Abstract: An apparatus for locking a battery pack in a portable communication terminal is provided to stabilize the locking and unlocking of the battery pack, thereby preventing the erroneous operation of the apparatus. A locking member(31) is mounted on a lower end portion of a bottom surface of a main body(10) while an upper surface of the locking member is exposed to the outside. The locking member is reciprocated in a longitudinal direction of the main body according to whether the locking member is pressed. First and second moving members(32,33) are in parallel with both right and left of the locking member. The first and second moving members are moved according to the movement of the locking member, thereby maintaining or canceling the locking state of a battery pack. A first elastic body(34) is installed between the main body and the locking member to provide a force for moving the locking member away from the moving members. Second elastic bodies(35) are respectively installed between the main body and one of the moving members and between the main body and the other of the moving members. A guide part(103) keeps the parallel movement of the locking member and the first and second moving members. A first catching unit is installed on a bottom surface of the battery pack. The first catching unit cancels the locking state of the battery pack according to the movement of the locking member.
