の先端は振動台６の一部に固定されている。Fig. 2 shows a side view of the horizontal type of the soft type dynamic balancer according to the first embodiment of the present invention, and Fig. 3 is a partial sectional view thereof.4) In Fig. 2, 6 is a rotating body. 6, a support frame γ supports the vibration table 5 via leaf springs 8a and 8b, and 9a and 9b are sandwiched between the vibration table 6 and the support frame 7, as shown in FIG. It is rubber that is held under pressure by the bolt 1Q, and is prevented from falling off by the hole 12 of the leaf spring retainer 11. Further, a pickup 13 for detecting vibration is attached to one side of the support frame 7, and a connecting rod 14
The tip of the vibration table 6 is fixed to a part of the vibration table 6.

By applying pressure at 0a and 10bK, the horizontal vibration of the vibration table 5 is suppressed. As a result, the natural frequency ω of the vibrating string increases and approaches the constant rotational frequency ω.
