An intermediate cylinder is fitted and arranged on an inner peripheral side of an outer member connected to the vehicle body panel side, an inner member is arranged inside the intermediate cylinder, and the inner member is connected to the strut rod side. Further, an elastically deformable elastic body is arranged so as to connect the intermediate cylinder and the inner member.

It is possible to position the intermediate cylinder in the axial direction and easily fix the intermediate cylinder. Further, since there is no upper bracket, the sealing material for sealing between the vehicle body panel and the outer member can be connected to the elastic body, and accordingly, the sealing material can be integrally formed with the elastic body.

Not only that, it became possible to form the sealing material integrally with the elastic body. As a result, as the number of parts is reduced, the cost of the parts is reduced and the assembly process for assembling the parts is simplified, and the strut mount is arranged between the vehicle body panel and the strut rod. Manufacturing costs are reduced.

で、請求項１の作用効果がより確実に達成される。The operation of the strut mount according to claim 2 will be described below. The strut mount according to this claim has the same operation as that of claim 1. However, in the present claim, a flange is formed on the intermediate cylinder so as to spread to the outer peripheral side, one side of this flange contacts the flange of the outer member, and the sealing material is arranged on the other side of this flange. It is configured to be done. That is, the intermediate cylinder is firmly fixed by contacting the intermediate cylinder with the flange portion of the outer member on one surface side of the flange portion formed on the intermediate cylinder, and the seal material is arranged on the other surface side of the flange portion. Thus, since the sealing material is stably supported by the intermediate cylinder, the function and effect of claim 1 can be achieved more reliably.

In the present invention, the inner peripheral side of the elastic body is vulcanized and bonded to the inner member, and the outer peripheral side of the elastic body is vulcanized and bonded to the intermediate cylinder. Therefore, as a result of eliminating the need to directly bond the elastic body to the outer member, the structure of the outer member, which tends to have a complicated shape when the elastic body is vulcanized and bonded, can be simplified, which also contributes to the strut mount. It is possible to reduce the manufacturing cost.

The upper surface of the outer member 12 is brought into contact with the lower surface of the panel 36, and the vehicle body panel 36 and the outer member 12 are joined by welding, screwing, or the like. However, at this time, the gap between the vehicle body panel 36 and the outer member 12 is surely closed by the sealing material 26. That is, as a result, the strut mount 10 shown in FIG. 1 is arranged so as to be arranged between the strut rod 32 and the vehicle body panel 36.
Will be installed in the vehicle.

うに配設されている。Next, the operation of the strut mount 10 of this embodiment will be described. The intermediate cylinder 20 is fitted and arranged on the inner peripheral side of the cylindrical outer member 12 connected to the vehicle body panel 36 side, and the inner member 22 is positioned inside the intermediate cylinder 20. 22 is connected to the strut rod 32 side. Further, an elastic body 24, the inner peripheral side of which is vulcanized and adhered to the inner member 22 and the outer peripheral side of which is vulcanized and adhered to the intermediate cylinder 20, is provided between the outer member 12 and the inner member 22 via the intermediate cylinder 20. It is arranged so as to be elastically deformable.

ネル３６側に振動が伝達され難くなる。Therefore, when the vibration from the road surface is transmitted to the inner member 22 via the strut rod 32, the elastic body 2
As 4 is deformed, the vibration is absorbed by the resistance based on the internal friction of the elastic body 24, and the vibration is reduced.
Vibration is less likely to be transmitted to the vehicle body panel 36 side connected to the intermediate cylinder 20 via the outer member 12.

る。Further, in this strut mount 10,
A flange portion 12A is formed on the upper end side, which is one end side of the outer member 12, so as to spread to the outer peripheral side.
By contacting the collar portion 20A of the intermediate cylinder 20 with A, the intermediate cylinder 20 can be axially positioned without the upper bracket, and the intermediate cylinder 20 can be easily fixed. Furthermore, since there is no upper bracket, the body panel 36
The sealing material 26 for sealing between the outer member 12 and the outer member 12 can be connected to the elastic body 24, and accordingly, the sealing material 26 can be integrally formed with the elastic body 24 with a rubber material.

工程が単純化されるようにもなった。As described above, in the present embodiment, the upper bracket is shared with the vehicle body panel without forming the outer member by the upper bracket and the lower bracket as in the conventional strut mount, so that the upper bracket is unnecessary. Not only is it possible to form the sealing material 26 integrally with the elastic body 24. Along with this, the elastic body 2
Since the 4 and the sealing material 26 are made of a rubber material so as to be integrated with each other, they can be integrally vulcanized and the vulcanization process is simplified.

ウント１０の製造コストが低減される。As a result, as the number of parts is reduced, the cost of parts is reduced and the assembly process for assembling the parts is simplified, and the parts are arranged between the vehicle body panel 36 and the strut rods 32. The manufacturing cost of the strut mount 10 is reduced.

The seal member 26 is arranged on the upper surface side, which is the other surface side of the flange portion 20A, in contact with the flange portion 12A. Therefore, the intermediate cylinder 20 is brought into contact with the flange portion 12A of the outer member 12 on the lower surface side of the flange portion 20A formed on the intermediate cylinder 20 so that the intermediate cylinder 20 is securely fixed, and also on the upper surface side of the flange portion 20A. By disposing the sealing material 26, the sealing material 26 is stably supported by the intermediate cylinder 20.

A tubular portion is present at each position of 0, and this tubular portion allows the intermediate tube 2 to be provided on the inner peripheral side of the outer member 12.
0 is more reliably fitted, and the sealing material 26 is more stably supported by the intermediate cylinder 20.

る。On the other hand, in the present embodiment, not only the elastic body 24 and the sealing material 26 are integrally formed of a rubber material, but also the inner peripheral side of the elastic body 24 is vulcanized and adhered to the inner member 22. The outer peripheral side of the elastic body 24 is vulcanized and bonded to the intermediate cylinder 20. Therefore, as a result of eliminating the need to directly bond the elastic body 24 to the outer member 12, it is possible to simplify the structure of the outer member 12 that tends to have a complicated shape when the elastic body 24 is vulcanized and bonded. Also, the manufacturing cost of the strut mount 10 can be reduced.
