By doing so, it is configured to be stretched between the optical housing portion 10 of the lower case 3 and the leg portion 38.

Next, the operation of such a mobile terminal will be described.
First, a case where the side trigger keys 11 are attached to both sides of the lower case 3 will be described. In this case, the elastic member 23 attached to the button portion 22 inserted into the button insertion hole 26 of the lower case 3 in the first step is arranged in the lower case 3 together with the button portion 22.

  That is, in the first step, the plurality of pressing portions 22b of the button portion 22 are made to bite into the bulging portion 23a of the elastic member 23, and the elastic member 23 is attached to the peripheral portion of the button portion 22 by adhesion. In this state, the button portion 22 is inserted into the button insertion hole 26 of the lower case 3 from the inside of the lower case 3, and the peripheral portion of the elastic member 23 is arranged on the inner surface of the lower case 3.

  Then, in the second step, the contact member 24 is guided by the pair of guide portions 25 provided on the inner surface of the lower case 3 located on both sides of the elastic member 23 so as to gradually approach the elastic member 23 and overlap each other. . That is, in the second step, the guide rails 31 of the pair of guide portions 25 guide the pair of slide portions 32 of the contact member 24 in the vertical direction, so that the contact main body portion 27 tilted with respect to the guide rail 31. The electrode surface is opposed to this and overlapped with the facing surface of the elastic member 23 inclined with respect to the guide rail 31.

  At this time, the facing surface of the elastic member 23 facing the electrode surface of the contact body 27 is inclined with respect to the guide rail 31 at a draft of about 4 °, and similarly, the electrode surface of the contact body 27 is also tilted. It is inclined. Therefore, when the guide rail 31 guides the slide portion 32 of the contact member 24 at the start of guiding, the electrode surface of the contact main body portion 27 is changed as shown in the principle diagrams of FIGS. 10A and 10D. It is arranged with a clearance a between the facing surface of the elastic member 23 and the electrode surface of the contact body 27 in a state of being displaced in the surface direction facing the facing surface of the elastic member 23.

  In this state, when the guide rail 31 guides and slides the slide portion 32, the contact main body portion 27 is elastic member during the slide, as shown in the principle diagrams of FIGS. 10B and 10D. 23, the clearance a between the facing surface of the elastic member 23 and the electrode surface of the contact main body portion 27 gradually narrows.

  Then, when the guide rail 31 slides by guiding the slide portion 32 and the contact member 24 reaches the bottom portion of the lower case 3, at the end of the slide, the principle diagrams of FIGS. 10C and 10D are shown. As described above, the facing surface of the elastic member 23 and the electrode surface of the contact main body portion 27 face each other and are pressed against each other in a state of being overlapped with each other to be pressed against each other.

  Accordingly, when the contact member 24 is superposed on the elastic member 23, the contact member 24 and the elastic member 23 can be prevented from rubbing against each other and being damaged. Therefore, the contact electrode 27a of the contact member 24 and the movable contact 23b of the elastic member 23 do not rub against each other, and the contact electrode 27a of the contact member 24 is damaged or the movable contact 23b of the elastic member 23 is damaged. Since it does not occur, contact failure will not occur.
