To provide a lock device for a gate door which avoids an operation lever interfering with a jamb of an adjacent door.SOLUTION: In a structure where a slit 8a for allowing guide pieces 5c, 6c, 6d of guide parts 5, 6 for insertably supporting a drop bar 3 to be inserted is formed in an operation lever 8 extended in a radial direction from the drop bar 3, rotation direction restriction means is provided for inhibiting the rotation of the operation lever 8 to an adjacent door side. In the rotation direction restriction means, a rotation inhibition member 10 for inhibiting the rotation of the operation lever 8 to the adjacent door side may be provided at the guide pieces 5c, 6c of the adjacent door side, or the rotation inhibition part for inhibiting the insertion of the operation lever 8 into the slit 8a may be integrally formed. Also, a cylindrical member may be provided for restricting the movement of the operation lever 8 between the drop bar 3 and the guide parts 5, 6.SELECTED DRAWING: Figure 1
【課題】操作レバーが隣接する扉の縦枠と干渉することを回避させる門扉用施錠装置を提供する。【解決手段】落とし棒３から径方向に延設され操作レバー８に、落とし棒３を挿通可能に支持するガイド部５，６のガイド片５ｃ、６ｃ、６ｄを挿通可能とするスリット８ａが形成されている構成において、操作レバー８の隣接する扉側への回動を阻止する回動方向規制手段を設ける。この回動方向規制手段は、隣接する扉側のガイド片５ｃ、６ｃに、操作レバー８の隣接する扉側への回動を阻止する回動阻止部材１０を設けても、操作レバー８のスリット８ａへの挿通を阻止する回動阻止部を一体に形成してもよい。また、落とし棒３とガイド部５，６と間に操作レバー８の動きを規制する筒状部材を設けてもよい。【選択図】図１
