PROBLEM TO BE SOLVED: To provide a cylinder lock which does not allow picking in terms of a mechanism, whose number of key combinations is larger than that of a conventional cylinder lock by at least ten thousands, and can perform a key-combination change operation of a lock at a cylinder lock user side.SOLUTION: An inner cylinder 7 which is cylindrical in shape as a whole, and whose both ends are slidably fit into center holes of receiving plates between first and second receiving plates is arranged between first and second receiving plates 3, 4 which are fit to one end and the other end of a cylindrical outer cylinder 1, an external peripheral part of the inner cylinder is wound around by n-pieces (n: positive number) of tumbler pins 13, 13 which are energized to a direction in which the pins are fit into pin receiving holes corresponding to the first receiving plate, and parallel with a bus bar so as to be surrounded by the pins, the inner cylinder is anchored to the first receiving plate by locking the tumbler pins into the corresponding pin receiving holes by prescribed amounts at locking, one-side ends of the tumbler pins are removed from the corresponding receiving holes of the first receiving plate by protrusive teeth 29 formed at an opening edge of a pipe-shaped duplicate key 27 at lock-releasing, and the inner cylinder is made to be relatively turnable with respect to the outer cylinder.
【課題】 ピッキングが機構上できず、また、鍵違いが従来のシリンダー錠に比べて少なくとも1万倍多く、しかも、シリンダー錠使用者側における錠前の鍵違い変更操作が可能なシリンダー錠を提供する。【解決手段】 円筒形の外筒1の一端と他端とに夫々嵌装された第1及び第2受板3、4の間に、全体の形状が円筒状で、上記第1及び第2受板の間において両端部を受板の中心孔に摺動可能に嵌合させた内筒7を設け、この内筒の外周部を、第1受板の対応するピン受け穴に嵌入する方向に付勢され、母線に平行なn(n:正整数)本のタンブラーピン13、13により包囲するように卷装し、施錠時、各タンブラーピンを対応するピン受け穴に所定量係入させて内筒を第1受板に錨止し、解錠時、パイプ状の合鍵27の開口端縁に形成された突歯29により各タンブラーピンの一端を第1受板の対応する受け穴から抜去して、内筒を外筒に対し相対回動できるようにした。【選択図】 図1
