PROBLEM TO BE SOLVED: To provide a disk tumbler cylinder type cylinder lock for improving safety against fraudulent manipulation, particularly picking.SOLUTION: The disk tumbler cylinder type cylinder lock comprises a cylinder housing (11) and a cylinder core (13) provided rotatably within the cylinder housing. A plurality of disk tumblers (21) each including at least one engagement parts (25, 27) is provided within the cylinder core. At least one of the disk tumblers has toothed regions (35, 37). The toothed regions are engageable with an opposed toothed region (63) of the cylinder lock, so as to prevent the movement in a direction opposite to a corresponding bias direction (X) of the disk tumblers (21) when the disk tumblers are located at a locking position and a torque in a rotary unlocking direction is applied to the cylinder core. |
