Description

Saddle-ride type vehicle Technical Field The present invention relates to a saddle-ride type vehicle. The present application claims priority based on japanese patent application No. 2024-194018 filed on 5 at 11/2024, the contents of which are incorporated herein by reference. Background Conventionally, turbochargers that use the energy of exhaust gas from an engine and turbochargers that use a part of the driving force of the engine are known as superchargers used in engines (internal combustion engines) for vehicles. In recent years, an electric supercharger using an electric motor for driving the supercharger has been known (for example, refer to japanese patent application laid-open No. 2009-228624). Disclosure of Invention However, in a saddle-ride type vehicle such as a two-wheeled vehicle, the components tend to be exposed to the outside more easily than in a four-wheeled vehicle. Therefore, there is a problem that the components of the two-wheeled vehicle are easily damaged as compared with the four-wheeled vehicle. The present invention provides a saddle-ride type vehicle in which a supercharger used in an internal combustion engine is hardly damaged from the outside. In order to achieve the above object, a saddle-ride type vehicle according to an aspect of the present invention employs the following configuration. (1) The present invention provides a saddle-ride type vehicle 1 including an internal combustion engine E and a supercharger 50 for compressing air and supplying the compressed air to the internal combustion engine E, wherein the saddle-ride type vehicle includes a head portion 6 for supporting a front wheel suspension member 3A at a front portion of a vehicle body 5B, and a pair of left and right frame portions 7 branched from the head portion 6 to the left and right and extending rearward, and the supercharger 50 is disposed in a region R3 surrounded by the head portion 6 and the left and right frame portions 7. According to the aspect of (1) above, the supercharger is arranged in the region surrounded by the head and the left and right frame portions, whereby the supercharger is hardly exposed to the outside and is hardly damaged from the outside. In addition, the arrangement space of the supercharger having the rotating body and the like is easily secured, the supercharger is arranged near the left and right center of the vehicle body to make the weight balance good, and even if the internal combustion engine has a plurality of cylinders arranged in the vehicle width direction, the intake air to each cylinder can be easily equalized. (2) In the aspect of (1) above, the saddle-ride type vehicle may include throttle devices 35 and 36, downstream ends of which are connected to cylinders 33 and 34 of the internal combustion engine E, and a surge tank 60, connected to upstream ends of the throttle devices 35 and 36, and the boost intake air may be introduced from the supercharger 50 to the surge tank 60, wherein the surge tank 60 is disposed behind the supercharger 50. According to the aspect of the above (2), by disposing the surge tank behind the supercharger, the supercharger and the surge tank are connected in a straight line through the connecting pipe extending in the front-rear direction, and the supercharged intake air can be efficiently introduced from the supercharger to the surge tank. By connecting the supercharger and the surge tank linearly in the front-rear direction, the connection pipe can be shortened, the weight and cost can be reduced, and the loss of the supercharging pressure can be easily suppressed. (3) In the aspect (2), the surge tank 60 may be disposed between the left and right frame portions 7 in a plan view. According to the aspect of the above (3), the surge tank is disposed between the left and right frame portions, whereby the supercharger and the surge tank can be arranged compactly in a concentrated manner. (4) In the aspect (1) above, the supercharger 50 may be provided with a suction port 52a that opens outward in the vehicle width direction, and the suction port 52a may be disposed in a region R2 surrounded by the plurality of frame members 15, 17 in the frame portion 7 in a side view. According to the aspect of (4) above, the suction port of the supercharger is arranged in the region surrounded by the frame member of the frame portion in side view, whereby the suction passage can be easily connected to the suction port from the vehicle width direction outside. The supercharger itself is disposed between the left and right frame portions, whereby the weight balance including the supercharger is improved, and even if the internal combustion engine has a plurality of cylinders aligned in the vehicle width direction, the intake air to each cylinder can be easily equalized. (5) In the aspect (2) above, the supercharger 50 may be configured to suck air from a suction port 52a that opens in the axial direction of the rotating body and to discharge the sucke
