They are connected via a mounting member 22 according to the following. Further, an inlet 20 and an outlet 21 of cooling water are opened at the upper and lower parts of the heat exchange section 14, respectively.

In FIGS. 2 and 3, the mount member 22 includes a part of the first metal mounting plate 23 that is coupled to the supercharger S _C and a part of the first metal mounting plate 23 that is coupled to the lower tank 16 of the intercooler I _C. 2. A part of the mounting plate 24 is made of rubber or the like and is formed into a rectangular cylindrical shape and has a substantially rectangular flow hole 26 corresponding to the discharge port 13 of the supercharger _SC and the inlet 19 of the lower tank 16. The elastic body 25 has a first joint surface 27 connected to the supercharger _SC and a second joint surface 27 connected to the lower tank 16 on both sides of the elastic body 25. A joint surface 28 is provided.

The first mounting plate 23 includes a first buried portion 23a buried within the elastic body 25, and three first collar portions 23b 1 that are connected to the first buried portion 23a and protrude outward from the elastic body 25 _. , 23 b ₂ , 23 b ₃ and four first abutments protruding from the respective first flanges 23 b ₁ , 2 3 b ₂ , 23 b ₃ toward the supercharger S _C so that their tips abut against the supercharger S _C. The first buried portion 23a is formed in a shape that substantially corresponds to the cross-sectional shape of the elastic body 25, and each first abutment portion 23c connects the cylindrical body to the first collar portions 23b ₁ and 23b ₂ . , 23b ₃ by welding.

[0013]The second mounting plate 24 includes a second buried portion 24a buried in the elastic body 25 on the opposite side of the intercooler I _C with respect to the first buried portion 23a, and an elastic body connected to the second buried portion 24a. Three second flanges 24b ₁ , 24b ₂ , 24b 3 project outward from the body 25 and protrude from each of the second flanges 24b ₁ , 24b ₂ , 24b ₃ so as to bring the tips into contact with the intercooler _{IC .} The second buried part 24a is formed in a shape that almost corresponds to the first buried part 23a. ₁ , 24b ₂ , and 24b ₃ by welding.

[0014]The first flange 23b ₁ and the second flange 24b ₁ extend from the first and second buried portions 23a, 24a to opposite sides, and form a pair of first and second abutting parts. The portions 23c and 24c are connected to the first flange 23b ₁ and the second flange 24b ₁ , respectively. Further, the first flange portions 23b ₂ and 23b ₃ are extended from the first buried portion 23a in a direction perpendicular to the direction in which the first flange portion 23b ₁ is extended on the side away from the first flange portion 23b ₁ , and the second flange portions 23b 2 and 23b 3 are The flange portions 24b ₂ and 24b ₃ extend from the second buried portion 24a in a direction perpendicular to the direction in which the second flange portion 24b ₁ extends on a side separated from the second flange portion 24b ₁ . Moreover, one first contact portion 23c is connected to each of the first collar portions 23b _{2 and} 23b ₃ , and one second contact portion 24c is connected to each of the second collar portions 24b2 and _24b3 . be done.

[0015] With this configuration, the four first contact parts 23c are arranged at the four apex positions of the virtual trapezoid _T1 , and the four second contact parts 24c are arranged at the four apex positions of the virtual trapezoid T1. The virtual trapezoid T ₁ is arranged oppositely to the virtual trapezoid T 1 and is arranged at four apex positions of the virtual trapezoid T ₂ which are shifted from each other.

The first contact portions 23c are for inserting bolts 29 to be screwed into the supercharger _SC , and the second contact portions 24c are for inserting bolts 30 to be screwed into the lower tank 16. By arranging the first and second abutting portions 23c and 24c as described above, the mount member 22 can be tightened with approximately equal tightening force along the circumferential direction of the supercharger _SC . And it becomes possible to fasten it to the lower tank 16.

By the way, in a natural state where no external force is applied to the elastic member 25 as shown in FIG. The amount of protrusion of the first contact portion 23c from the first flange portions 23b ₁ , 23b ₂ , 23 b ₃ such that the first contact portion 23c is located inwardly by a distance L ₁ , L ₂ than the first and second joint surfaces 27 and 28 . , and the amount of protrusion of the second contact portion 24c from the second collar portions 24b ₁ , 24b ₂ , 24b ₃ are set.

Next, to explain the operation of this embodiment, when supporting the intercooler I _C to the supercharger S _C via the mount member 22, the bolt 29 inserted into the first contact portion 23c is connected to the supercharger The bolt 30 inserted through the second contact part 24c is screwed into _the lower tank 16 and tightened until the tip of the first contact part 23c contacts the supercharger _SC . When the contact portion 24c is tightened until it comes into contact with the lower tank 16, compressive stress is applied to the entire elastic member 25 along the tightening direction. Therefore, the first and second joint surfaces 27 and 28 of the elastic body 25 are surfaces extending in the vertical direction, and a shearing force acts between the first buried portion 23a and the second buried portion 24a and the elastic body 25. However, since the compressive stress acts in advance, the shearing force is relaxed, and peeling occurs between the first and second buried portions 23a, 24a and the elastic body 25, or the elastic body Cracks in the body 25 itself can be avoided as much as possible, and the durability of the mount member 22 can be improved.

FIG. 5 shows another embodiment of the present invention, in which a part of the first flange 23b' of the first mounting plate 23' is bent toward the supercharger S _C to attach the first part. A part of the second flange 24b' of the second mounting plate 24' is bent toward the lower tank 16 side of the intercooler _IC to form a second abutting part 24c', and the mounting member 22' may be constructed, and in this way, members such as the cylindrical body of the above-mentioned embodiments are not required, contributing to a reduction in the number of parts.

[0020] In addition, the members with reference numerals 23 and 23' can be attached to the supported body as a second mounting plate. The members designated with reference numerals 24 and 24' are respectively attached to the support as the first mounting plate. It is also good to do so.

[0021]

[Effect of the idea]

As described above, according to the present invention, the first mounting plate is attached to the first mounting plate embedded in the elastic body. a first flange extending outward from the elastic body and connected to the first buried part; a first contact portion protruding from the first flange toward the support body, and a second contact portion protruding from the first flange toward the support body; The mounting plate is buried in the elastic body on the opposite side of the supported body with respect to the first buried part. a second buried part, a second collar part that extends outward from the elastic body and is connected to the second buried part, and a tip a second contact portion that protrudes from the second flange toward the supported object in order to bring it into contact with the supported object; The amount of protrusion of the first and second contact portions from the first and second collar portions is determined by the elastic body. The first and second abutting surfaces are inwardly from the first and second joint surfaces when in a natural state. Since it is set to position the tip of the elastic body, compressive stress is applied to the entire elastic body. This prevents the application of tensile stress that accelerates the deterioration of elastic bodies. This can alleviate shearing forces and improve durability.
