MOBILE RADIO TERMINAL DEVICE

PROBLEM TO BE SOLVED: To provide a mobile radio terminal device in which an interface cover can be easily attached to the opening of a casing from which an interface socket is exposed, and the interface cover can be prevented from coming off so easily after being attached. SOLUTION: In this mobile radio terminal device, a tongue piece 31 is projected from the end of a cover 30 on an interface cover 3 for covering the opening 4 formed at a casing 1, and an insertion path 40 through which the tongue piece 31 is inserted in the near position of the opening 4 is recessed and provided on the casing 1. Engaging holes 33 are formed in the tongue piece 31, and engaging pins 53 for engaging with the holes 33 to apply locking to the tongue piece 31 are projected midway along the path 40. Slope surfaces 54 for elastically deforming the tongue piece 31 so that the tongue piece 31 has a posture to allow the pins 53 can fit into the holes 33 are formed on the pins 53, respectively.
