Abstract

A support device for supporting an upper body of an electronic apparatus is disclosed. The electronic apparatus further comprises a lower body, and the upper body pivotally rotates relative to the lower body. The support device comprises a rotating element disposed on the lower body and having a thread surface, a first gear disposed on the upper body, a second gear meshing with the first gear at one side and meshing with the thread surface of the rotating element at another side, a first resistant torque providing element disposed under the rotating element, and a second resistant torque providing element disposed under the first resistant torque providing element. The first resistant torque providing element and the second resistant torque providing element provide resistant torques in counter directions to gradually dissolve the weight load of the upper body during the opening or closing processes, so as to stably support the upper body of the electronic apparatus.
