Zusammenfassung:PROBLEM TO BE SOLVED: To provide an opening limitation device with a key, an opening limitation device for limiting an opening angle of a sash, that prevents the sash from being fully opened even when an opening state of the sash at a limitation position is released by erroneous operation.SOLUTION: A slider 8 for limiting an opening angle of a sash 1 is fitted on a fixation arm; a locking device 9 is slidably provided adjacently to the slider. The locking device includes a lock 29 to be operated using a key; using the lock, a lock piece 23 is moved to be engaged with a locking groove 20 provided on the fixation arm to fix the locking device on the fixation arm. A display part 27 of the lock piece 23 sinks in the inside of the locking device 9 when the lock piece is engaged with the locking groove 20; and protrudes from the exterior surface of the locking device 9 when the lock piece escapes from the locking groove 20, showing an unlocked state.SELECTED DRAWING: Figure 3 【課題】障子の開口角度を制限する開口制限装置において、制限位置にある障子の開口状態が誤動作により解除されても障子が全開しないようにしたキー付き開口制限装置を提供する。【解決手段】障子1の開口角度を制限するスライダー8を固定アームに嵌着し、このスライダーに隣接して施錠装置9を摺動可能に設ける。施錠装置はキーで操作する錠29を有し、この錠によりロック片23を移動させて固定アームに設けた係止溝20に係合させ、施錠装置を固定アームに固定する。ロック片23の表示部27は、ロック片が係止溝20に係合しているとき施錠装置9内に没入し、係止溝20から脱出しているとき施錠装置9の外面から突出し、解錠状態を示す。【選択図】図3
