PROBLEM TO BE SOLVED: To provide a vibration proofing structure of a soft nodal structure capable of realizing a soft nodal earthquake proofing structure which has high damping characteristic against vibration to a structure of a soft nodal structure supporting a post-beam joint part of a post and a structure with a pin. SOLUTION: The structure of the soft nodal structure in which the post 1 and the upper structure 2 are joined with the pin through a pin joint part 4, is composed of a projecting beam 5 fitted to the tip part of the post 1 and an umbrella type toggle mechanism 6 installed at tip parts on both sides of the projecting beam 5. The displacement amount of the tip part of the projecting beam 5 is amplified by the umbrella type toggle mechanism 6, and the amplified displacement amount is the stroke of a shock absorbing member 64, so that a high-damping soft nodal earthquake proofing structure can be realized.
