CAP OPENING/CLOSING STRUCTURE AND CHARGING CONNECTOR

To provide a cap opening/closing structure and a charging connector that can reduce a possibility of breakage.SOLUTION: A cap opening/closing structure 1A includes a housing 2, a cap 3 rotatably supported with respect to the housing 2, and a biasing member 43 that applies biasing force near a rotation shaft 42 of the cap 3, and at least one of a support portion 32 which is a sliding contact portion on a cap side and a sliding contact member 45 which is a sliding contact portion on a biasing member side is provided with open position maintaining means that maintains the cap 3 in the open position by the biasing force of the biasing member 43, and reaction force applying means that applies reaction force in the closing direction by the biasing member 43 to the cap 3 in response to the movement of the cap 3 in an opening direction from the open position.SELECTED DRAWING: Figure 4 【課題】破損の可能性を低減することができるキャップの開閉構造および充電用コネクタを提供すること。【解決手段】キャップの開閉構造１Ａは、ハウジング２と、ハウジング２に対して回動自在に支持されるキャップ３と、キャップ３の回動軸４２の近傍に付勢力を作用させる付勢部材４３と、を備え、キャップ側摺接部である支持部３２および付勢部材側摺接部である摺接部材４５のうち少なくとも一方には、付勢部材４３の付勢力によってキャップ３を開位置に維持させる開位置維持手段と、開位置からさらに開方向へのキャップ３の動きに対して付勢部材４３による閉方向への反力をキャップ３に作用させる反力作用手段と、が設けられている。【選択図】図４
