An opening-closing device of an electronic device with a reduced number of components, simplified configuration, self-fixing function and low cost is disclosed. A second housing is connected to the opening-closing device and thus is capable of rotating with respect to a first housing. The opening-closing device includes an assembling element, a supporting element and a means of rotating control. The assembling element is disposed on the first housing. The supporting element supports the second housing, which is rotatable with respect to the assembling element by a hinge shaft. The means of rotating control controls the rotation of the supporting element and includes a means of gum and a means of elasticity. The means of gum is disposed on one side of the hinge shaft and rotatable along with the supporting element. The means of elasticity is disposed on one side of the assembling element and connected to the means of gum. The means of elasticity is used to rotate the supporting element along with the means of gum at the same time. |
