Abstract
An electronic device of the present application includes a case (1), a stem-shaped leg (3), and a leg fixing part (4). The leg fixing part (4) is provided on one face of the case (1) and includes a case thread ridge portion (4a) that is formed on an inside face of a hole, into which the leg (3) is inserted, and that is divided into isolated thread ridge portions. A peripheral face of a stem portion of the leg (3) has a first screw structure portion (3a), which is engaged with the case thread ridge portion (4a), and a second screw structure portion (3b) which is engaged with the case thread ridge portion (4a) before being engaged with the first screw structure portion (3a). The second screw structure portion (3b) has a guide portion (5a) and an idle turn inducing portion (5b). The guide portion (5a) guides the case thread ridge portion (4a) to the second screw structure portion (3b) when the leg (3) is inserted into the hole while being turned in a direction in which the leg (3) enters the case (1). The idle turn inducing portion (5b) causes the second screw structure portion (3b) to turn idly with respect to the case thread ridge portion (4a) when the leg (3) is turned in a directi…
