Claims

[Scope of utility model registration request]

Center rubber spring 1 and torsion rubber springs 2 and 3 on both sides
are connected in series around a common square shaft 4, the square shaft is supported by both side walls 16 of the frame 15, and a link arm 8 is fixed to each outer frame 7 of the rubber springs 2 and 3. A protrusion plate 9 extending horizontally is fixed to one surface of the outer frame 7 of the central rubber spring 1, and an upper surface 11 is provided on the bottom surface of the frame below the central rubber spring 1, which is inclined with respect to the axis of the square shaft. , and a wedge-shaped block 13 that is moved by a threaded connection of a threaded rod with a knob 17 passing through the side wall of the frame is disposed, and a recess 18 on the bottom surface of the protruding plate 9 is disposed between the protruding plate 9 and the bracket 13. A hard ball 14 is provided, a part of which is rotatably fitted into the block and comes into contact with the block inclined surface 11. Rotation of the threaded rod causes the rod-shaped rubber 6 of each clamping spring to be elastically deformed, thereby causing the spring system to rotate. A strength adjustment mechanism of twin rubber springs whose strength can be adjusted.
