PROBLEM TO BE SOLVED: To provide a portable terminal capable of preventing chattering noises generated by key members requiring no extra components while reducing the housing dimensions.SOLUTION: In a normal state (a state that a press part 301 in a side key 300 is not pressed from the outside), the side key 300 is disposed in a state that an anti-pull off part 305 is in contact with an anti-pull off plane 203 of a back case 200 due to an elastic force of protrusion 403 of a key packing 400, a hook 303 is in contact with a hook catch 104 of a front cover 100, and a projection 302 is separated from the key packing 400 (a state that no pressure is applied to a diaphragm switch). In the normal state, since the anti-pull off part 305 is in contact with the front cover 100 or the anti-pull off plane 203 of the back case 200, even when vibrations are generated on a side key housing by the vibrator (not shown) or the speaker (not shown) disposed in a main body, no chattering noise is generated. |
