PURPOSE: A slide track in a sliding-type mobile phone is provided to prevent an upper main body from being separated from a lower main body and to firmly maintain the connection state between the upper and lower main bodies by the flange parts of a fixed block when the upper main body slides upward and downward. CONSTITUTION: A slide track in a sliding-type mobile phone comprises a guide rail(40), a fixed block(50), steel balls(61-64), and elastic hooking parts(80,90). The fixed block(50) is firmly fixed to the upper side of a lower main body through two screws. Flange parts(51L,51R), installed at both sides of the fixed block(50), are inserted into the channels(41L,41R) of the guide rail(40) respectively. A pair of female screw holes(53) are provided at the central part of the fixed block(50). The screws are connected with the female screw holes(53) so that the fixed block(50) can be fixed to the lower main body. Accordingly, as the flange parts(51L,51R) of the fixed block(50), fixed to the lower main body, maintain a state connected to the inside of the channels(41L,41R) of the guide rail(40), an upper main body can slide upward and downward.
