave surface 31 as a part of the spherical surface; a cross-sectional circular convex outer surface 11 including a partial spherical convex surface 32 as a part of the spherical surface; The truncated polygonal outer surface, in this case the frustoconical outer surface 33, is attached to the cross-sectional arcuate outer surface 9 on one side and to the arcuate outer surface 11 on the other side and includes a truncation The outer surface of the head cone or the outer surface of the truncated quadrangular pyramid; and the outer surface of the convex outer surface 7 of the support body 8 is the center of curvature of the convex outer surface 7 of the cross section of the support body 8 and is also the rotating body 12 The center O1 of the center of curvature of the concave outer surface 9 of the cross section is centered and rotatable in the R direction; the center of curvature of the outer surface 11 of the circular arc convex surface of the rotating body 12 is the stationary state of the anti-vibration support device 1 (Fig. In the state shown in Fig. 1, the center of curvature of the concave outer surface 9 with respect to the circular arc of the rotating body 12, that is, the center O1 is eccentric to the core in the vertical direction V by the eccentricity δ, and is located above the side of the daily appliance 3; The center of curvature of the outer surface 7 of the arcuate convex surface of 8 is the center O 1 and the center of curvature of the arcuate convex outer surface 11 of the rotating body 12, that is, the center O2 in the static state of the anti-vibration support device 1, is located on the same lead line 35; the curved convex outer surface 11 of the rotating body 12 has a comparative The position of the arcuate convex outer surface 11 of the anti-vibration support device 1 in contact with the flat surface 10 of the floor 2 in a stationary state The distance d between the point P and the center O1 is larger than the radius of curvature r2, and the eccentricity δ becomes r2-d.

In the case where a plurality of at least three of the above-described shock-proof support devices 1 disposed at the lower portion of the case 4 outside the daily tool 3 are in a state in which the vibration caused by the earthquake in the horizontal direction H is not applied to the floor 2, The static state is shown, and the load of the daily appliance 3 is shared on the floor 2 to support the daily appliance 3; when the vibration of the horizontal direction H caused by the earthquake is applied to the floor 2, the rotating body 12 of each anti-vibration support device 1 is as shown in the figure As shown in Fig. 2, the flat surface 10 of the floor panel 2 is rotated in the R direction with respect to the partial spherical portion 24 with respect to the center O1. By this rotation, each of the anti-vibration support devices 1 blocks the horizontal direction H applied to the floor panel 2. The vibration is transmitted to the daily tool 3, and the shockproof support of the daily appliance 3, on the other hand, the curvature radius r2 and the distance d of the cross-sectional convex outer surface 11 caused by the eccentricity δ of the center O1 and the center O2 are different.

Sin θ (wherein W is a load applied to the rotating body 12, δ is an eccentric amount δ=(r2-d), and a rotation angle of the θ-based rotating body 12), and the recovery torque M is used to have a period T After the vibration of the pendulum body 12 in the horizontal direction H caused by the earthquake disappears, the sliding friction of the concave outer surface 9 with respect to the circular arc convex outer surface 7 and the rotating body 12 relative to the floor 2 The rolling friction of the flat surface 10 causes the convergence of the pendulum motion caused by the dissipation of the vibration energy to return to the rotational position at the time of the stationary state, thereby returning the daily appliance 3 to the initial position before the earthquake shock.

The period T of the pendulum motion of the rotating body 12 is expressed by the formula (1). When θ is small, the result is θ/sin θ ≒ 1, and the period T is expressed by the formula (2). If the difference between the radius of curvature r2 of the outer surface 11 and the distance d, that is, the eccentricity δ (= r2-d) is smaller, the smaller the period T is, the larger the eccentricity δ (= r2-d) is. The larger the period T is, the shorter.
