<p>PROBLEM TO BE SOLVED: To prevent color transfer to a floor, to attain vibration control and base isolation by using an elastic material and a high strength material, to simplify a structure with good appearance because a reinforcing member such as an aggregate is not required to prevent deformation, to secure smooth slide on the floor and mobility when moved, and to preclude coming-off at the time of moving since respective members are formed integrally. SOLUTION: This receiver is composed of a caster receiver main body 5 having a recess 5a for inserting a lower part of a caster of a piano and formed with a hard synthetic rubber, a bottom plate 6 engaged with the lower part of the main body 5 and formed with ABS resin (acrylonitrile-butadiene-stylene copolymer) of a hard synthetic resin, and a hard fibrous material 7 bonded to the bottom of the bottom plate 6.</p> |
