CYLINDER LOCK WITH LOCK/UNLOCK DISPLAY FUNCTION
PROBLEM TO BE SOLVED: To provide a cylinder lock with a lock/unlock display function, which prevents external force from acting on a cam fitted in an inner cylinder when unauthorized external force is acted on a display member, prevents unauthorized unlock without exposure of an internal configuration part of the cylinder lock even when the display member is destroyed, and is excellent in workability, etc. since a display part is made easy to see by increasing size of the display member, and it is necessary to process only a fitting hole of a cylinder as for a notch hole of a door.SOLUTION: In a locked state, an engaging part 14 of a display member 10 is engaged into an engaging receiving part 31a of a cam 30, when force for rotating the cam 30 in an unlock direction is acted on by unauthorizedly operating the display member 10 from an outdoor side, the locked state is held since engagement between the engaging part 14 of the display member 10 and the engaging receiving part 31a of the cam 30 is released, the cam is not rotated, and a hub of a lock case is not actuated.
【課題】表示部材に不正な外力を作用させた時、外力を内筒に嵌装したカムに作用しないようにし、また表示部材を破壊されても、シリンダー錠の内部構成部が露出することはなく、不正解除を防止する。表示部材を大きくして表示部を見易くし、扉の切欠穴は、シリンダーの取付穴のみを加工するだけでよく、施工性に優れる等の施解錠表示機能付きシリンダー錠を提供する。【解決手段】施錠状態時において、表示部材１０の係合部１４はカム３０の係合受部３１ａに係合されており、室外側から表示部材１０を不正に操作して、カム３０を解錠方向に回動させる力が作用した時には、表示部材１０の係合部１４はカム３０の係合受部３１ａとの係合が解除され、カムは回動されず錠ケースのハブは作動されないので、施錠状態が保持される。【選択図】図７
