The side (inside of the vehicle body) is inclined downward so that the ruler and 155' are directed to the right air introduction port 154. It is as described above that the water and the water are not easily entered from the upper side, because the fixed side pulley belonging to the outer stepless speed changer 35 is attached to the heel guide portion of the air introduction duct of the transmission case cover by the rotation of the belt type U8. The external air introduction port 96151362 200842236 154 of the cooling fan 51 member 15G attached to the heel guide 7 introduces outside air into the casing air inlet 6c via the external air passage 16 亚 as a cooling air. The belt-type stepless speed changer 35* body exhaust duct 36d is discharged to the outside in the belt type stepless speed change chamber. 'So' even if foreign matter such as mud or water intrudes from the outside air inlet port 1 into the outside air passage (10), the invading foreign matter will pass through the discharge passage 17 composed of the ridges 157, 167 and the ridges 156, 166. 〇, and discharged to the outside, thus preventing foreign matter from intruding into the belt type shifter chamber zero 70. The upper wall portions 152u, 162u of the heel guide member 150 extending upward from the transmission case cover 36 belong to the actual guide portion 15()u, as shown in Fig. j, the guide portion 150u is compliant with the side view Then, the rear end portion of the rear seat portion 15r of the footrest 15 is formed such that a part thereof overlaps from the outside and extends upward so as to block the upper concave portion 19. Stepping on the heel Fh of the common rider's foot F (shown in the figure of the second Lulu point chain) on the rear seat pedal portion l5r, the recess 19 is blocked from the inside of the vehicle body and is guided by the guide portion 150u. guide.

The filter air suction port 25i that opens toward the front end of the suction duct 25b is located at a position inside the guide portion 15〇u that is retracted from the heel guide member 15 (see FIGS. 3 and 4). Viewed from the side, it overlaps the guide 15 〇u state (see Fig. 2). 96151362 22 200842236 According to this, since the guide bow portion 15〇u of the heel guide member 150 conceals the filter air suction port 25i of the air cleaner 25 from the outer side, the mud and water can be prevented. Other foreign matter intrudes into the air cleaner 25. The cylinder block 32 covering the internal combustion engine 30 and the above-described cover 68 around the cylinder head 33 are embedded from the rectangular opening of the front end portion as shown in FIGS. 2 to 5: the cylinder head cover 34 protrudes forward, and the rectangular opening is opened from the rectangular opening The upper side wall 68u, the lower side wall 68d, and the left side wall 681 extend rearward along the side of the cylinder head 33 and the cylinder block ^, and the right side wall is gradually separated from the cylinder head 33 and the cylinder bore 32. Bulging, i is coupled to the fan cover 67. In addition, since the fan cover 67 is a front half of the circumference of the annular frame 67a with the crank shaft 4〇 as a central axis, the rear end edge of the right side wall 68r of the outer cover 联 is screwed by a screw 12 ,, and the ring frame 67 & The portion other than the front half of the circumference is screwed to the right end edge of the right unit casing 3ir by bolts 121, so that the fan cover 67 corresponds to the elongated structure of the outer cover 68, and is set and forced on the right side wall.

Therefore, the high-temperature duct cooling air discharged from the air outlet below the heel guide member 15 is mainly moved toward the rear along the lower side of the transmission box cover 36. The side of the transmission case cover 36 rises, and the possibility of being sucked into the air cleaner π 25i and the external air introduction port 154 is still low, thereby preventing the intake air temperature from rising and the belt type stepless speed change machine. The cooling effect is reduced. Further, in the vehicle body width direction, the outside air introduction port 154 is disposed between the filter π as the air intake port 25i and the exhaust port 69e of the exhaust duct 69 (see Fig. 4). Therefore, when the vehicle is stopped or the like, even if the cooling air discharged from the air outlet 69e rises, it will be first guided to the relatively close external air introduction port 154, thereby further reducing the air intake of the filter reaching the farther place. Mouth and 96151362 25 200842236 The possibility of inhalation prevents the inspiratory temperature from rising.

Water and other foreign matter invade the filter air intake. According to the above, since the heel guide member 150 is configured to have both the outer air guiding and the lower side, the recess 19 of the left rear end edge of the body cover 丨5, 丨7 is guided. The portion 15〇11 guides the rider from stepping on the heel of the leg portion F of the rear seat pedal portion 15r from the inside, and can perform external air introduction by the f-belt type stepless speed changer 35 to reduce the number of parts. The number and number of assembly steps can reduce costs. The guide portion 150u extending upward from the mounting portion of the transmission case cover 36 of the heel guide member 15 is provided with external air introduction: 154, and the external air introduction port 154 faces the guide portion 150u. The center side of the body width is open, so that the inhalation of mud and water can be prevented more effectively. Further, the guide portion 150U in the external air introduction port 154 is located at the recess 19 below the vehicle body cover 17 from the side view (see FIG. 1), and is exposed to the outside, so that the lower temperature which is not heated can be taken in.
