Abstract
In a straddle type vehicle in which a radiator is covered with a cover member, and an air guide duct for guiding hot air from the radiator to an outside of the vehicle is formed integral with the cover member, the hot air is restrained from staying within the cover member even in the case where the air guide duct of the cover member covering the radiator must be opened face-to-face with only a portion of a core of the radiator. A ventilation control member for controlling cooling air passing through the core of the radiator so as to flow toward an inner opening of the air guide duct is provided in the vicinity of the radiator.

A ventilation structure of a radiator in a straddle type vehicle, comprising:
- a radiator for cooling a coolant led from an engine body,
- a cover member provided on a lateral side of a vehicle body for covering the radiator,
- an air guide duct having an inner opening that is opened face-to-face with the radiator on the lateral side of the vehicle body and being formed integral with the cover member so as to guide hot air from the radiator outwardly of the vehicle,
- a ventilation control member attached to the radiator for controlling cooling air passing through a core of the radiator so as to flow toward the inner opening of the air guide duct,
- a grille arranged forward in a vehicle longitudinal direction of the ventilation control member and outwardly in a vehicle width direction of the radiator, the ventilation control member and the grille being interposed between the radiator and the air guide duct, and
- an extending wall integrally provided on the ventilation control member, the extending wall extending in a vehicle height direction along a rear outer periphery of the ventilation control member and in the vehicle width direction toward the air guide duct, the extending wall located rearward in the vehicle longitudinal direction of the inner opening and covered in a vehicle side view by a rear portion of the cover member,
- wherein the ventilation control member of a flat plate shape is formed integral with the grille, and a reticulated protrusion formed integral with a portion of the ventilation control member facing the air guide duct is connected to the grille.
A ventilation structure of a radiator in a straddle type vehicle, comprising:
- left and right radiators being adapted to cool a coolant led from an engine body and arranged on both front lower sides of a vehicle driver so as to be covered with a side cowl,
- a cooling air intake being adapted to guide traveling air to the radiators and provided between a pair of left and right side cowls and below a front cowl,
- an air guide duct having an inner opening that is opened face-to-face with the radiator from the outside in a vehicle width direction and being formed integral with the side cowl so as to guide hot air from the radiator in an outward direction of a vehicle,
- a grille arranged outwardly in the vehicle width direction of the radiator, and
- a ventilation control member for controlling cooling air passing through a core of the radiator so as to flow toward the inner opening of the air guide duct, wherein the ventilation control member is provided rearward in a vehicle longitudinal direction of the grille and outwardly in the vehicle width direction of the radiator, wherein the ventilation control member includes a base portion of a flat plate shape, the base portion is formed integral with and extends along a periphery of a rear portion of the grille in side view and has an outer surface coplanar with an outer surface of the grille,
- wherein the grille is formed in a reticulated shape defined by spaced projections extending outwardly in the vehicle width direction, the grille preventing foreign matter from entering the radiator side and arranged close to and face-to-face with the core of the radiator from the outside in the vehicle width direction, and a reticulated protrusion formed integral with a portion of the ventilation control member facing the air guide duct is connected to the grille.
