PURPOSE: To aim at a considerable reduction in a solid propagation sound, by supporting an independently constituted living quarter room suspensorily on a living quarter constituting part being partitively formed with vertical and horizontal members via aling member.
CONSTITUTION: A living quarter room 14 being constituted separately from a living quarter by peripheral walls 13 is housed inside the living quarter made up of living quarter constituting members such as a vertical member 11 and a horizontal member 12 or the like, while the living quarter room 14 is suspended from the vertical member 11 via a sling member. As the sling member, an L- shaped member 15 attached to the vertical member 11 and an inverted L-shaped member 16 attached to the peripheral walls 13 of the living quarter room 14 are engaged with each other via a vibro-siolating element 17 of rubber or the like. In addition, a stopper element 20 of rubber or the like is additionally installed whereby a large vibration is limited to the smallest possible extent. With this constitution, a solid propagation sound out of a vibration generator part is thus effectively reducible.
