14. A sliding opening and closing device, comprising:
a main plate;
a slide plate slidably coupled to the main plate;
an elastic part supported by the main plate, the elastic part generating an elasticity power;
a power transformation member for receiving the elasticity power of the elastic part, such that on a particular position in the moving path of the slide plate:
the power transformation member applies the elasticity power to the slide plate in the direction to be closed when the slide plate is in the closing position, and
the power transformation member applies the elasticity power to the slide plate in the direction to be opened when the slide plate is in the opening position;
wherein said power transformation member comprises a first block defining a first pivot hole, which is connected to be rotated around a first rotation pivot projecting from said slide plate;
At least one shaft part fixed to said first block; and
A second block defining a penetrating hole in which the shaft part is slidably engaged, and a second pivot hole to which is rotatably coupled a boss formed on the main plate.
