ラケット５に内筒３を取付けたものである。(Prior Art) Conventionally, vibrations caused by sudden forces during operation of an engine mounted on a vehicle have been reduced by an engine mount device that attaches the engine body via a mount member. As shown in FIG. 6, the mount member has an inner cylinder 3 suspended from a mount rubber 2 inside an outer cylinder l, and as shown in FIG. The inner cylinder 3 is attached to the vehicle body side bracket 5.

地の改善がなされている。第７図は荷重による内情の変
位を示したばね特性である。Further, the mount member has a hollowed out portion 6 (see FIG. 6) formed on one side of the inner cylinder 3 at the lower side to facilitate deformation of the mount rubber 2 on which the central inner cylinder 3 is suspended. Therefore, when the engine operates and vibrations occur, a load is applied to the inner cylinder 3 through the mount rubber 2, and the mount rubber 2 deforms and the position of the inner cylinder 3 is displaced, so the vibrations caused by the engine are absorbed and the vehicle body The vibrations transmitted to the vehicle are reduced, which improves ride comfort. FIG. 7 shows the spring characteristics showing internal displacement due to load.
なお、マウント部材の支持７段は実願昭８３−１２８０
８４号にも開示されている。In addition, the seven stages of support for the mount member are based on Utility Application 1280-1983.
It is also disclosed in No. 84.

、 ２１ 。In the engine mount device configured as described above, when a load is applied in the direction of the arrow shown in FIG. 1 due to the operation of the engine 7, the connecting rod 18 tilts to follow the load. In this case, when a downward load is applied, as shown in FIG. 4, the connecting rod 18 moves downward to the left in the drawing, and the center of rotation C is to the right of the position of the central mount member 12. Moreover, as the connecting rod 18 inclines, each clearance Kl
, 2 and 3 change due to the displacement of the inner cylinders 20, 21, and 22, and the mount rubber 18 contacts or presses the stopper rubber 23, so that the inner cylinder 2G against the load is sequentially changed.

でばね定数が小さくなる。The displacement of 22 changes, resulting in a spring characteristic as shown in FIG. Clearance between 0 and P is K1 * K2 to 3
The spring constant is large due to this influence, but after the second point, the mount rubber 13 and the stopper rubber 23 come into contact with or are pressed, so the spring constant becomes small.
