PROBLEM TO BE SOLVED: To provide a compact and electrically safe AC/DC plug by housing an AC plug blade within a DC plug having a cigarette plug structure. SOLUTION: When the AC plug blade 13 of this adapter is laid from housed state to used state, a lid body 4 is first opened. According to the opening, the base end part of the lid body 4 makes contact with the projection 13A of a plug blade 13 and pushes up the plug blade 13. Since the plug blade 13 is rotated 90 deg. and fixed in interlocking, when the lid body 4 is perfectly rotated counterclockwise 180 deg., it is inserted to the plug socket of a commercial power source, whereby AC power can be supplied. Since the plug blade 13 is separated from bent parts 8A, 11A, a (+)-electrode 6, a (-)-electrode 7 are separated from a pair of plug blades 13. Thus, even in the working state where the plug 13 is pulled out, it is in the state cut from the electrodes 6, 7, and safe even when a hand touches it. |
