<p>PROBLEM TO BE SOLVED: To provide a locking device for further hardly illegally unlocking an opening-closing door.SOLUTION: Respective extension pieces 12 are displaced in the opposite direction, and since a projection 14 of the respective extension pieces 12 is locked by contacting with a different area on the periphery of a fitting object part 120, force for opening the opening-closing door is dispersed to a plurality of areas at least in the fitting object part 120 or its periphery. Thus, in the embodiment, even if large force is added in the direction for opening the opening-closing door, the periphery of the fitting object part 120 is hardly damaged and broken as compared with a constitution for locking by sandwiching one member, and thus, final illegal unlocking of the opening-closing door can be effectively prevented.</p> |
