Zusammenfassung:To arrange an internal combustion engine and a frame member close to each other with a clearance secured between a temperature rising part and the frame member in a fuel supply device in which the temperature rising part for heating a fuel continues into an injector to make the device itself compact.SOLUTION: A fuel supply device includes: a main frame 22 disposed above an engine 10 in a vehicle vertical direction and extending in a first direction (a vehicle fore and aft direction) when viewed from the vehicle vertical direction; an injector configured to inject a fuel to be supplied to the engine 10; a fuel chamber part 50 which is connected to the injector and configured to accumulate the fuel to be supplied to the injector; and a heater device 60 which is connected to the fuel chamber part 50 and heats the fuel accumulated in the fuel chamber part 50. The heater device 60 is disposed offset from the main frame 22 in a second direction (a vehicle lateral direction) orthogonal to the first direction when viewed from the vehicle vertical direction.SELECTED DRAWING: Figure 3 【課題】インジェクタに燃料を加熱する昇温部が連なる燃料供給装置において、昇温部とフレーム部材とのクリアランスを確保しながら内燃機関とフレーム部材とを近付けて配置し、機器自体をコンパクトにする。【解決手段】車両上下方向でエンジン10の上方に配置され、車両上下方向から見て第一方向(車両前後方向)に延びるメインフレーム22と、エンジン10に供給する燃料を噴射するインジェクタと、インジェクタに接続され、インジェクタに供給する燃料を溜める燃料チャンバ部50と、燃料チャンバ部50に接続され、燃料チャンバ部50内に溜めた燃料を加熱するヒータ装置60と、を備え、ヒータ装置60は、メインフレーム22に対して、車両上下方向から見て前記第一方向と直交する第二方向(車両左右方向)にオフセットして配置されている。【選択図】図3
