<p>PURPOSE:To prevent foreign matter such as water and mud, etc., from mixing into cooling air by providing an air intake port on a front cowling, and communicating an air intake port and a front surface of a cooling fan with a guide tube. CONSTITUTION:With a motor being operated and with a cooling fan being rotated in a cooling fan device 7, air is sucked into sent cooling air 26 to an engine 6. The air sucked as such is incorporated from the upper part of a front cowling 8 via an air intake port 9 and an air guide tube 23. Accordingly, the air does not include water and mud, etc., and is relatively clear, and hence the cooling air 26 supplied to the engine 6 does not include water and mud, etc., to prevent any fouling from being produced around a peripheral part of the engine 6.</p> |
