  • Publication number: 20190300091
    Abstract: A saddled vehicle includes: a vehicle body frame; an internal combustion engine supported at a lower portion of the vehicle body frame; a fuel tank supported at an upper portion of the vehicle body frame; and a canister. The canister is disposed around the fuel tank at a position lower than a seating portion of an occupant seat. A removable hermetic sealing cap or a one-way valve that prevents entry of rainwater from an outside is included in a drain pipe disposed at a lower portion of the canister. Accordingly, entry of rainwater into the canister is prevented with a simple structure.

  • Patent number: 10427744
    Abstract: A handling performance is improved by a fuel tank fitting structure. A fuel tank is mounted to a vehicle body frame at three points: a first fixed section with a bolt and two second fixed sections with two bolts. A grommet provided in the first fixed section has an interference. Each of the second fixed sections has a fitting clearance between a collar and the grommet, and an axial clearance between the collar and the grommet. These clearances enable the grommet without an interference and the fuel tank to relatively movable to the vehicle body frame. The fuel tank and a vehicle body thus have different behaviors during cornering, thereby obtaining reduced inertial weight and light handling.
