<p>A cylinder lock comprising a tubular sleeve (17) having a lock groove (18) in the inner circumferential surface, a tubular cylinder (21) having a plurality of tumbler insertion holes (23), a plurality of tumblers (27) engaging with the lock groove (18) at an advanced position and retracting to disengage from the lock groove (18) when a regular key is inserted, a rear rotor (32) at least a part of which is arranged rotatably in the cylinder (21) and having a containing part (35) at the part being arranged in the cylinder (21), a coupling member (40) arranged in the containing part (35) of the rear rotor (32) and movable radially between positions for coupling/uncoupling the rear rotor (32) and the cylinder (21), and an uncoupling member (44) arranged to move radially with respect to the sleeve (17) such that it is positioned at the outer circumferential part of the coupling member (40) and moving in the radial direction when the sleeve (17) receives a rotating force of the cylinder (21) through engagement with the tumbler (27) and rotates with respect to a holder (10) thus pushing and moving the coupling member (40) to an uncoupling position.</p> |
