The lock mechanism is attached to a plug main body 10 to be movable forward and backward in an inside-outside direction of the plug main body 10; and at an upper portion thereof a lock button 19 that is a button having an engaging portion 29 engaging with the lid body. The lock button 19 is composed of a button main body member 26 provided with the engaging portion 29; a spring 65 that energizes the engaging portion 29 of the main body member 26 of the button in a direction of engaging with the lid body; and a button assembling member 27 that is attached so as to cover a part of the outer peripheral surface of the main body member 26 of the button. The main body member 26 of the button is incorporated slidably by a lock rotating shaft nearly parallel to a lid hinge portion that pivotally supports the lid body 12. Integration of the button assembling member 27 with the main body member 26 of the button is maintained by the lock rotating shaft. |
