Patent ID: 8599073

Claim:
A mobile terminal device comprising: a stationary-side housing that includes a stationary-side front case to which an antenna is attached and a stationary-side rear case; a movable-side housing; and a coupling hinge unit that couples the movable-side housing to the stationary-side housing, wherein the antenna includes an antenna body, an antenna shaft arranged at rear end of the antenna body, and an antenna attaching member arranged on the antenna shaft, the stationary-side front case has a shaft through-hole at a predetermined position through which the antenna shaft is insertable into the stationary-side front case, a connection establishing unit arranged on a circuit board inside the stationary-side front case abuts against an inserted tip of the antenna shaft and establishes an electric connection therewith, and the antenna body is fixedly attached to a predetermined position on the stationary-side front case by using the antenna attaching member, and wherein the antenna attaching member arranged on the antenna shaft has a screw through-hole through which a screw is insertable, the stationary-side front case has a screw hole at the predetermined position on the stationary-side front case in which a threaded portion of the screw is fixable, and a direction in which the antenna is inserted through the through-hole created on the stationary-side front case going in the same direction in which the screw is inserted through the screw through-hole created on the stationary-side front case, via a through-hole created on a flange, and wherein the connection establishing unit includes a pair of connection plates that open toward the shaft through-hole and form a substantial V shape while the antenna shaft abuts the pair of connection plates, the pair of connection plates close before the antenna shaft fits into the connection establishing unit, and the flange is arranged at a joint between the rear end of the antenna body and the antenna shaft and has a screw through-hole through which a screw is inserted.
