JP-A-11-331332 [H04M1 / 02]

However, in the above-described slide type mobile phone, the two casings (3) and (4) are overlapped with the maximum overlap as shown in FIG. A large gap E exceeding, for example, 1 mm is formed between the end surface (30) of the operation side housing (3) and the end surface (40) of the display side housing (4) when sliding to the closed state where the areas overlap. There was a problem that occurred and looked bad.
The large gap E between the end faces (30) and (40) of the two casings (3) and (4) is caused by the guide grooves (31 that guide the slides of the two casings (3) and (4)). ) Extends until it reaches the end surface (30) of the operation side housing (3), but the slide portion (43) has a length that reaches the end surface (40) of the display side housing (4). The guide groove (31) and the slide part (43) are engaged with each other in the region near the end faces (30) and (40) when both the casings (3) and (4) are closed as shown in the figure. This is because the two casings (3) and (4) are separated from each other in the vicinity of the end faces (30) and (40) and are thus opened.

  If the slide part (43) of the display-side housing (4) is formed to a length that reaches the end surface (40), the clearance between the end surfaces (30) and (40) of both housings (3) and (4) is the design value. However, since the slide part (43) is formed from a separate low-resistance member to reduce sliding friction with the guide groove (31), the slide part (43) is lengthened. Forming causes an increase in weight and cost.
