1. A hinge comprising:
a base frame unit including a base seat which is elongated in a front-rear direction, and two interfering plates, said base seat having an upper plate surface, two rotating recesses recessed from said upper plate surface and spaced apart from each other in the front-rear direction, and a transmitting recess recessed from said upper plate surface and interposed between and in communication with said rotating recesses, said interfering plates being disposed in said rotating recesses, respectively; and
a rotating unit including two rotating members which are respectively and rotatably disposed in said rotating recesses, and a bevel gear member which is disposed in said transmitting recess, each of said rotating members frictionally interfering with a respective one of said interfering plates, and having a bevel gear portion which meshes with said bevel gear member such that, a torque generated as a result of rotation of one of said rotating members relative to said base seat is transmitted through said bevel gear member to rotate the other one of said rotating members relative to said base seat so as to make synchronous rotation of said rotating members in opposite directions.
