To provide a door stopper 10 whose leg part 30 fitted in a groove 7 of a vertical frame 2 of a door frame 1 is not separated from the groove 7 by an impact force applied from a door 5.SOLUTION: A base end part 31 of a leg part 30 connected to a side part 21 of a door stop body 20 with which a door 5 collides has an outer convex part 32 facing a first inner surface 11 on the upstream side in a closing movement direction 6 within a groove 7, and a support convex part 33 facing a second inner surface 12 on the downstream side. A tip part 41 connected to the base end part 31 by a connecting part 45 has an elastic convex part 42 elastically abutting on the first inner surface 11, and an inner convex part 43 abutting on the second inner surface 12. Upon collision with the door 5, the support convex part 33 abuts on the second inner surface 12 and serves as a fulcrum, generating a moment in the clockwise direction indicated in FIG. 3, and the elastic convex part 42 is crushed and deformed by the first inner surface 11, which increases the contact area with the first inner surface 11, thereby increasing the frictional force and preventing detachment.SELECTED DRAWING: Figure 1
【課題】ドア枠１の縦枠２の溝７に嵌め込まれる脚部３０が、ドア５の衝撃力によって溝７から離脱しない戸当り具１０を提供する。【解決手段】ドア５が衝突する戸当り本体２０の側部２１に接続される脚部３０の基端部３１は、溝７内で閉移動方向６の上流側の第１内面１１に臨む外凸部３２と、下流側の第２内面１２に臨む支持凸部３３とを有する。基端部３１に連結部４５によって連結される先端部４１は、第１内面１１に弾発的に当接する弾性凸部４２と、第２内面１２に当接する内凸部４３とを有する。ドア５の衝突によって、支持凸部３３は第２内面１２に当接して支点となって図３の時計方向のモーメントが発生し、弾性凸部４２は第１内面１１に押し潰されて変形し、第１内面１１との接触面積が増大して摩擦力が増大し、離脱が防がれる。【選択図】 図１
