To allow a door closing auxiliary operation to be securely performed in a door closing auxiliary device that assists door closing operation by engaging a pulling arm of a device body fitted to one of a door frame and a revolving door with a trigger fitted to the other.SOLUTION: A pressing surface 18b of a first spring case 18 of an energizing mechanism 4 abutting with a pressure receiving roller 15 of a pulling arm 3 consists of an arm holding surface 18b1, which is orthogonalized with an energizing direction of the energizing mechanism 4 and abuts with the pressure receiving roller 15 of the pulling arm 3 at a standby position, and an inclined plane 18b2 continuing to the arm holding surface 18b1. A change point (straight line A) of the energizing mechanism 4 is positioned in the middle of the inclined plane 18b2. A contact point between the pressure receiving roller 15 and the first spring case 18 can easily pass on the change point of the energizing mechanism 4. Consequently, even if a force added to the door when closing the door is small, the pulling arm 3 securely rotates in a pull-in direction and allows door closing auxiliary operation to be performed.SELECTED DRAWING: Figure 5
【課題】扉枠と回動式の扉の一方に取り付けた装置本体の引込アームと他方に取り付けたトリガーとを係合させて扉の閉止動作を補助する扉閉止補助装置において、その扉閉止補助動作がより確実に行われるようにする。【解決手段】引込アーム３の受圧ローラ１５と当接する付勢機構４の第１ばねケース１８の押圧面１８ｂを、付勢機構４の付勢方向と直交し、待機位置にある引込アーム３の受圧ローラ１５と当接するアーム保持面１８ｂ１と、アーム保持面１８ｂ１に連続する傾斜面１８ｂ２とからなり、その傾斜面１８ｂ２の途中に付勢機構４の思案点（直線Ａ）が位置するものとして、受圧ローラ１５と第１ばねケース１８との接点が付勢機構４の思案点を乗り越えやすくした。これにより、扉を閉じるときに扉に加える力が小さい場合でも、確実に引込アーム３が引込方向に回動して扉閉止補助動作を行うことができる。【選択図】図５
