The present invention ensures a large gap in front of a supply port at a fully open position of a cover without changing the structure of each arm, and improves arm rigidity with respect to an external force at the fully open position of the cover. The vehicle cover opening and closing device includes: a base portion attached to a vehicle body; an opening that exposes a supply port for supplying energy to the vehicle; a cover that closes the opening; and a link mechanism that opens and closes the cover between a predetermined closed position and a predetermined open position. The link mechanism has first and second arms, one end of each of which is rotatably supported by the base and the other end of which is rotatably supported by the cover. The second arm rotates synchronously with the rotation of the first arm, and can be located within the rotation trajectory of the first arm when viewed in the thrust direction. The first and second arms each have: overlapping portions that overlap each other in the thrust direction at the cover opening position; and stoppers contacting each other in the rotational direction at the lid opening position to restrict further opening action of the lid.
不通过各臂的构造变化而将盖的完全打开位置处的供给口前的间隙确保得大且提高相对于盖的完全打开位置处的外力的臂刚性。车辆用盖开闭装置具有:基部,安装于车身;开口部,使得用于向车辆供给能量的供给口露出;盖,将开口部封闭;以及连杆机构,使得盖在规定关闭位置与规定打开位置之间进行开闭动作。连杆机构具有各自的一端部以能够转动的方式支撑于基部且另一端部以能够转动的方式支撑于盖的第一及第二臂。第二臂与第一臂的转动同步地转动,在推力方向上观察可以位于第一臂的转动轨迹内。第一及第二臂分别具有:重叠部,在盖打开位置处彼此在推力方向上重叠;以及止动部,在盖打开位置处彼此在转动方向上接触而限制盖进一步的打开动作。
