However, if it becomes necessary to rearrange the cylinder lock, one end should be formed straight from the keyhole and the other end should be straightened. A fork-shaped pin having a hook-shaped tip at its tip is inserted to prevent the straight portion from coming off and to engage with the pin engagement hole of the tumbler, and the hook-shaped portion is locked to the tumbler engagement notch of the inner cylinder. Then narrow the tip of the pin, pull the retaining tumbler into the inner cylinder against the elastic force of the spring, and pull up the pin while releasing the fitting with the concave part of the outer cylinder,
The inner cylinder having the tumbler engaging notch portion locked to the hook-shaped portion can be removed from the outer cylinder.
