<P>PROBLEM TO BE SOLVED: To prevent a plug from being unable to be opened when only a button operating member is pressed even if an appearance surface of a button operating member is comparatively large, to increase the certainty of an opening action of the plug for improving visibility of a button portion to be pressed, and to easily and surely perform an opening operation of the plug for improving visibility and operability. <P>SOLUTION: A lock mechanism 17 is provided for keeping a plug 12 in a closed state. An engaging piece 35 is provided at the plug 12. A lock button 19 of the lock mechanism 17 includes a button body member 26 with an engaging portion 29, and a button operating member 27 attached to the button body member 26 and further has a spring 49 for biasing the lock button 19 in an engaging direction. The button operating member 27 is forcibly fitted not only to the spring 49 but also to the button body member 26. Therefore, even when only the button operating member 27 is pressed, the button body member 26 surely moves in conjunction with the button operating member 27 to open the plug 12 without fail. <P>COPYRIGHT: (C)2013,JPO&INPIT |
