PROBLEM TO BE SOLVED: To provide a saddle-type vehicle capable of suppressing increase in the dimension of an engine when a breather device formed integrally with a cooling water pump is provided. SOLUTION: The straddle-type vehicle includes: a swing type engine unit 40 having a crankcase 90, a cylinder 80, and a cylinder head 70 in which a cam shaft 73 is disposed; the cooling water pump 74 which has an impeller 74a rotatably connected to the cam shaft 7 and supplying cooling water to cooling water channels and is provided in the cylinder head 70; and the breather device 75 which is disposed adjacent to the cooling water pump 74 and through which an impeller shaft 74b passes. The breather device 75 includes a breather chamber S1 having a length along the cylinder center line C1 larger than that of the cooling water pump 74. The breather chamber S1 is positioned further toward the crankcase 90 with respect to the cam shaft 73. COPYRIGHT: (C)2008,JPO&INPIT
