In order to soften the spring in the S direction, which is the input direction of the roll vibration, the gaps 4 and 5 are formed in the rubber 3 mounted between the inner cylinder 1 and the outer cylinder 2 as shown in FIG. The radial cross section of No. 3 is formed in a V shape. Further, the inner cylinder 1 is not provided at the concentric position with the outer cylinder 2, but is provided eccentrically so as to be concentric with the outer cylinder 2 when 1 G is applied to the inner cylinder 1.

ムの形状を変えるだけでは限界があった。In the engine mount in which the rubber 3 is formed in a V-shape, the spring ratio in the P direction and the S direction becomes large, which is effective in terms of durability and anti-vibration performance.
In order to further improve durability and anti-vibration performance, it is desirable that the spring ratio in the P direction and the S direction be larger, but there was a limit only by changing the shape of the rubber.

フを入れたものである。In order to achieve the above object, the present invention is directed to an input direction of roll vibration of an engine substantially in the middle of an inner cylinder and an outer cylinder of rubber and to an input direction perpendicular to an engine load. The interleaf is inserted so as to be inclined in substantially the same direction as.

Therefore, the spring ratio in the P direction and the S direction can be increased. Although no interleaf is inserted, the spring ratio in the P and S directions is 1:
While it is 0.7, it is 1: 0.5 in the present invention.

る。In the first embodiment shown in FIG. 1, the angle α formed by the input direction of the engine roll vibration, that is, the S direction, with respect to the vertical input direction of the engine load, that is, the P direction.
20 to 50 ° (30 to 40 in the illustrated embodiment)
), And voids 4 and 5 are formed in the rubber 3 mounted between the inner cylinder 1 and the outer cylinder 2. The rubber 3 has a V-shaped cross section in the radial direction. Inner tube 1 and outer tube 2 of rubber 3
Input direction of the roll vibration of the engine (S direction) approximately in the middle of
The interleaf 6 is inserted so as to incline in substantially the same direction. The angle β formed by the interleaf 6 and the vertical line in the P direction is preferably larger than 20 ° and smaller than 90 °, more preferably larger than 50 ° and smaller than 90 °. The relationship between the angle α and the angle β is
It is preferable that α <β <90 °. Angle α and angle β
Is the same or the angle α is large, the effect of hardening the spring in the P direction is small, in other words, it is not useful for improving durability. When the angle β is 90 ° or larger than 90 °, the effect of softening the spring in the S direction is small,
That is, the anti-vibration performance is inferior. As the interleaf 6 put in the rubber 3, a steel plate or a synthetic resin plate is preferably used.

となる。As described above, according to the present invention, the input direction of the roll vibration of the engine is substantially in the middle of the inner cylinder and the outer cylinder of the rubber and is substantially the same as the input direction of the roll vibration of the engine with respect to the vertical input direction of the engine load. Since the interleaf is inserted so as to incline, the ratio of the spring in the input direction of the engine load perpendicular to the spring in the input direction of the roll vibration of the engine can be made larger, resulting in durability and anti-vibration performance. Can be improved. Further, if the interleaf is set in the mold when vulcanizing and molding the rubber without changing the shape of the rubber, it can be easily manufactured and the manufacturing becomes easy.
