Summary:To reduce the size by reducing a load when opening and closing a prime mover cover with a single spring member.SOLUTION: A spring member 12 provided between a battery bracket 6 constituting a vehicle body and a prime mover cover 8 to assist an opening/closing operation of the prime mover cover 8 is formed as a tension spring. On this, the spring member 12 is provided so as to be in the minimum contracted state when a center-of-gravity position G of the prime mover cover 8 is arranged on a vertical line V of a rotation center O of the prime mover cover 8.SELECTED DRAWING: Figure 3 【課題】 １本のばね部材によって原動機カバーを開閉するときの負荷を軽減することにより、小型化できるようにする。【解決手段】 原動機カバー８の開閉動作を補助するために、車体を構成するバッテリブラケット６と原動機カバー８との間に設けられたばね部材１２は、引っ張りばねとして形成されている。この上で、ばね部材１２は、原動機カバー８の重心位置Ｇが原動機カバー８の回動中心Ｏの鉛直線Ｖ上に配置されたときに、最縮小状態となるように設けられている。【選択図】 図３
