PURPOSE: To naturally and stably suspend a suspended object without causing its deformation and the deviation of the relative positions of built-in devices.

CONSTITUTION: A fixed suspension 13 having a coupling guide section 14 with a required length is fitted on a base 10 having a suspension section 11 suspending a suspended object with a suspending object, and a sliding suspension 15 having a suspending through hole 17 is coupled with the coupling guide section 14 of the fixed suspension 13 and guided. A bolt 22 supported at both end sections is screwed to the sliding suspension 15, a handle device 26 rotating a shaft 23 is fitted to the shaft 23 provided at one end of the bolt 22, and reduction gears 31 and a motor 32 separably coupled with the other shaft 27 via a coupling are fitted on the base 10.
