The present invention relates to a torque applying module which applies torque by being installed in first and second objects relatively rotating. The torque applying module includes: a cylinder fixed to one among the first and second objects, wherein one side is open; a spring installed in the cylinder; a slider elastically supported on the spring and connected to the inside of the cylinder by sliding in the longitudinal direction while rotation thereof is inhibited, wherein a first guide unit is formed at an end to be inclined in the longitudinal direction; a rotation body having a second guide unit formed to be inclined and engaged with the first guide unit to press the spring by moving the slider when relatively rotated with the slider, wherein the rotation body relatively rotates with the slider in opposite directions, when the spring is restored, and is fixed to the other one among the first and second objects; and a separation prevention unit installed in the cylinder to suppress the separation of the rotation body. According to the present invention, the torque applying module can improve reliability on a torque applying motion and has excellent durability. The torque applying module also has excellent assembly performance. So, the torque applying module can be manufactured at reduced costs and is easy to manufacture. |
