<p>PROBLEM TO BE SOLVED: To provide a technique to stabilize movement of a lock device, even when fire breaks out on whichever side in the depth dimension of a fitting.SOLUTION: A fitting comprises: a frame body 20 provided in an opening part 11 of a building; a screen 30 tiltably attached to the frame body 20 and allowing the opening part 11 to open/close by the tilting thereof; and a lock device 100 arranged inside a hollow part 29, which is formed by being surrounded by the frame body 20 and the screen 30, when the screen 30 is in a closed state, for keeping the screen 30 in the closed state when fire breaks out. The lock device 100 is attached to an attached part 113 provided in the frame body 20, and includes: a moving member 120 movable from a first position to a second position; and a holding tool 140 for holding the moving member 120 in the first position. When fire breaks out, the holding tool 140 melts to allow the moving member 120 to move by the gravity from the first position to the second position. When the screen 30 tilts toward the opening position, the moving member 120 is engaged with a receiving part 73 in a case of being in the second position.</p> |
