PURPOSE:To improve the cooling efficiency of a clutch and to stabilize its durability and function by sealingly housing said clutch in a crankcase while interposing it in the cooling water route system of an engine. CONSTITUTION:A clutch 2 is sealingly housed in a clutch chamber, which is formed in a certain position of a crankcase 1. Cooling water 10 fed from the cooling water route system of an engine is filled in the clutch chamber, and then is discharged to a radiator 22 side. Thus, in order to cool the clutch, part of cooling water for cooling a water-cooled engine is filled into the clutch chamber, and furthermore, this cooling water is cooled by the radiator of the water-cooled engine, thereby improving the cooling efficiency of the clutch, and stabilizing the function of the clutch. |
