A fixation method of a hinge point of a tailgate for an automobile adapted to improve a difficulty of fixing a hinge point due to a difference between a central roof panel and a hinge point of an outer block when a tailgate is mounted. The method of a hinge point of a tailgate for an automobile enables fixation within a short period of time and to preclude interference from a tailgate parting line and a roof panel parting line. The method comprises the steps of: drawing line segments G1 and G2 each detached at a predetermined distance from a central parting line P1 of the roof panel and fixing a circle C1 having the same curvature as the curvature R of the central parting line P1 so as to define G1 as a tangent; fixing the circle C1 to seek a cross point I1 with the line G2 and fixing a straight line segment L1 connecting the cross point I1 with a parting line P2 of the tailgate; fixing a circle C2 designating the straight line segment L1 as a diameter; and fixing a straight line segment L2 dividing and orthogonally crossing the circle C2 and the straight line segment L1 to fix a cross point I2 with the circle C2 at the tailgate side and to fix the cross point I2 as a hinge point.
