PROBLEM TO BE SOLVED: To provide a code change movement rotation mechanism of a magnetic card lock which can make smooth the rotation of a carrier which is a means of changing a code of a locking mechanism operated by a magnetic card, and which can obtain a rotation position with great precision. SOLUTION: The code change movement rotation mechanism consists of at least two carriers 15, and the carrier 15 is housed in a core slide member with possible rotation. Then a latch engagement member, which consists of four gradual raising parts all around the carrier on the periphery of the outside shape, is provided on one part of the periphery of the outside shape of the carrier in the lateral direction. A latch 14 fixed to a core hinge spring 13 is provided to the core slide member 11, and the latch 14 is provided so that it is engaged with the latch engagement member. Then an angle spring 16 incorporated into the carrier 15 is provided so that it can sandwitch a carrier shaft 18 which is provided to the core slide member 11, and the angle spring 16 is brought into contact with a cam 18a provided to the carrier shaft 18.
