However, when the mechanical supercharger is mounted on the engine body side as described above by using the supercharger mounting bracket having the above structure, the mechanical supercharger is In addition to the driving sound of itself, the vibration and driving sound generated by the driving of the mechanical turbocharger are transmitted to the turbocharger mounting bracket having the plate-shaped side wall part of a large area and resonate, and the side wall part and the engine. There is a problem that vibration and noise are further increased because the remaining space between the main body and the main body becomes a resonance space with engine vibration. Further, in some cases, it is possible that the side wall portion collides with the wall surface on the engine body side in the V bank space portion due to the amplified vibration. It is also assumed that the ebbing will occur even when the supercharger is assembled, and in such a case, for example, in the case where the engine body side cylinder head part is formed by sand casting, a part of the background is missing. However, it is considered possible that the missing member may enter the joint surface between the bottom portion of the supercharger mounting bracket and the engine body to deteriorate the joint state. Then, if an oil passage is formed at the joint, there is a problem that the sealing property is also impaired.

That is, in the structure, first, the side wall portion of the supercharger mounting bracket and the engine main body side of each of the left and right banks, for example, the cylinder head wall surface, are transmitted by the vibration from the mechanical supercharger. Since an elastic member having a high vibration damping function is interposed between the elastic members, the vibration generated in the mechanical supercharger during driving is transmitted to the elastic member via the side wall portion of the turbocharger mounting bracket, and the elastic member Is effectively absorbed, and the presence of the elastic member eliminates the conventional resonance space, so that the noise due to the resonance with the engine-side vibration noise as described above is less likely to occur.

Next, since the elastic member is fixedly provided on the engine body side, unlike the case where the elastic member is attached to the side wall portion side of the supercharger mounting bracket, the meat thereof is different. It is possible to assemble as usual without reducing the thickness and overhanging width at all, it does not reduce workability during assembly, and it is easy to assemble without paying attention to the collision with the engine side. The above-described vibration damping action can be realized. Therefore, there is no restriction on the effective space for installing the supercharger and workability. Workability during assembly is rather improved.

For example, when the engine body side cylinder head is sand cast, a part of the ground surface of the wall surface of the cylinder head is liable to be chipped due to a collision with the side wall portion of the turbocharger mounting bracket during assembly. . When the missing member enters the joint surface between the bottom of the turbocharger mounting bracket and the engine body side, the joint state and the fixed state deteriorate. However, in the present invention, since the presence of the elastic member having the configuration of the invention described in claim 1 makes it possible to avoid direct dewatering between the supercharger mounting bracket and the engine body side cylinder head wall surface, such a background It is possible to prevent a part of the engine from being lost, and the state of joining and fixing the bottom of the turbocharger mounting bracket to the engine body is good.

Therefore, according to the present invention, first, as in the third aspect of the present invention, the cylinder head of the engine body is sand-cast and a part of the ground surface of the wall surface is dried with the supercharger mounting bracket during assembly. Even in the state of being easily chipped due to a collision or the like, since the existence of the elastic member according to the structure of claim 1 which is the premise thereof prevents the direct collision, a part of such background is missing. You don't have to invite. Therefore, similarly, it becomes easy to ensure the reliability of the sealing property of the joint portion of the bottom portion of the turbocharger mounting bracket where the oil passage is formed and the engine body.
