ABSTRACT:
A power plant mounting bush according to the present invention includes a rubber insulator 16 having a pair of holes 13 opposing each other from the center of an inner pipe 11, wherein the rubber insulator 16 is installed at a circular bracket 25 with a bearing 20 therebetween so that the rubber insulator 16 can be freely revolved in the bracket 25 and a plurality of electromagnets 26 are disposed along an inner surface of the bracket 25 each disposed at predetermined spaces with a plurality of electromagnets 15 also formed at an outer pipe 14 of the rubber insulator 16, whereby a control unit 30 selectively applies electric current to the electromagnets 15 and 26 so that attracting force or repulsing force is selectively acted between the electromagnets 15 of the rubber insulator 16 and the electromagnets 26 of the bracket 25 in order to rotate the rubber insulator 16 by a predetermined angle in the bracket 25.
