To provide a simple chassis type electric vehicle capable of floating and climbing over a protruded step in a stable state though having a wheel with a small diameter, realizing a small-turn performance of the vehicle with a simple mechanism, and reducing a vehicle body weight by not using an elastic body for impact absorption.SOLUTION: A skeleton frame structure includes: a main chassis extending in the longitudinal direction; a seat frame placed on and connected to its rear part; right and left side pipes extending to the right and left rear sides with approximately L-shapes from a front part of the main chassis; rear wheel right and left support pipes extending to the right and light rear sides with approximately L-shapes from a front part of the seat frame; a lateral axis pipe horizontally laid in the middles of the rear wheel right and left support pipes; and a pivot part by which rear ends of the right and left side pipes are pivotally supported to the lateral axis pipe. A steering shaft is rotatably protruded diagonally upward from a tip end part of the main chassis. Right and left front wheels are provided on the tip end part through a front wheel steering mechanism interlockingly installed consecutively.SELECTED DRAWING: Figure 3

    【課題】簡易シャシー型で構成した電気自動車において、車輪を小径としながらも凸部段差の浮上乗り越えを安定した状態で実現すると共に、簡易機構にて車両の小回り性能を実現し、また、衝撃吸収のための弾性体を使用しないことで車体重量を低減する電気自動車を提供する。【解決手段】前後方向に伸延したメインシャシーと、その後部に載置連結したシートフレームと、メインシャシーの前部から左右後方に略L字状に伸延した左右サイドパイプと、シートフレーム前部から左右後方に略L字状に伸延した後車輪左右支持パイプと、後車輪左右支持パイプの中途に横架した横軸パイプと、横軸パイプに左右サイドパイプ後端を枢支した枢支部とでスケルトンフレーム構造を構成すると共に、メインシャシーの先端部より斜め上方に回転自在に操向軸を突設し、その先端部に連動連設した前輪操舵機構を介して左右前車輪を配設することを特徴とする。【選択図】図3
