PURPOSE: A device for opening/shutting an earphone jack port of a mobile communication terminal is provided to open upper/lower stoppers with a force of inserting an earphone jack without a user opening/shutting the stoppers directly, and to shut the upper/lower stoppers by elastic restoring forces of elastic members, thereby preventing the stoppers from being transformed or damaged. CONSTITUTION: Upper/lower stoppers(102a,102b) open/shut a pierced hole(101) formed on a housing(100) of a mobile communication terminal in forward direction of an earphone jack port(106). Sloping portions(103a,103b) are formed such that a portion of a front end of an earphone jack(107) is inserted into outer sides of a lower end of the upper stopper(102a) and an upper end of the lower stopper(102b). An upper slide guide case portion(104a) and a lower slide guide case portion(104b) are inserted inside the housing(100) so that the upper stopper(102a) and the lower stopper(102b) slidingly move in vertical direction by being inserted. Elastic members(105a,105b) supply elastic forces to the upper and lower stoppers(102a,102b) in order to shut the pierced hole(101) by being inserted into the upper/lower slide guide case portions(104a,104b).
