れている。1, 2 and 3 show an example of the vibration suppressing unit of the present invention, in which the guide 10 implanted in the bracket 7 is attached to the guide rod 9 fixed to the protrusion 8a of the bracket 8. It is mounted slidably. Therefore, the bracket 7 and the bracket 8 are relatively movable up and down. The bracket 7 and the bracket 8 are connected by a suspension 6 provided between a protrusion 7a of the bracket 7 and a protrusion 8b of the bracket 8, and the bracket 7 is held in a suspended state with respect to the bracket 8. The bracket 7 is provided with a hole so that the counterweight 5 can be attached and detached by a bolt,
A hole is formed in the bracket 8 so that it can be attached to and detached from the vehicle body 1. FIG. 3 shows an example of the structure of the suspension 6, and the rod side circuit of the cylinder 6 is connected to an accumulator 13 which is a spring via a variable throttle valve 14 which is a damper.

１図（ａ），（ｂ）の如く本考案による振動抑制装置付
車両に変更できる。The counterweight mounting bolt 5a is removed from the vehicle without the conventional vibration suppression device shown in FIGS. 4 (a) and 4 (b), and the vibration suppression unit of the present invention is mounted between the counterweight 5 and the vehicle body by the bolt 5a. And 1a, it can be changed to the vehicle with the vibration suppressing device according to the present invention as shown in FIGS. 1 (a) and 1 (b).
車体１がバウンシングあるいはピツチング振動を起こし
た場合、副振動系となるカウンタウエイト５が逆位相の
上下振動を起こし車体振動を減少させる。When the vehicle body 1 causes bouncing or pitching vibration, the counterweight 5, which is a sub-vibration system, causes vertical vibrations of opposite phase to reduce the vehicle vibration.
サスペンシヨン６の特性は、アキユムレータ13及び可変
絞り弁14により調整できる。The characteristics of the suspension 6 can be adjusted by the accumulator 13 and the variable throttle valve 14.
