The display window 4 side of the display lock A is connected to the outside of the door, the light so that the latch bolt and the dead bolt enter and exit from the door side by the operation of the handle lever 2 and the thumb turn 3 of the display lock A, respectively. The introduction part 5 side is attached as the indoor side of the door. Here, the indoor side refers to a room side such as a toilet or bathroom that performs locking or unlocking operation from the room side, and the outdoor side refers to an opposite side of the room side, such as a corridor, across the door.

  The display lock A is attached in a shallow recess 7a provided on the surface of the mounting seat 7 so that the disk-shaped display portion 6 can be rotated in conjunction with the operation of the thumb turn 3, and is locked. The lock display 6a is displayed through the display window 4 provided in the cover member 8 in the unlocked state and the unlock display 6b in the unlocked state.

  In addition, a convex lens-shaped light introducing portion 5 is provided on the top of the thumb turn 3, and indoor light introduced from the light introducing portion 5 is displayed through the display window 4 from the back side of the light introducing portion 5. It passes through the cylindrical light passage portion 9 provided obliquely to the back surface side of the display portion 6 and the locked display portion 6a or the unlocked display portion 6b displayed on the display window 4 is made transparent. It is configured as follows.
