Claims

[Scope of utility model registration request]

A hinge arm is pivotally supported on an inner wall of a trunk room so as to be vertically movable, a pivoting end of the hinge arm is extended toward an opening that opens the trunk room upward, and a trunk lid is attached to the pivoting end of the hinge arm, A torsion device for opening and closing a trunk lid, which is configured to cause the trunk lid to open and close the opening by vertical movement of the trunk lid accompanying the hinge arm, and is provided with a torsion bar for urging the hinge arm to rotate upward, The torsion bar is composed of a torsion bar body that extends along the rotation axis in the vicinity of the rotation axis of the hinge arm, and an arm portion that bends radially outward from the torsion bar body. The arm section is pressed against the hinge arm while applying a twist to the torsion bar main body so as to bias it in the upward rotation direction, and as the hinge arm rotates upward, the pressure contact position of the arm section with respect to this hinge arm changes to the same hinge arm as above. A torsion device for opening and closing a trunk lid, characterized in that the torsion device is arranged to be close to the rotation axis of the trunk lid.
