Abstract
A synchronous transmission pivot shaft device has a simplified structure and less assembled components and reduces assembling tolerance/motional space. The synchronous transmission pivot shaft device includes an assembly of a main body, a first operation board and a second operation board disposed on the main body. The first operation board has an obliquely extending arm section. The second operation board has an obliquely extending arm section. The arm sections of the first and second operation boards are respectively received in a first oblique rail and a second oblique rail of the main body. When a user operates the first operation board or the second operation board to move, the first operation board or the arm section thereof and the second operation board or the arm section thereof respectively synchronously move along the first and second oblique rails to achieve opening/closing effect.
