PROBLEM TO BE SOLVED: To provide a lock that eliminates the necessity to remove an outer case when replacing a core and enables efficient replacement of an inner tube, thereby reducing the maintenance cost.SOLUTION: A lock with a replaceable core has structural designs such as a release recess 13 in an outer tube 10, a first sliding recess 14, a second sliding recess, an inner tube 20, and a lock tumbler 40. Thus, when the inner tube 20 is to be removed, a master key is inserted into the inner tube 20 until it abuts against a penetrated release member 41 and turned in the reverse direction, and the penetrated release member 41 is aligned with the release recess 13, thereby allowing the inner tube 20 to be drawn out of the outer tube 10.SELECTED DRAWING: Figure 3
【課題】芯を交換可能する際に、外筒を取り外す必要がなく、内筒を効率よく変更することが可能で、メンテナンスコストを抑えることができる錠前を提供する。【解決手段】芯が交換可能な錠前は、外筒１０の解除凹部１３、第一摺動凹部１４、第二摺動凹部、内筒２０、ロックタンブラー４０などの構造設計によって、内筒２０を取り外す時は、マスターキーを解除貫設部材４１に当接するまで内筒２０に挿し込んで逆方向へ回転させ、解除貫設部材４１を解除凹部１３に合わせると、内筒２０を外筒１０から引き抜いて取り外すことができる。【選択図】図３
