PROBLEM TO BE SOLVED: To provide an exterior structure of an electric two-wheel vehicle which can efficiently and surely cool a power conversion device which is arranged inside an outer sheath.SOLUTION: An exterior structure 71 of a fuel battery two-wheel vehicle comprises: a frame 11 extending to a fore-and-aft direction; a power conversion device 69 which is long in the fore-and-aft direction along the frame 11; and an outer sheath 12 which extends to the fore-and-aft direction, covers the frame 11 and the power conversion device 69, and defines a cooling wind passage 87 which makes a cooling wind circulate between the power conversion device 69 and itself along the fore-and-aft direction. The power conversion device 69 has a plurality of heat radiation fins 75 which extend toward the fore-and-aft direction in the cooling wind passage 87, and protrude toward an inner face of the outer sheath 12, and the outer sheath 12 has a wind introduction port which is arranged at a front end of the cooling wind passage 87, and makes a traveling wind flow into the cooling wind passage.SELECTED DRAWING: Figure 6

    【課題】外装の内側に配置される電力変換装置を効率良く、確実に冷却可能な電動二輪車用の外装構造を提供する。【解決手段】燃料電池二輪車用の外装構造71は、前後方向に延びるフレーム11と、フレーム11に沿って前後方向に長い電力変換装置69と、前後方向に延びてフレーム11および電力変換装置69を覆い隠し、かつ電力変換装置69との間に冷却風を前後方向に沿って流通させる冷却風路87を区画する外装12と、を備えている。電力変換装置69は、冷却風路87内で前後方向に向かって延び、かつ外装12の内面に向かって突出する複数の放熱フィン75を有し、外装12は、冷却風路87の前端に設けられて冷却風路に走行風を流入させる導風口を有している。【選択図】図6
