Claims

[Claims for Utility Model Registration] (1> In order to prevent horizontal vibration of an object installed on a fixed stand, relative horizontal movement between the above object and the fixed stand is allowed. A rolling member is interposed therein, and an upper concave curved receiver for receiving the rolling member is disposed on the lower side of the object, and a lower concave curved receiver for receiving the rolling member is disposed above the fixed base. is provided with a non-linear characteristic such that the natural frequency in the horizontal vibration becomes high when the rolling member is rolling on each peripheral edge of the upper concave curved receiver and the lower concave curved receiver. Therefore, an edge having a radius of curvature smaller than the radius of curvature of the upper concave curved receiver and the lower concave curved receiver is formed on each peripheral edge of the upper concave curved receiver and the lower concave curved receiver. A horizontal dynamic vibration isolator characterized by: (2) The rolling member is formed in a cylindrical or spherical shape, and the upper concave curved receiving portion and the lower concave curved receiving portion have a radius R1 larger than that of the rolling member. The horizontal movement guard according to claim 1 of the utility model registration claim, wherein the edge portion is formed into a cylindrical shape with a radius R2 smaller than the radius R□ of the concave curved receiving portion. A shaking device. (3) The rolling member is formed into a spherical shape, and
The upper concave curved receiving portion and the lower concave curved receiving portion are each formed into a spherical shape with a radius r larger than that of the rolling member, and the edge portion has a radius smaller than the radius r□ of the concave curved receiving portion. The horizontal dynamic vibration isolator according to claim 1, which is formed into a spherical shape of r2.
