PURPOSE: To bear a high locking load by pivotally installing a locking member in the recess section of a tumbler pin and performing locking at a position in front of a stop of a cylinder case.
CONSTITUTION: When a key 15 is inserted into a cylinder core 11, a coil 21 is connected to a power source, and the N pole and S pole are formed in the pole 22' and pole" of a C-shaped armature respectively rotating a locking member 33. In the next step, a locking edge section 39 moves to a position in front of a stop 38' to prevent a tumbler pin 23 from displacing. Then, an electronic state is recognized by a reading device. If the key 15 is correctly positioned, the locking member is returned to a neutral position by a permanent magnet 35, and the N and S poles of the magnet 35 face to core pieces 36 and 37. In addition, while a cylinder pin 11 is being twisted, the tumbler pin 23 is driven downward by a locking notch 31, and a compression spring 29 is compressed for locking.
