以下、図面に示す実施例を参照しながら本考案を説明す
る。The present invention will be described below with reference to embodiments shown in the drawings.

スリット2,3を各々設け、かつ上下つまりY方向に互
いに対称な形状のスリット4,4を各々設けた構成を有
する。As shown in one embodiment in FIG. 2, the torque rod insulator 1 is made of a circular elastic material (for example, rubber), and is provided with slits 2 and 3 that are asymmetrical to each other in the left and right directions, that is, in the X' and X directions. , and has a configuration in which slits 4, 4 each having a shape symmetrical to each other in the upper and lower directions, that is, in the Y direction, are provided.
なお、5.6は上記インシュレータ1の内外周囲に各々
嵌合させた内筒と外筒を示す。Note that 5.6 indicates an inner cylinder and an outer cylinder fitted around the inside and outside of the insulator 1, respectively.
上記スリット2,3は、各々上記内筒5側を頂部とする
山形をなし、前者のスリット幅よりも後者のスリット幅
を大きく形威しである。The slits 2 and 3 each have a mountain shape with the top facing the inner cylinder 5 side, and the latter has a larger slit width than the former.
また上記スリット4,4は、各々U字形をなし、それら
のスリット幅は相等しい。Further, the slits 4, 4 are each U-shaped, and have the same width.
第3図は、上記インシュレータ1に対し上記内筒5側よ
りx、 x’、 yおよび2方向に荷重を負荷した場合
の荷重−撓み特性を各々示す。FIG. 3 shows load-deflection characteristics when loads are applied to the insulator 1 from the inner cylinder 5 side in x, x', y, and two directions.
同図から明らかなようにこのインシュレータ1は、上記

性をもつが、これは上記スリット2,3および4の面内
側が当接するまでは柔かいバネとして作用し、当接後は
硬いバネとして作用するからである。As is clear from the figure, this insulator 1 has nonlinear spring characteristics in the X, X', and Y directions, but this insulator 1 acts as a soft spring until the inner surfaces of the slits 2, 3, and 4 come into contact with each other. This is because it acts as a stiff spring after contact.
しかして上記スリット3の幅がスリット2の幅よりも大
きいことから、図示する如くX。However, since the width of the slit 3 is larger than the width of the slit 2, the width of the slit 3 is X as shown in the figure.
X′力方向ついての撓み特性が互いに相違する。The deflection characteristics in the X' force direction are different from each other.
なおこの実施例においては、Y方向よりもX。Note that in this embodiment, the X direction is higher than the Y direction.
X′力方向撓み易い傾向をもつ。It has a tendency to be easily deflected in the direction of the X′ force.
また2方向の荷重−撓み特性はリニアである。Moreover, the load-deflection characteristics in two directions are linear.
本実施例におけるインシュレータは、上記するようにX

イドリング振動に対する耐久性も高い。By arranging it so that it receives the X′ force direction, pitching in the Y direction, and yawing in the Z direction, it is possible to effectively reduce vibrations when the engine is idling, thereby reducing noise. Moreover, it has high durability against idling vibration.

上記トルク反力をきわめて良好に阻止しうる。Furthermore, in a front-wheel drive vehicle, a large torque reaction force is generated during sudden acceleration/deceleration, but the insulator of the present invention has different deflection characteristics in the X direction and that in the X' force direction. By arranging the engine to receive the rolling that occurs during acceleration in the X direction toward the wide slit side, and to receive the rolling that occurs during sudden deceleration in the X' force direction toward the narrow slit side,
The torque reaction force described above can be prevented very well.
