Abstract
An insulator is implemented such that a lower structure member to be brought into contact with a floor surface allows an upper structure member on which a piano is placed to be suspended through a cantilever spring member and a first wire, and a second wire connects the upper structure member and the lower structure member to each other in the horizontal direction, and the insulator thus functions so as to maintain intrinsic sound generated by the piano by free vibration in pendulum motion using the upper end of the first wire as a pivot, and richness of the sound is enhanced and transmission to a floor surface is inhibited, and, further, vibration caused by a key and a pedal being operated by a performer is reduced by elasticity of the cantilever spring member and the tensile force that acts on any of the second wires, and the performer does not feel uncomfortable with the operation.
