According to the present invention, in order to achieve the above object, a first mounting plate includes a first embedded portion embedded in an elastic body, and an elastic body connected to the first embedded portion. And a first abutting portion protruding outward from the first flange portion so as to abut the tip against the support, and a second mounting plate is provided with the first embedded portion. A second buried portion buried in the elastic body on the side opposite to the supported body with respect to the portion, a second flange portion extending to the outside of the elastic body connected to the second buried portion, and a front end of the second buried portion. A second contact portion protruding from the second flange portion to the supported body side so as to make contact with the second flange portion. The amount of protrusion of the first and second contact portions from the first and second flange portions is determined by a natural elastic body. In the state, it is set so that the tips of the first and second abutting portions are located inside the first and second joining surfaces.

The second mounting plate 24 is provided with the first embedded portion 23a.
Intercooler I and the second buried portion 24a _C A which is embedded in the elastic body 25 on the opposite side, the second buried portion continuous with 24a overhangs outwards of the elastic body 25 three second flange portion 2 with respect to
4b _1, 24b _2, 24b ₃ and, each of the second flange portion 24b so as to abut the tip intercooler I _{C 1,} 24b _2,
Consists of 24b ₃ and four second contact portion 24c which projects, the second buried portion 24a is formed substantially in a shape corresponding to the first buried portion 23a, the second contact portion 24c is a cylindrical body first 2 flange portion 24b _1, 24b _2, are formed by welding bind to 24b _3.

The first flange 23b ₁ and the second flange 2
4b ₁ projects from the first and second buried portions 23a and 24a to opposite sides, and a pair of first and second contact portions 23a.
c, 24c are first flange portion 23b ₁ and the second flange portion 24b ₁
Are connected to each other. Also, the first flange portions 23b ₂ , 23b
_3, the first flange portion 23 in spaced side from the first flange portion 23b ₁
in the direction orthogonal to the projecting direction of b ₁ is flared from the first buried portion 23a, the second flange portion 24b _2, 24b ₃ and the second overhang of the flange portion 24b ₁ on the side remote from the second flange portion 24b ₁ It extends from the second embedded portion 24a in a direction perpendicular to the direction. Moreover, the first contact portions 23c are provided on the first flange portions 23b ₂ and 23b _3.
Are connected one by one, and the second contact portions 24c are connected one by one to the second flange portions 24b ₂ and 24b ₃ .

[0015] With such a configuration, four first contact portion 23c is made to be allocated to each of four apex angle position of the virtual trapezoid T _1, four second contact portion 24c
It will be placed into four apex angle position of the virtual trapezoid T ₂ that is offset from each other above a virtual trapezoid T ₁ be reversed arrangement.

The first contact portions 23c allow the bolts 29 to be screwed to the supercharger S _C to pass therethrough, respectively.
The second contact portion 24c allows the bolt 30 to be screwed to the lower tank 16 to pass therethrough, and the first and second contact portions 23c and 24c are arranged as described above, so that the mounting member 22 is mounted. , The turbocharger S _C and the lower tank 16 with substantially uniform tightening force along the circumferential direction.
Can be tightened.

By the way, as shown in FIG.
In a natural state where no external force is applied to the first contact portion 23
c and the tip of the second contact portion 24c are elastic members 2
5, the first and second joint surfaces 27, 2
The first flanges 23b ₁ , 23b ₂ , 23b of the first abutment 23c are positioned inward by distances L ₁ , L _{2 from} FIG.
Projecting amount from _3, and the projecting amount from the second flange portion 24b _1, 24b _2, 24b ₃ of the second contact portion 24c is set.

[0018] Next, to explain the action of this embodiment, in supporting the intercooler I _C in the supercharger S _C through the mount member 22, a bolt 29 inserted through the first contact portion 23c supercharged screwed into vessel S _C tightened to the tip of the first contact portion 23c comes into contact with the supercharger S _C, the second contact portion 2
When the bolt 30 inserted through 4c is screwed into the lower tank 16 and tightened until the second contact portion 24c contacts the lower tank 16, a compressive stress acts on the entire elastic member 25 in the tightening direction. Therefore, the first of the elastic body 25
And the second joint surfaces 27 and 28 are surfaces extending in the vertical direction, and even if a shearing force acts between the first embedded portion 23a and the second embedded portion 24a and the elastic body 25, the compressive stress acts in advance. As a result, the shearing force is reduced, and the first and second buried portions 23a, 24a are peeled off from the elastic body 25, or the elastic body 25 itself is cracked. This can be avoided as much as possible, and the durability of the mount member 22 can be improved.

[0019] FIG. 5 shows another embodiment of the present invention, the first person by bending a part of 'the first flange portion 23b in the' first mounting plate 23 to the supercharger S _C side 'to form a second mounting plate 24' abutting portion 23c to form a 'second contact portion 24c is bent a part of the Roatanku 16 side of the intercooler I _C' second flange portion 24b of the mount member 22 '
In such a case, the member such as the cylindrical body of the above embodiment is not required, which can contribute to a reduction in the number of parts.

The members denoted by reference numerals 23 and 23 'are used as second mounting plates on the supported body, and the members denoted by reference numerals 24 and 2'
The members with 4 'may be attached to the support as first attachment plates.

[0021]

As described above, according to the present invention, the first mounting plate has the first buried portion buried in the elastic body and the first bulging portion extending from the first buried portion to the outside of the elastic body. A flange portion, and a first contact portion protruding from the first flange portion toward the support member so that the tip abuts on the support member, wherein the second mounting plate is opposite to the supported member with respect to the first embedded portion. A second buried portion buried in the elastic body on the side, a second flange portion extending from the second buried portion to the outside of the elastic body, and a second flange portion for contacting the tip with the supported member. A second contact portion protruding toward the supported body, and the amount of protrusion of the first and second contact portions from the first and second flanges is set to a first and a second when the elastic body is in a natural state. Since it is set so that the tips of the first and second contact portions are located inside the second joint surface, it is possible to apply a compressive stress to the entire elastic body. Can thereby play a relaxation of the applied prevention and shear forces of tensile stress causing accelerated deterioration of the elastic body, it is possible to improve the durability.
