To disclose an example of a window open/close device capable of realizing an opening degree 0 state in which a window opening is fully closed, a state in which the opening degree is fixed at the maximum opening, and a state in which the opening degree changes from approximately 0 to approximately the maximum opening depending on the wind pressure.SOLUTION: A window open/close device includes: an open/close arm 7 swinging between a first position that exerts a force to a sash 3 to thereby causing the sash 3 to swing toward the closed position side and a second position that exerts a force to the sash 3 to thereby causing the sash 3 to swing toward the open position side; a pressure receiving portion 8 configured to swing for displacement integrally with the sash 3 and configured to contact with a tip end portion 7A of the open/close arm 7 when the open/close arm 7 is positioned at the first position or the second position to receive a force for swinging; and an operating mechanism having a holding function to hold the open/close arm 7 at a third position between the first position and the second position and causing the open/close arm 7 to swing between the first position and the second position. The open/close arm 7 is put into the noncontact state with the pressure receiving portion 8 when the open/close arm 7 is positioned at the third position.SELECTED DRAWING: Figure 5
【課題】 窓開口が閉じられた開度０の状態、開度が最大開度に固定された状態、及び風圧に応じて開度略０から略最大開度までの間で変化する状態を実現可能な窓開閉装置の一例を開示する。【解決手段】 障子３を閉位置側に揺動させる力を障子３に作用させる第１ポジションと障子３を開位置側に揺動させる力を障子３に作用させる第２ポジションとの間で揺動する開閉アーム７と、障子３と一体的に揺動変位するとともに、開閉アーム７が第１ポジション又は第２ポジションに位置する際に開閉アーム７の先端部７Ａに接触して「揺動させる力」を受ける受圧部８と、開閉アーム７を第１ポジションと第２ポジションとの間の第３ポジションに保持する保持機能を有するとともに、開閉アーム７を第１ポジションと第２ポジションとの間で揺動させる操作機構とを備え、開閉アーム７が第３ポジションに位置したときには、開閉アーム７は、受圧部８と非接触状態になる。【選択図】 図５
