CONSTITUTION:The first bracket 3 secured to a power unit is fixed to the first frame 4, and the second bracket 6 secured to a car body is fixed to the second frame 7. An auxiliary frame 50 is disposed between the first frame 4 and the second frame 7. The auxiliary frame 50 can be moved relative to the second frame 7 by adjusting the screw-in of a bolt 63 forming adjusting means 60, so as to adjust stopper clearance delta1, delta2 between stoppers 11, 12 and an elastic substance 8.
