ABSTRACT:
A folding portable wireless apparatus of the invention is provided with locking mechanisms provided on the both side faces of an upper and a lower case which are so configured as to be capable of opening and closing. The locking mechanisms have open levers which are provided on the both side faces of either the upper or the lower case and can be manually operated. To the both side faces of the other case are provided engaging portions which interlock with the open levers to lock the both cases, and locking impetus giving members for giving an impetus to the open levers are also provided in such a direction that the locked state established between the open levers and the engaging portions is maintained. In this structure, since the opening operation is carried out by both a thumb and an index fingers of a hand holding the portable wireless apparatus, the easy and rapid opening operation is possible no matter which hand may being holding the wireless apparatus.
