PROBLEM TO BE SOLVED: To provide a draining structure of an electric two-wheel vehicle which reliably prevents water components and dust flying during traveling from entering into a space for housing electric and electronic devices, such as a motor and an inverter, while securing air permeability and drainage in a swing arm.SOLUTION: A draining structure of an electric two-wheel vehicle 1 includes: a hollow swing arm body 65 supporting a rear wheel; an inverter 18 housed in the swing arm body 65; a motor 3 which is housed in the swing arm body 65 and rotationally drives the rear wheel with electric power supplied from the inverter 18; a breather cap 92 which is provided at an upper part of the swing arm body 65 and balances an internal/external pressure difference of the swing arm body 65; a drain 95 which is provided at a lower part of the swing arm body 65 and has a draining hole 93 for draining water components in the swing arm body 65; and a drain plug 96 detachably attached to the drain 95.SELECTED DRAWING: Figure 5
【課題】スイングアーム内の通気性と排水性を確保しつつ、走行時に飛沫する水分や塵などが、モータやインバータなどの電気、電子機器を収納する空間に侵入することを、確実に阻止できる電動二輪車の水抜き構造を提供する。【解決手段】電動二輪車1の水抜き構造は、後輪を支持する中空なスイングアーム本体65と、スイングアーム本体65内に収容されるインバータ18と、スイングアーム本体65内に収容されてインバータ18から供給される電力で、後輪を回転駆動させるモータ3と、スイングアーム本体65の上部に設けられて、スイングアーム本体65の内外圧力差を均衡させるブリーザキャップ92と、スイングアーム本体65の下部に設けられて、スイングアーム本体65内の水分を排出する水抜き孔93を有するドレーン95と、ドレーン95に着脱自在に装着されるドレーンプラグ96と、を備えている。【選択図】図5
