<P>PROBLEM TO BE SOLVED: To improve the visibility of the locked/unlocked state of a suspension lock which is attached to a door for opening and closing an entrance of a wall panel for partitioning indoor and outdoor sides, makes the door locked and unlocked by a lever swinging operation from the indoor side, and displays the locked/unlocked state of the door at the outdoor side using a display body which rotates in conjunction with a lever. Ž<P>SOLUTION: The operation of interlocking the lever 10 with the display body is performed via a driving shaft 30 which passes through the indoor and outdoor sides and rotates integrally with the lever 10, and a driven shaft 50 which is supported almost in parallel with an outdoor side surface and rotates in conjunction with the driving shaft 30 by meshing bevel gears 31 and 52. A half-split oval spherical display drum 51 which is integrally rotated using the driven shaft 50 as a rotating shaft is adopted as the display body. The locked/unlocked of a suspension lock is displayed on the outdoor side through a display window 61 which is opened on the upper half portion of a half-split oval spherical cover 60 for covering the display drum 51. The three-dimensional display drum 51 which rotates on the rotating shaft parallel to the outdoor side surface can be easily checked from a view point obliquely above the cover 60 in the outdoor front.
