PROBLEM TO BE SOLVED: To provide a canister arrangement structure for a motor cycle, capable of suppressing canister performance deterioration and utilizing a dead space efficiently.SOLUTION: An arrangement structure of a canister 30 for a motor cycle 1 comprises: a vehicle body frame 2 including a main frame 11 extending rearward from a head tube 10 and a down tube 12 extending downward from the head tube 10; an engine 3 mounted on the vehicle body frame 2 and including a cylinder 21 extending upward from a crank case 20; a fuel tank 4 for storing fuel to be supplied to the engine 3; and a canister 30 for temporarily capturing vaporized fuel generated in the fuel tank 4. The fuel tank 4 is disposed so as to stride over the main frame 11 on a recess part 4b which becomes dent from a lower face 4a to upward, and the canister 30 is disposed between the down tube 12 and cylinder 21, and in the recess part 4b of the fuel tank 4.

    【課題】デッドスペースを有効に利用し、キャニスターの性能低下を抑制する自動二輪車のキャニスター配置構造を提供する。【解決手段】本発明の自動二輪車1のキャニスター30の配置構造は、ヘッドパイプ10から後方に延びるメインフレーム11と、ヘッドパイプ10から下方に延びるダウンチューブ12と、を含む車体フレーム2と、車体フレーム2に搭載され、クランクケース20から上方に延びるシリンダー21を含むエンジン3と、エンジン3に供給される燃料を貯留する燃料タンク4と、燃料タンク4内で発生した蒸発燃料を一時的に捕集するキャニスター30と、を備え、燃料タンク4は、下面4aから上方に向けて窪む凹部4bにおいてメインフレーム11を跨いで配置され、キャニスター30は、ダウンチューブ12とシリンダー21との間で、且つ、燃料タンク4の凹部4bの内側に配置される。【選択図】図5
