LOWER PART SWING STOPPER OF HANGING DOOR

To provide a lower part swing topper of a hanging door capable of holding a guide piece securely and guiding the hanging door stably while reducing a thickness of a floor surface installation member including the guide piece and removing a need to perform a process of drilling a floor surface where the floor surface installation member is installed.SOLUTION: A guide piece 4 is configured of a plate like member formed with a locking protrusion 41 protruding in a width direction on both side of a tip, a guide groove member 7 is configured to form an engage part 72 to which the locking protrusion 41 of the guide piece 4 is locked on both side of a guide groove 71 in a longitudinal direction of the guide groove 71 and a size W1 in a width direction of the tip formed with the locking protrusion 41 of the plate like member consisting of the guide piece 4 is configured to be smaller than a size W2 in a width direction of an aperture of the guide groove 71 of the groove member 7.SELECTED DRAWING: Figure 1 【課題】ガイド片の保持を確実にして吊り戸を安定的にガイドできるようにするとともに、ガイド片を含む床面設置部材の厚みを小さくし、床面設置部材を設置する床面に穴をあける等の加工を行う必要をなくした吊り戸の下部振止装置を提供すること。【解決手段】ガイド片４を、先端部の両側に幅方向に突出する係止突起４１を形成した板状部材で構成し、案内溝部材７を、案内溝７１の両側壁にガイド片４の係止突起４１が係止される係合部７２を案内溝７１の長手方向に形成して構成し、ガイド片４を構成する板状部材の係止突起４１を形成した先端部の幅方向の寸法Ｗ１が、案内溝部材７の案内溝７１の開口部の幅方向の寸法Ｗ２よりも小さく設定してなるようにする。【選択図】図１
