Air-cleaner structure of saddle-ride type vehicle

An air-cleaner structure of a saddle-ride type vehicle, comprising an air-cleaner case placed between an occupant seat and a head pipe located forward of the occupant seat,

• wherein
• the air-cleaner case includes a bottom half and a top half, the bottom half being disposed in a space surrounded by a rear face of the head pipe and a pair of left and right frame members extending from the head pipe toward a rear of the saddle-ride type vehicle, the top half being situated above the frame members,
• the top half is formed in a vertical two division structure, the vertical two division structure of the top half having a dividing surface inclined in a longitudinal direction of the saddle-ride type vehicle,
• the top half is provided with an intermediate case joined to the bottom half and an upper case attached to a top face of the intermediate case, an opening is formed in an underside of the upper case, an upper-case flange protruding outward of the opening is formed at a bottom edge of the upper case, and a mating surface between the upper-case flange and the intermediate case is the dividing surface along which the top half is divided vertically into two,
• an air-cleaner element is mounted along the dividing surface,
• the dividing surface is inclined upwardly toward a front of the saddle-ride type vehicle at a larger angle than an inclination of an extension plane of a rotation path of a top bridge of the saddle-ride type vehicle supporting a front fork in a position above the head pipe, the dividing surface is arranged to cross the extension plane, and a front end of the upper-case flange is situated upward of the top bridge to provide a clearance in an up-down direction of the saddle-ride type vehicle between the front end of the upper-case flange and the top bridge,
• the upper-case flange of the top half is formed in a trapezoidal shape with a long side on a front side of the saddle-ride type vehicle in top view,
• the air-cleaner element includes a frame and a filter supported on inner sides of the frame, and
• the frame is formed in a trapezoidal shape with a long side on the front side in top view corresponding to the trapezoidal shape of the upper-case flange of the top half.
