In addition, in this embodiment, the housing 11 and the handle 12 of the door locking handle 1 are respectively formed as vertically elongated rectangles, of course, this shape can be changed arbitrarily in terms of design. In addition, the operating rod 13 is formed integrally with the handle 12 , but it may be formed separately, and the operating rod 13 is attached to the shaft 121 at a predetermined angle with respect to the handle 12 . In addition, although the locking lever 14 adopts the above-mentioned shape, as long as it is pivotally supported by the shaft 140 perpendicular to the shaft 121 of the handle 12, one side rotating end rotates and engages with the working rod 13, and the other The shape of the structure in which the side rotating end rotates around and engages with the receiving portion 312 on the housing side is arbitrary. In addition, although the stopper 15 of the handle 12 adopts the above-mentioned form, it is not particularly limited to this form, as long as the handle 12 can be held in the depressed position, of course, it can also be changed to the one applied to the existing flat handle. other forms. In addition, a lock unit 154 for locking the stopper 15 is provided on the main body case 11 to lock the handle 12 in the depressed position, but it may be replaced with a lock provided in the handle 12 itself to lock in the depressed position. head unit. In addition, although the locking handle 1 for doors was exemplified as an outer handle, it is also applicable to the form attached to the inside of the housing 31 in the same way.

Moreover, in the above-mentioned embodiment, the multi-point locking locking device 2 adopts a special type of door locking handle 1, but the handle device adopted by the existing multi-point locking locking device can also be applied.
