A coupled structure capable of keeping the coupled state between coupled members without degrading the appearance, and an electronic device including such a coupled structure are disclosed. A coupled structure includes a keyboard unit coupled with a main body chassis. The coupled structure includes a hook mechanism which engages the keyboard unit with the main body chassis when the keyboard unit moves in one direction relative to the main body chassis, a locking part formed at the main body chassis, and an elastic part formed at the keyboard unit, and the elastic part biases the keyboard unit engaged with main body chassis in the one direction relative to the main body chassis when the locking part locks the elastic part.

A multi-functional switch device includes: an integral panel in which four button parts are formed on the upper surface thereof, and a hook hanger including a hook hole formed at and protruding from the bottom of each button part; and a case including a stopper disposed at an upper portion of the case, and a hook protruding upward at a position corresponding to each hook hanger, the case connected to the panel. The stopper is arranged so that each button part is operated in a seesaw manner. Each hook and the hook hole are coupled to form a set gap, so that when one button part is pushed, a stroke of the corresponding button part is possible and operation of the other button parts is restricted.
