The cutout 121 may be formed in a shape and size corresponding to the insertion portion 152 so that the insertion portion 152 can be inserted. For example, the cutout 121 may be formed in a square shape along the outer circumferential surface of the case 12. The position where the cutout 121 is formed may be determined according to the length of the torsion spring 11. For example, the cutout 121 may be formed near the center of the cargo sprint housing.

1 and 5, the cover 13 may be connected to one side and/or the other side of the case 12. The cover 13 may be connected to both sides of the case 12 to support the case 12. The other side of the spring may be connected to the cover 13 connected to one side of the case 12.

The cover 13 may include a cover body 131, a cover extension 132, a cover clasp 133, and a cover clasp head 134.

The cover body 131 may mean a body of the cover 13. The cover body 131 may be connected to one side of the case 12. The cover extension 132 may extend from the cover body 131 to the inside of the case 12. The cover extension 132 may extend along the length direction of the case 12. In a state in which the cover body 131 and the case 12 are coupled, the cover extension 132 may be located inside the case 12. The cover clasp 133 may protrude perpendicularly to the length direction of the cover extension 132 from the cover extension 132. That is, the protruding direction of the cover clasp 133 may be perpendicular to the longitudinal direction of the cover extension 132. The cover clasp head portion 134 may be formed at an end of the cover clasp portion 133 to have a larger radius than the cover clasp portion 133. The coupling ring 111b formed on the other side of the spring 11 may be connected to the cover clasp 133.

The protrusion 142 may protrude outward from the outer peripheral surface of the body part 141. At least one protrusion 142 may be formed. For example, three protrusions 142 may be formed and may be disposed at an isometric angle to each other. An insertion space may be formed between two adjacent protrusions 142. The insertion portion 152 of the clip 15 may be inserted into the insertion space formed between the adjacent two protrusions 142.

The direction in which the protrusion part 142 protrudes may be eccentric from the center of the body part 141. That is, based on the cross-sectional view of FIG. 4, an extension line in a direction in which the protrusion part 142 protrudes outward from the outer peripheral surface of the body part 141 may not pass through the center point of the body part 141. At the same time, the protrusion 142 may be formed such that one surface 142a passes through the center of the body portion 141. That is, the protrusion 142 may be formed such that the center of the body 141 is on the extension plane of the one surface 142a.

The head portion 143 may be formed on one side of the body portion 141. The head portion 143 may be formed with a radius corresponding to a length from the center of the body portion 141 to the end of the protrusion portion 142.

The clasp head portion 144c may be formed at an end of the clasp portion 144b with a larger radius than the clasp portion 144b. The coupling ring 111a formed on one side of the spring 11 may be connected to the clasp portion 144b. The clasp head portion 144c may prevent the coupling ring 111a from being separated from the clasp portion 144b.

2 to 4, the clip 15 may be coupled to the outer peripheral surface of the case 12. Clip 15 is coupled to the outer peripheral surface of the case 12, by limiting the position of the spring bar 14, the torsion spring 11 can be fixed. The clip 15 may be formed of a material or metal having elasticity. The clip 15 may include a ring portion 151 and an insertion portion 152.

The ring part 151 may have a ring shape with one side open so as to be coupled and detachable to the outer peripheral surface of the case 12. That is, the ring portion 151 may be coupled to or detached from the case 12 through an open side.

The insertion part 152 may protrude inward from the ring part 151. For example, the insertion part 152 may be formed by being bent inward in the ring part 151. The insertion part 152 may include a first bent part 152a and a second bent part 152b. The first bent portion 152a may be bent in a radial direction toward the center of the ring portion 151. The second bent portion 152b may be bent at a predetermined angle from the first bent portion 152a toward the circumference of the ring portion 151. Meanwhile, the insertion part according to an embodiment may be formed by extending the inner surface of the ring part in the inward direction in the above-described shape. The insertion portion 152 may be formed in a number corresponding to each other with the protrusion portion 142 and the cutout portion 121. For example, three insertion portions 152 may be formed, and may be disposed at an isometric angle to each other.

Hereinafter, a specific method of fixing the torsion spring 11 will be described with reference to FIGS. 2 to 4.

First, one side of the torsion spring 11 may be connected to the spring bar 14 and the other side may be connected to the cover 13. With the torsion spring 11 connected to the spring bar 14, the spring bar 14 can be pulled to a predetermined position within the case 12. For example, the spring bar 14 may be pulled to a position corresponding to the position where the cutout 121 is formed. In this state, the clip 15 may be coupled to the case 12 so that the insertion portion 152 of the clip 15 is inserted into the cutout portion 121. When assembled in this way, the insertion portion 152 can be inserted into a space between two protrusions 142 adjacent to each other. Then, the torsion spring 11 can be wound and positioned at a constant rotational speed. In this state, based on FIG. 4, even if the torsion spring 11 is wound (clockwise) or released (counterclockwise), the protrusion 142 and the insertion part 152 are in contact with each other and the spring bar 14 Since the position of the torsion spring 11 is limited, the position of the torsion spring 11 can be fixed. That is, in a state in which the clip 15 is coupled to the case 12, the protrusion 142 may contact the insertion part 152 to support the rotational force of the torsion spring 11. Specifically, one surface 142a of the protrusion 142 and the first bent portion 152a of the insertion portion 152 contact each other to support the rotational force of the torsion spring 11. Since one surface 142a of the protrusion 142 and the first bent portion 152a of the insertion portion 152 are located on a plane passing through the center of the body portion 141, the rotational force of the torsion spring 11 is easily I can support it. In addition, since the position of the head portion 143 of the spring bar 14 in the longitudinal direction is limited by the insertion portion 152, the position of the torsion spring 11 in the longitudinal direction may also be fixed. According to the above-described structure, since it is not necessary to use a screen bar, it is possible to reduce the number of parts and reduce the cost compared to the prior art. In addition, since the spring is fixed by a simple method of fastening the clip, the fixing structure is simplified and the assembling property is improved, and the ease of A/S can also be improved.
