The present invention provides a cylinder lock that is capable of preventing a driver pin from falling over inside a pin hole even when the driver pin has been shortened. The cylinder lock comprises an outer cylinder and an inner cylinder that rotatably fits into the outer cylinder. The outer cylinder and the inner cylinder each have a hole formed therein which connects to a key hole and into which the driver pin can be inserted. The diameter of the outer cylinder side of the driver pin is greater than the diameter of the inner cylinder side of the driver pin. An orientation-maintaining region having a prescribed length in the axial direction and a fixed diameter is preferably provided at the outer cylinder–side end of the driver pin.
