PROBLEM TO BE SOLVED: To provide an effective picking preventive mechanism for a cylinder lock. SOLUTION: At least two out of a key guide 14, a partition plate B22 and a tail plug 15 constituting an inner cylinder 13 of the cylinder lock are selected and made guide members. A pair of guide grooves 23, 23 disposed parallel with each other with a support shaft 3 held in between and communicating on one end side with a keyhole, are formed at the mutually opposed faces of the guide members. A search pin 24 is enclosed in each guide groove 23 movably in the lengthwise direction of the search pin 24. A control body 26 having a locking face close to the base end part of a tumbler is engaged with the search pin 24 so that each of a pair of connecting projections 27 protrusively provided at the front end and rear end is inserted in the other end part of the guide groove 23.
