PROBLEM TO BE SOLVED: To perform vibration-proofing by a frequency variable system with vibrators consisting of a piezoelement and a piezoactuator on the outer surface of a support. SOLUTION: This spatial stabilizer is constituted so as to detect the frequencies of the vibration with the piezoelement (30a) and to drive the pizoactuator (30b) so that the vibration is suppressed by providing a plurality of the vibrators (30) consisting of the piezoelement (30a) and the piezoactuator (30b) on the outer surface (3a) of the support (3) holding the spatial stabilizer (100).
