〔Example〕 1 to 4 show an embodiment of the present invention.

The radiator device of this embodiment includes a base plate 1 that is welded to the vehicle body and becomes a part of the body, and a radiator body 2 that has a support shaft 20 at the lateral end.
and an elastic holder 3 that elastically supports the radiator main body 2 on the base plate 1.

The elastic holder 3 is interposed between the base plate part 1 and the radiator main body 2, and is composed of a central metal fitting 4, an outer metal fitting 5, an elastic rubber part 6, and a retaining part 7.

The central metal fitting 4 is attached to the support shaft portion 2 of the radiator main body 2.
It has a long cylindrical shape with a central hole into which 0 is inserted. The central metal fitting 1 is made of aluminum die-casting.

The outer fitting 5 is made of metal, and includes a cylindrical body 52 having a larger diameter than the central fitting 4 and a cylindrical body 53 press-fitted into the cylindrical body 52.
It has a double cylindrical shape and has an inner circumferential surface 50 coaxially covering the outer circumferential surface of the central metal fitting 4. Outer metal fitting 5
is attached to the base plate part 1 by press fitting.

The elastic rubber portion 6 is interposed between the inner peripheral surface 50 of the outer metal fitting 5 and the outer peripheral surface 40 of the central metal fitting 4. The elastic rubber portion 6 is formed by injecting unvulcanized rubber into the space between the outer circumferential surface 40 of the central fitting 4 and the inner circumferential surface 50 of the outer fitting 5 and vulcanizing it. It is a rubber sleeve that substantially fills the space between the outer circumferential surface 40 and the inner circumferential surface 50 of the outer metal fitting 5. The elastic rubber portion 6 is attached to the outer circumferential surface 4 of the central fitting 4.
0, it is vulcanized and bonded to the inner circumferential surface 50 of the outer metal fitting 5. The elastic rubber portion 6 has holes 60 and 61 extending in the axial direction of the central fitting 4 and the outer fitting 5. hole 60,
61 is formed at a symmetrical position with the central metal fitting 4 interposed therebetween, as shown in FIG. Holes 60b, 61 on both sides
It has b. Therefore, as shown in FIG. 1, the elastic rubber portion 6 includes a lumpy rubber portion 64 that is vulcanized and adhered to the outer circumferential surface 40 of the central fitting 4 and the inner circumferential surface 50 of the outer fitting 5, bridging the two; It consists of a rubber portion 65 that is vulcanized and bonded to the inner circumferential surface 50 of the outer metal fitting 5 but not vulcanized and bonded to the outer circumferential surface 40 of the central metal fitting 4.

The retaining portion 7 is a rubber portion that is vulcanized and bonded to the inner circumferential surface 41 forming the central hole of the central metal fitting 4, and is in close contact with the outer circumferential surface of the support shaft portion 20 of the radiator body 2. As shown in FIG. 1, the retaining portion 7 is continuously formed in a cylindrical shape all around the inner peripheral surface 41 forming the central hole of the central metal fitting 4. As shown in FIG. The rubber hardness of the retaining portion 7 is approximately 45 to 55 degrees. Incidentally, the end portion of the retaining portion 7 has inclined guide portions 70 and 71.
is formed.

In this embodiment, as shown in FIGS. 3 and 4, the support shaft 20 of the radiator body 2 is inserted into the center hole of the central metal fitting 4, and the base plate 1 is attached to the body with bolts. A radiator main body 2 is attached to the body of a vehicle via a base plate part 1. At this time, as shown in FIG.
1 are arranged in the vertical direction of the radiator main body 2. Incidentally, FIG. 9 shows the spring characteristics of the radiator device according to this embodiment installed in this manner.

That is, in this installed state, when an external force is applied in the axial direction of the central fitting 4, that is, in the longitudinal direction of the radiator main body 2 (in the direction of arrow A) as shown in FIG. When the central metal fitting 4 is deformed in the axial direction (in the direction of arrow A), the elastic rubber part 6 related to the radiator device is configured to have holes 60 and 61, so when an external force is applied in the axial direction, the holes 60 and 61, the elastic rubber portion 6 is moved in the axial direction (arrow A
Therefore, the spring constant in the axial direction (direction of arrow A) can be made smaller.

Further, when an external force is applied in the radial direction of the central metal fitting 4, the elastic rubber portion 6 acts in the radial direction of the central metal fitting 4 (arrow B
direction, arrow C direction).

In other words, when an external force is applied in the vertical direction of the radiator body 2, that is, in the radial direction of arrow B (the height direction of the radiator body 2 as shown in FIG. 3), the elastic rubber portion 6 closes the holes 60, 61. Since the elastic rubber portion 6 is deformed while changing its shape, the elastic rubber portion 6 is easily deformed in the radial direction, and therefore the spring constant in the radial direction (direction of arrow B) can also be reduced. Furthermore, when an external force acts in the direction of arrow B, the rubber portion 64
After contacting the rubber portion 65, the spring characteristics change from before the contact, and therefore, as shown in FIG. 9, a bending point can be brought about in the deflection-load curve representing the spring characteristics. Further, when an external force is applied in the direction of arrow C, which is the radial direction perpendicular to the direction of arrow B, that is, in the width direction of the radiator body 2 as shown in FIG. As shown, since the center metal fitting 4 and the outer metal fitting 5 are bridged, the amount of deflection is correspondingly small and the spring constant in the direction of arrow C can be increased.

As described above, in this radiator device, the spring constants of the radiator main body 2 in the vertical direction (direction of arrow B), length direction (direction of arrow A), and width direction (direction of arrow C) can be changed.

Particularly in this embodiment, when the radiator body 2 is held on the base plate 1, the ring-shaped retaining portion 7 is in close contact with the entire circumference of the support shaft portion 20 of the radiator body 2, so that the radiator body 2 may be displaced. can be effectively suppressed.

A second embodiment of the radiator device according to the present invention is shown in FIGS. 5 and 6. The radiator device of this second embodiment is basically the same as the embodiment described above. However, the elastic holder 3 has an elastic rubber portion 6
and a rubber closure part 8 integrally formed with the retaining part 7. The closing portion 8 covers one opening in the axial direction of the central hole of the central fitting 4 .

In this way, the distal end of the support shaft portion 20 and the closing portion 8 come into contact with each other, and the closing portion 8 can prevent the support shaft portion 20 from coming off. It is effective in preventing it from coming off.

In addition, in the above-described embodiment, the elastic rubber portion 6 is
Although it consists of a rubber part 64 and a rubber part 65, it is not limited to this and does not need to have the rubber part 65.
