摘要： A SIM card mounting structure of a mobile phone includes a SIM card receiving recess 5 provided in a rear surface portion of a front side casing of the mobile phone for fittingly receiving a SIM card 1 therein, a pressing portion 3 formed of an elastic material and having one end integrally formed with the rear surface portion of the front side casing and the other end positioned over the SIM card receiving recess to elastically press the SIM card 1 and electrode terminals 2 for connecting electrodes of the SIM card 1 to a battery. The electrode terminals 2 are formed of an elastic material and arranged on a bottom of the recess 5 in an opposing relation to electrodes of the SIM card 1. The one end of the pressing portion is formed integrally on an end portion of the SIM card receiving recess 5 in a longitudinal direction of the mobile phone such that the pressing portion functions as a longitudinal leaf spring. The pressing portion 3 has a notch 4 for setting elasticity of the pressing portion appropriately and facilitating a handling operation of a SIM card.

摘要： A structure for supporting an antenna is composed of an antenna-supporting member which is formed under a radiator and shaped into a cylinder, an antenna-inserting portion which includes the first cylindrical space for accommodating the antenna-supporting member, locking claws which are connected with a lower end of the antenna-supporting member and interlocked with a lower edge of an inner wall of the first cylindrical space, and a rubber bush which includes a through hole, through which the antenna-supporting member passes, and is inserted between the radiator and the antenna-supporting member. An upper part of the antenna-inserting portion includes the second cylindrical space, which is concentric with the first cylindrical space and has an internal diameter larger than that of the first cylindrical space, and a lower part of the rubber bush fits into the second cylindrical space.
