Return to the state of 9.

  When the handle 5 is pushed into the handle case 2 in the state of FIG. 9, the dead bolt 15 is moved to the spring 24 at the position of FIG. 8 where the through opening 19 of the inner cylinder 3 and the engagement recess 20 of the handle case 2 face each other. When pushed, it automatically protrudes from the handle shaft 11 and engages with the engagement recess 20 to return to the state of FIG. At this time, the joint cam 17 is also pushed by the dead bolt 15 to return to the locked position. If the key is not removed from the lock in the state of FIG. 9, the joint cam 17 reverses as the dead bolt 15 protrudes, and the passive surface 48 pushes the drive engagement portion 25 to reverse the rotor cam 16. As a result, the unlocked rotor 14 automatically returns to the locked position, so that the key can be removed from the lock in this state.

  In the state of FIG. 6, even if an improper external force is applied in the direction of moving the dead bolt 15 to the unlocked position, the one end face 42 of the passive engagement portion 23 of the dead bolt 15 and the drive engagement portion 27 of the joint cam 17. And the joint cam 17 is not pushed to the unlocked position, and the dead bolt 15 is not pushed to the unlocked position.

  Although the dead bolt 15 is single, a security performance equal to or higher than that of a conventional structure incorporating two dead bolts in opposite directions can be obtained. Compared to the conventional structure, the structure is simple, the number of parts is small, and assembly is easy.
