To provide a door opening operation tool that provides ease of door opening operation by foot and safety of passage in a compatible manner.SOLUTION: A door opening operation tool, including a base 2 formed with a pair of bearing flanges 6 and fixed to a door D, a first shaft body 3 inserted into the bearing flanges 6, a second shaft body 4 provided adjacent to the first shaft body 3, and a raising arm 5 connecting the first shaft body 3 and the second shaft body 4 so that the second shaft body 4 can raise and lower around the axis of the first shaft body 3, in which the raising arm 5 can raise and lower between a stowed state where the second shaft body 4 approaches the door D and a raised state where the second shaft body 4 leaves the door D and a user operates the door D to open.SELECTED DRAWING: Figure 1
【課題】足による開扉操作の容易性と、通行の安全性の両立を図った扉の開扉操作具を提供する。【解決手段】一対の軸受フランジ６が形成され、扉Ｄに固定されるベース２と、軸受フランジ６に挿通される第一軸体３と、第一軸体３と隣り合って設けられる第二軸体４と、第二軸体４が第一軸体３の軸周りに起伏可能に、第一軸体３と第二軸体４を連結する起伏アーム５と、を有し、第二軸体４が扉Ｄに接近した収納状態と、第二軸体４が扉Ｄから離れて使用者による扉Ｄの開扉操作を行う起立状態との間で、起伏アーム５を起伏可能とする。【選択図】図１
