A torque testing device is for testing the torque of a hinge. The torque testing device includes a main board, two sidewalls respectively located at two sides of the main board, and a loading board rotatably mounted between the sidewalls. The loading board is for retaining the hinge. Additionally, a sensor is mounted on the loading board. a measuring element is mounted on the sensor, and a testing ring is mounted on the main board. The hinge is rotated to drive the loading board to rotate relative to the sidewalls so the measuring element move toward and presses the testing ring, thereby the testing ring applies torque to the measuring element and the sensor senses the torque applied to the measuring element, which is equal to the torque of the hinge being tested.
