In the bottom wall of the pedal portion 22, the lower second guide wall 21E extends to the first! Since the guide wall 21C is behind, the mixing of the air sent through the pedal portion 22 and the air below the pedal portion 22 can be further suppressed. The step 21D is formed to extend rearward, and the difference is larger. Therefore, the air inside the pedal portion 22 can be guided upward by the step 21D, and the air below the pedal portion 22 can be made along the surface of the first guide wall 21C located above. Guided to the rear of the pedal portion 22. A concave surface 49 that extends in the longitudinal direction and is recessed toward the inner side is formed on the side surface of the pedal portion 22. With the concave surface 49, it is easy to form another wind guiding path, and the mixing with the air of the other wind guiding paths is suppressed. The concave surface 49 is formed on the lower surface of the step portion 22, and is formed adjacent to the surface of the upper side wall 21A. The step is provided by the convex portion 50 provided between the upper surface and the concave surface 49, thereby further suppressing the mixing of the air of the other air guiding passages. The prime mover 29 includes an engine 25 and an exhaust pipe 39 extending rearward from the engine 25. The exhaust pipe 39 is connected after the bottom wall of the pedal portion 22 is communicated to the upper first guide wall 21C. The exhaust pipe, which has less influence on the cooling water and the mud, is introduced as the air below the plate P22, so that most of the air sent through the pedal portion 22 can be guided to other parts. The exhaust pipe 3 9 is sufficiently cooled on one side. The prime mover 29 includes an engine 25 that forms an oil reservoir 54 at a lower portion. Engine 25

O:\91\91758.DOC -17-1274009 At least a part of the oil reservoir 54 is disposed behind the second guide wall 21E located below the pedal portion 22. With this configuration, the air is guided to the oil reservoir 54 where the temperature is easily raised. The prime mover 29 includes an engine 25, and the intake port 25A of the engine 25 is disposed behind the pedal portion 22 and above the pedal portion. With this configuration, the cleaner air guided to the upper side through the inside of the pedal portion 22 is supplied to the engine 25. Further, the prime mover 29 includes a power transmission mechanism 27, and is provided inside the air-cooling power transmission mechanism 27, and the intake port 27A for taking in air is disposed above the upper surface of the pedal portion 22 behind the pedal portion 22. With this configuration, the cleaner air guided to the upper side through the inside of the pedal portion 22 is supplied to the inside of the power transmission mechanism 27. The prime mover 29 includes a fan for cooling the prime mover 29 with air. The air intake port 45 of the fan is disposed behind the concave surface 49 of the pedal portion 22. With this configuration, it is possible to surely ensure that the prime mover 29 cools the air. The air intake port 45 of the fan is open to the left or right in the lateral direction. At least the rear side and the lower side of the empty rolling inlet 45 include an air introduction wall 33 that protrudes in the lateral direction. The air introduction wall 33 guides the air flowing in along the concave surface 49 to the fan.
