For the lubrication oil supply to the supercharger, it is desirable that the structure that uses piping from the engine body be used because it can realize low cost, but a piping mounting structure is required for this, the appearance is poor and the cost is high. . Similarly, the intake duct and the piping for cooling water have a poor appearance, the number of parts for piping is large, and the cost is high. That is, the supercharger mounting base has only a function as a base, and each pipe such as lubricating oil is also provided with a dedicated part. Furthermore, when supplying the lubricating oil in the engine body to the supercharger, mist (exhaust gas and air mixed with the lubricating oil, especially in the middle of the lubricating oil passage for returning from the supercharger to the engine body, If the air-fuel mixture is not discharged to the outside of the lubricating oil passage, there is a risk that air outside the engine will enter the engine body and cause an explosion in the engine body.
