The projection 64 formed on the second return member fixing plate 63 is coupled to the opening 68 formed on the silicon return member 29. When the silicon return member 29 is coupled to the second return member fixing plate 63, the silicon return member 29 may be elongated and coupled in advance. Since the silicone return member 29 is pre-expanded and coupled to the second return member fixing plate 63, when the user releases the sliding force of the slide plate 24, the slide plate 24 is more accurate and faster than the original. Go back to the location. The second return member fixing plate 63 may be omitted intentionally or in accordance with the implementation environment of those skilled in the art.

The fixing guide 65 and the movement guide 66 are coupled to the PCB 32. Since the movement guide 66 is movable in the range of the fixing guide 65, when the user slides the slide plate 24, an input error is prevented by preventing the rotation and separation that may occur inadvertently.

A control unit (not shown) or a sliding detection sensor (not shown) is coupled to the PCB 32. The features of the PCB 32, the features of the controller (not shown), the features of the sliding sensor (not shown), and the method of coupling the controller (not shown) or the sliding sensors (not shown) to the PCB 32 may include a second method. As described in the embodiment, a detailed description thereof will be omitted for convenience.

The slide case 21 is coupled to the PCB 32 through the second coupling means 67. The coupling means 23 and the second coupling means 67 formed on the slide case 21 are coupled so that the PCB 32 is positioned therebetween. Since the coupling means 23 and the PCB 32 formed on the slide case 21 are coupled through the second coupling means 67, the slide part 90 is formed. The second coupling means 67 may use any coupling means capable of coupling the PCB 32 and the coupling means 23 formed on the slide case 21 such as screws, bolts, nuts, fusions, interference fits, and the like. .
