- the intermediate member 45 integrated with the elastic body is disposed at a position offset upward from the center line n in the height direction as a whole.
- the press-fitting height differs depending on the direction of the intermediate member when the press-fitting operation is performed in the press-fitting process according to the dimensions and positional relationships of the above elements.
- the intermediate member 45 is press-fitted until the open end 30a of the lid 30 comes into contact with the bottom 14 of the base 13 when the elastic body 20 is fitted in the normal direction.
- the press-fit amount is set so as not to reach the normal press-fit amount. The reason for this will be described with reference to FIG.
- the convex portion 62 Since the inner diameter d1 on the upper surface side of the intermediate member 45 is smaller than the outer diameter D1 of the oblique receiving portion 65 that becomes the engaging portion 68 (d1 ⁇ D), the convex portion 62 does not engage with the hole 46 of the intermediate member 45.

This is because the press-fitting allowance is reduced by approaching.
- the press-fitting jig 52 is a single member that can be engaged with both the front and back of the intermediate member 45. By making the jig side a single member that can be engaged only when the elastic body 20 is press-fitted in a normal posture, the amount of compression is changed in the height direction of the elastic body 20, and misassembly is easy.

- the convex portion corresponding to the convex portion 62 of this embodiment
- the step of press-fitting the elastic body 20 is performed at the upper end in the thickness direction of the elastic body 20 It is press-fitted by compressing between the lower end part.
- the elastic body 20 when the elastic body 20 is compressed, the elastic body 20 protrudes from the lid body 30, and a part of the elastic body 20 is sandwiched between the bottom wall portion 14 of the base 13 and the inner peripheral wall portion 35 of the lid body 30. There was a case.
- the upper jig 54 is pushed from above while supporting the intermediate portion in the thickness direction of the elastic body 20 from the bottom portion 14 toward the lid body 30.
- the upper part of the elastic body 20 is compressed and the elastic body 20 is press-fitted into the inner peripheral wall portion of the lid 30.
- the elastic body 20 was compressed toward the bottom wall portion 14 while supporting the middle portion in the thickness direction of the elastic body 20 (position of the center line n in the height direction shown in FIG. 5).
- the upper portion of the elastic body 20 is more strongly compressed than the intermediate portion in the thickness direction of the elastic body 20 (position of the center line n in the height direction of the elastic body shown in FIG. 5).
- the lower part of the elastic body 20 is also compressed from the middle part of the elastic body 20. Since the upper part of the elastic body 20 is strongly compressed and the lower part of the elastic body 20 is also compressed, it is difficult for the elastic body 20 to protrude from the lid 30. As a result, it is possible to press-fit the elastic body 20 between the base body 13 and the lid body 30 without impairing workability related to press-fitting.
- the suspension support 10 includes a base body 13 and a lid body 30 that is press-fitted into the base body 13. Since the lid 30 and the base body 13 are integrated by press-fitting, a fastening member or caulking for integrating the lid body 30 with the base body 13 is unnecessary. Since the fastening member is unnecessary, the suspension support 10 can be reduced in weight. In addition, since the coupling means for press-fitting the lid 30 to the base 13 is press-fitted, the maintainability of the elastic body 20 built in the suspension support 10 is ensured. As a result, according to the present invention, it is possible to achieve both weight reduction of the suspension support 10 and securing of maintainability.
- the lid 30 is coupled to the base 13 by press-fitting.
- press-fitting a joining process such as fastening or welding becomes unnecessary.
- both the base 13 and the lid 30 can be easily manufactured by press-molding a plate material, the suspension support 10 can be manufactured at a low cost.
- the suspension support 10 is fastened to the vehicle body side member 42 with bolts and nuts.
- Conventionally there has been a case of so-called co-tightening, in which a suspension support composed of a base and a lid and a suspension support are coupled to a vehicle body side member by bolts and nuts.
- maintainability of the elastic body disposed between the base body and the lid is ensured, but due to variations in the dimensions of the members on the vehicle body, variations in the press-fit state of the elastic bodies are likely to occur. As a result, the damper support characteristics are easily affected.
- the elastic body is held by press-fitting in the suspension support, and separately from this, the suspension support is coupled to the vehicle-side parts by bolts and nuts. There is no concern about variations in the press-fit state of the elastic body due to variations.
- the present invention is applied to an automobile.
- the present invention can also be applied to a three-wheeled automobile and can be applied to a general vehicle.
- the present invention is suitable for a suspension support provided in an automobile.
