[Prior Art] The layout structure of the net benefit of air and heat is to install the engine on the side of the rear wheel of the Sukda-type vehicle and arrange it above the engine on the side (for example, refer to Japanese Patent Document 1). In addition, there is a position where the engine is disposed between the front wheels and the rear wheels of the Sukhtar vehicle. The position is above the engine and in front of the rear wheels (for example, refer to Japanese Patent Document 2). [Japanese Patent Document 1] Equity 1-25 119 (Page 2, Figure 3) [Japanese Patent Document 2] Japanese Patent No. 3-71317 (Page 3-4, Figure 1) Refer to the illustrations and explain the details above. The patent documents 1 and 2 are as follows. Fig. 13 is an explanatory diagram of a supporting body for a conventional locomotive (a copy of Fig. 3 of Patent Document 1). A conventional support body for a locomotive uses a two-stroke engine to dispose the engine / drive combination 13 on the left side of the rear drive wheels 17, and the upper part of the engine / drive combination 13 (within the outline) is provided with air (not shown) Cleaner 'houses the muffler 19 in a cavity -5- (2) 1233463 forming the front of the rear drive wheel 17. Fig. 14 is an explanatory diagram of a speed locomotive having a conventional 2-stroke engine (a copy of Fig. 1 of Patent Document 2). The conventional Scooter locomotive is provided with a carburetor 32 and an air purifier 34 above the engine 20 and in front of the rear wheels 24. At the same time, the air purifier 3 4 is connected to the carburetor 32 by a joint 33, forming a relatively Short suction tubes are long. [Summary of the Invention] [Problems to be Solved by the Invention] The locomotive support vehicle body of the above-mentioned FIG. 13 has a structure in which an air cleaner is provided on the upper part of the engine / drive combination 13 using a 2-stroke engine. To improve the suction efficiency, a predetermined amount must be ensured to ensure the volume of the suction pipe. Therefore, a predetermined length must be formed. For example, when the length of the 4-stroke suction pipe is set to a predetermined length, there is a possibility that the ventilation hood 11 will be interfered, and it is difficult to increase the degree of freedom in setting the length of the suction pipe. Although the speed locomotive of FIG. 14 described above uses the joint 33 for the connection of the carburetor 32 and the air purifier 34, the shape of the joint 33 is shaped and bent into a <-shape, so the suction of the joint 33 is large. resistance. In addition, since the suction pipe is connected to the front side of the air cleaner 34, the front side cannot be removed during maintenance of the air cleaner 34, which is extremely troublesome. Therefore, an object of the present invention is to provide a connection pipe of an air purifier and a carburetor that can be set to a predetermined bend and length, to obtain a reduction in the suction resistance of the suction device, and to improve the suction efficiency. Cover-6- (3) 1233463 At the same time, the configuration of the air purifier of the Scooter is easy to maintain. [Means for solving the problem] The first item in the scope of the patent application for achieving the above purpose is a power unit that integrates the engine with the transmission and the rear axle, and is arranged at the rear of the car body under the seat while being 'free swinging support' In a scooter-type vehicle with a frame, it is characterized in that a crankshaft of the engine is arranged on the side of the rear wheel, a carburetor is arranged above the engine, and air purifiers are arranged on the side of the carburetor and above the rear wheel. Device. While making the air outlet of the air purifier approximately equal to the height direction of the carburetor, it is close to the air outlet relative to the front-to-rear direction of the carburetor. It is not necessary to increase the bending of the connecting pipe of the air purifier to the carburetor. Increase the length of the suction pipe from the engine through the carburetor to the air purifier, expand the volume of the suction pipe, and improve the suction efficiency. The second item of the scope of patent application is characterized in that it has a front case and a rear case that are divided in the front-rear direction of the vehicle, the rear case is fixed on the engine side, and the carburetor is connected to the rear case through a connecting pipe. The air purifier has a side casing and a rear casing. The rear casing is connected to the carburetor by a connecting pipe. Therefore, the rear casing is fixed on the engine side, and the body cover can be opened to remove the front casing of the air cleaner. Body, easy maintenance of components. The third item of the scope of patent application is characterized in that the body cover under the seat and over the engine is rotated around the hinge provided at the rear side of the vehicle body as a center -7- (4) 1233463. By adopting the configuration of the air purifier of the present invention, the surroundings of the air purifier can be opened, and no labor is required for inspecting the air purifier. The fourth item of the scope of patent application is characterized in that the frame is a steel pipe frame: the frame is not an integral frame formed with the outer cover, so the outer cover can be removed for the maintenance of the air purifier.

The second fixing portion 56 is formed in the lower portion, and the third fixing portion 5 7 ′ is formed in the lower portion of the peripheral edge of the housing body 53. Therefore, the air cleaner 36 can be arranged at a predetermined position above the rear wheel 17. In addition, the shapes of the front and rear housings 46 and 47 of the air cleaner 36 shown in the embodiment of the present invention are one example. 'For example, the capacity of the air cleaner or the crankcase 6 can be changed according to the specifications of the engine. The fixed position or the position of the air inlet 51 can be changed. [Effects of the Invention] -16- (13) 1233463 The present invention can exhibit the following effects based on the above configuration. In item 1 of the scope of the patent application, the Scooter type vehicle, which combines the engine with the transmission and the rear wheel support, is swingably supported on the frame. The crankshaft of the engine is arranged on the side of the rear wheel. The carburetor is placed above the engine, and the air purifier is placed on the side of the carburetor and above the rear wheels. Therefore, the air outlet of the air purifier is roughly consistent with the height direction of the carburetor, and the air outlet is close to the front and rear direction of the carburetor. The connection pipe of the air purifier to the carburetor does not require large bending, and increasing the length of the suction pipe from the engine through the carburetor to the air purifier can increase the volume of the suction pipe and improve the suction efficiency. In addition, by forming the connecting pipe into an L-shaped bend, and setting the length of the connecting pipe to a predetermined length, the suction resistance can be suppressed within a predetermined range. In item 2 of the scope of the patent application, the air purifier has a front housing and a rear housing that divide the vehicle in the front-rear direction, fix the rear housing to the engine side, and connect the carburetor to the rear housing through a connecting pipe. Therefore, the rear case can be fixed on the engine side, the body cover can be opened, and the front case of the air purifier can be removed, so that the maintenance of components can be easily performed. In item 3 of the scope of patent application, the body cover under the seat and covering the engine is pivoted up and down with a hinge provided on the rear side of the vehicle body. Therefore, the configuration of the air purifier of the present invention can be used to open the air. Around the purifier, check the air purifier without man-hours. In addition, 'the body cover below the seat and covering the engine is pivoted up and down with a hinge provided on the rear side of the vehicle body, so the crankshaft of the engine is placed -17-1233463 (14) on the side of the rear wheel' Even if the carburetor is placed above the engine, it can still be turned on around the engine. In item 4 of the scope of the patent application, the frame is a steel pipe frame, and the frame is not an integral frame formed with the cover body. Therefore, the air purifier can be easily repaired by removing the cover body.
