<p>A layout structure for a cooling duct for a stepless transmission of a straddle-riding type vehicle achieves high degrees of freedom in layout and design of portions around the cooling duct with a sufficient amount of cooling air supply in the duct assured. In the layout structure, a part of the cooling duct (43) is mounted so as to extend along a main pipe (12) and a rear frame (14) with a bend (80C) of the cooling duct located at the joint between the main pipe (12) and a rear upper pipe (14A). A suction opening (65) of the cooling duct (43) is connected to a side wall of a housing box (27) after passing through between the rear upper pipe (14A) and a rear lower pipe (14B). The layout structure facilitates fastening of a suspension section (90) of an engine (51) equipped with a belt converter cooling duct and is constructed without an increase in the weight of an engine hanger (50A).</p> |
