PROBLEM TO BE SOLVED: To easily lock and unlock a hinged door without using a joint part between panels at all while obtaining beauty of a plane free of a projection such as a handle on an outer side of a wall body constructed in plane by arraying a plurality of panels.SOLUTION: A tip part 40b of a guide pin 40 of guide means G is locked in a guide groove 35 cut in a slider 30. When the slider 30 moves back against an energizing spring 50 by pressing a hinged door to be closed, the tip part 40b of the guide pin 40 is guided to a first latch position through a going passage "a" of the guide groove 35 to lock the slider 30. When the hinged door to be opened is pressed again, the slider 30 to be unlocked moves forward with spring restoring force of the energizing spring 50, and the tip 40b of the guide pin 40 is guided to a second latch position through a return passage "d" of the guide groove 35 to lock the slider 30, a stroke L of linear going/return movement of the slider 30 between the first latch position and second latch position being set according to a door thickness of the hinged door D. |
