PROBLEM TO BE SOLVED: To provide a key code conversion-type disc tumbler lock capable of reducing the number of components by a simple structure. SOLUTION: This disc tumbler lock includes: an outer cylinder 2 which forms an outer shell of the lock; an inner cylinder 3 which is rotatably inserted into the outer cylinder 2, in which a key insertion hole 31 is axially provided, and in which a plurality of tumbler insertion holes 32 are provided in such a manner as to communicate with the key insertion hole in a direction perpendicular to the key insertion hole 31; and first and second disc tumblers 6 and 7 which are slidably inserted into the tumbler insertion holes 32, respectively. The first lock member 4 is mounted in a radially slidable manner in a first locking groove 34 which is provided in the outer peripheral portion of the inner cylinder; and a second lock member 5 is mounted in a radially slidable manner in a second locking groove 35. The first and second lock members 4 and 5 can have leading ends fitted into a locking groove 21 formed in the inner peripheral surface of the outer cylinder. COPYRIGHT: (C)2011,JPO&INPIT
