At the part of the outer surface of the display ring where the angular position differs in the circumferential direction, two different display parts are provided with different colors to correspond to the locked state and the unlocked state, respectively, and inside the inner peripheral surface of the display ring. A floating notch is formed over a certain angle range, and a hook that protrudes in the radial direction and movably engages with the floating notch is provided at the outer end of the outer peripheral surface of the inner cylinder.
On the other hand, an outer cylinder cap having a shallow cup-shaped bottom and an opening on the bottom surface for viewing the outer end surface of the inner cylinder and a display hole for viewing the display portion of the display ring is attached so as to cover the outer end of the cylinder lock. At the initial stage of the lock operation, only the hook is allowed to float in the floating notch while leaving the display ring, and the hook is engaged with the end of the floating notch during the locking / unlocking operation, and thereafter the inner cylinder and the display ring are integrated. The display part in the display hole is switched by rotating the display part.

る。In the locking / unlocking display device according to the present invention configured as described above, a duplicate key (not shown) is inserted into the keyhole 17 (see FIG. 1), all tumblers are aligned with the shear line, and then the duplicate key is rotated clockwise or counterclockwise. For example, if you turn 180 degrees in the direction,
Together with this, the inner cylinder 2 rotates in the locking direction or the unlocking direction.
【００２３】このとき、回動の初期の段階では内筒のツ
ク９は遊動切欠８内で遊動するのみなので、例えば回し
始めから９０度の角度範囲では内筒２のみが回動して表
示リング３は当初の角度位置に残される。At this time, in the initial stage of the rotation, since the hook 9 of the inner cylinder only moves in the floating notch 8, for example, only the inner cylinder 2 is rotated in the angle range of 90 degrees from the start of the rotation to rotate the display ring. 3 is left in the original angular position.
