PROBLEM TO BE SOLVED: To prevent the theft of an electric apparatus. SOLUTION: A plug storage chamber 6 for inserting AC plug 5 is provided on the side surface of the cover 3 of an electric apparatus (for example, air compressor) and a lock pin 11 for engaging with the hole of blade 5a of the AC plug inserted in the plug storage chamber 6 is provided. The lock pin 11 is connected to a slide plate 10 and the lock/unlock of the AC plug 5 is carried out by sliding the slide plate 10. When the AC plug 5 is locked by the lock pin 11 and a padlock L is applied between the slide plate 10 and the bracket 12 of the cover 3, the AC plug 5 is fixed in an unremovable state. When an electric power cord 4 is hung around the column of a construction spot and the AC plug 5 is fixed in the plug storage chamber 6 and locked, the air compressor can not be brought out unless the power cord 4 is cut off.
