That is, the sliding door frame 2 has a pivot 11 in a direction parallel and horizontal to the glass surface (corresponding to the sliding door surface) P of the window glass 3.
Is installed, whereby the hook 12 is configured to be retractable from the sliding door frame 2 in the direction of the outdoor side O, and the end portion of the hook 12 on the indoor side I projects from the sliding door 1 to integrally form the operating portion 13. Has been done.

On the other hand, a locking metal fitting 14 (corresponding to the engaged portion) is fixed to the outer member 4, and the hook 12 is engaged when the operating portion 13 is operated to the locking position (the state shown in the first illustration). It is supposed to do.

Although not shown in FIG. 2, reference numeral 15 in FIG.
Locked position and unlocked position during operation (state shown in Fig. 2)
This is a compression spring device for providing a moderation with and preventing the hook 13 from loosening.

Further, in this embodiment, the emergency unlocking device 20 as described below is configured, and the emergency unlocking device 20 includes the sliding door frame 2
And an unlocking mechanism section 22 configured on the outer member 4.

The unlocking mechanism portion 21 formed on the sliding door frame 2 includes a pivot 23 supported by the sliding door frame 2 in parallel with the pivot 11 of the hook 13.
The link 24 is rotatably supported around the pivot axis, and one end of the link 24 is rotatably connected to a protrusion 25 formed integrally with the hook 12.

The other end of the link 24 has an advancing / retracting member described below.
It is connected to the rear end of 26. One of the connections at both ends of the hook 12 is a long hole, but the illustration is omitted.

The advancing / retreating member 26 is configured to be capable of projecting / retracting in a substantially vertical direction on the window glass surface P between a storage position (see FIG. 2) and an outer protruding position (see FIG. 1) in the sliding door frame 2. The outer member 4 is guided, and a through hole 27 is formed in the outer member 4 so that the tip of the advancing / retreating member 26 can enter the outer member 4 as shown in FIG.

The advancing / retreating member 26 configured as described above interlocks via the link 24 when the operating portion 13 is operated to the locking position, and advances to the inside of the outer member 4 as shown in FIG. When it is operated to the unlocked position, it is retracted to the storage position (FIG. 2) in the sliding door frame 2.

On the other hand, the unlocking mechanism portion 22 formed in the outer member 4 has a rotating shaft 31 which is held perpendicularly to a surface of the sliding door 1 formed at a right angle to the window glass surface P of the sliding door 1.

Therefore, the rotating shaft 31 is installed parallel to and horizontal to the window glass surface P, and the lever 32 is fixed to one end of the rotating shaft 31 located inside the outer member 4 so as not to rotate. .

The lever 32 is configured separately from the rotation shaft 31, and the lever 32
