PROBLEM TO BE SOLVED: To solve the problem that even in a structure which uses a vibration-proof device to make compatible both a vibration-proof function for a building and an earthquake-proof function for an indoor unit and allows the vibration-proof device to be suspended vertically with ceiling suspension bolts and further supported and fixed obliquely using oblique support materials so as to stop horizontal and vertical shakes, shaking easily occurs horizontally and moves up and down if applied with a horizontal external force and a vertical external force due to an earthquake.SOLUTION: A ceiling suspension type indoor unit for air conditioning includes an indoor unit body 1, an upper suspension bolt 3 suspended from the ceiling 2 in a room to be air-conditioned, a lower suspension bolt 6 fitted to the indoor unit body 1, a vibration compensating mechanism 5 interposed between the upper suspension bolt 3 and lower suspension bolt 6 so as to attenuate vibrations from the indoor unit body 1, and a lateral shake suppressing mechanism 20 arranged at the indoor unit body 1 above the vibration compensating mechanism 5 so as to suppress lateral shakes of the indoor unit body 1. |
