PROBLEM TO BE SOLVED: To provide a shock buffering device having high vibration controllable effect in a simple, compact, and light-weighted structure with a low cost. SOLUTION: The shock buffering device comprises a supporting portion 1 combined with a hull 100, an installing portion 2 installed in a deck 200, a spring 3, and a damper 4 and the like. The supporting portion 1 and one side 41 of a buffering portion, and the installing portion 2 and other side 42 of the buffering portion are combined, respectively. Further, when a face 1a and a first one side 31a, a face 2a and a first other side 32a, a face 1b and a second other side 32b, and a face 2b and a second one side 31b are respectively kept into contact each other between the supporting portion and the spring, initial load F0 is generated in the spring portion. |
