The present invention relates to a trunk lid opening angle-adjustable tension spring structure including a tension spring which has one side end assembled in a vehicle body and the other side end assembled in a trunk lid or a hinge bracket which extends from the trunk lid to the vehicle body, accumulates energy for a trunk link opening while stretching during trunk lid closing, and opens the trunk lid while contracting to an initial state during trunk lid unlocking; a first fixed bracket disposed to be fixed inside one side end of the tension spring, and has a female screw hole formed in a central portion to extend in a longitudinal direction of the tension spring; a control shaft disposed in the female screw hole to extend in the longitudinal direction of the tension spring through the first fixed bracket, has a male screw to screw couple with the female screw hole formed in an outer surface, and moves in the longitudinal direction of the tension spring during rotation; a second fixed bracket disposed to be fixed inside the other side end of the tension spring; and a stopper disposed on an inner side end of the control shaft to be positioned inside the tension spring and suppresses the second fixed bracket movement and tension spring contraction while in contact with the second fixed bracket moving due to a tension spring contraction, and a position where contact with the second fixed bracket starts being controlled while the stopper approaches or is moved apart from the second fixed bracket due to the movement of the control shaft. |
