이때, 확장부(21)의 스크류부(23)가 홀더(11) 내면에 혈성된 나선홈(11b)에 인입되고, 스크류부(23)가 나선홈(11b)에 의해 가이드되어 이동하므로 절개부(11a) 내부로 이동되는 확장부(21)의 동작이 안정적으로 이루어지게 된다.At this time, the screw part 23 of the expansion part 21 is drawn into the spiral groove 11b formed on the inner surface of the holder 11, and the screw part 23 is guided by the spiral groove 11b to move, so the cutout part (11a) The operation of the expansion part 21 that is moved to the inside is made stably.

나아가, 본 실시예는 스크류부(23)가 나선홈(11b)에 인입되어 이를 따라 이동하므로 확장부(21)가 절개부(11a) 내부로 인입하는 과정에서 자유회전하게 되는데, 확장부(21)의 회전속도에 의해 도어(D)가 차량 실내측으로 이동되는 시간을 지연시키고, 외부 충격을 분산하여 충격 감쇄 효과를 발생시킨다.Furthermore, in this embodiment, since the screw part 23 is drawn into the spiral groove 11b and moves along it, the expanded part 21 is free to rotate in the process of being drawn into the cutout 11a, and the expanded part 21 ) delays the time the door D moves to the inside of the vehicle by the rotational speed, and distributes external shocks to generate an impact damping effect.

뿐만 아니라 스크류부(23)가 나선홈(11b)을 따라 이동하는 경우 도6에서 보는 바와 같이 스크류부(23) 표면에 형성된 다수의 돌기(23a)들이 나선홈(11b)이 형성된 홀더(11)의 내면에 마찰되어 충격을 보다 감쇄시킬 수 있다.In addition, when the screw portion 23 moves along the spiral groove 11b, as shown in FIG. 6 , a plurality of projections 23a formed on the surface of the screw portion 23 are the holder 11 in which the spiral groove 11b is formed. The impact can be further attenuated by friction on the inner surface of the

이때, 나선홈(11b)이 형성된 홀더(11)의 내면은 거칠기가 거칠게 형성되어 돌기(23a)와의 마찰이 보다 용이하게 이루어질 수 있도록 하는 것이 바람직하다.At this time, it is preferable that the inner surface of the holder 11 in which the spiral groove 11b is formed is roughened so that friction with the protrusion 23a can be made more easily.

그리고, 확장부(21)는 차량의 바디 프레임(B) 방향으로 갈수록 그 직경이 넓어지기 때문에 절개부(11a)에 삽입될수록 홀더(11)의 일단부를 내측에서 외측방향으로 가압하게 되며, 이에 홀더(11)의 일단부는 도7과 같이 외측으로 확장되어 지지홈이 형성된 차량의 바디 프레임(B) 내측에 고정지지된다.And, since the diameter of the extension 21 increases in the direction of the body frame B of the vehicle, as it is inserted into the cutout 11a, one end of the holder 11 is pressed from the inside to the outside, and thus the holder One end of (11) is extended to the outside as shown in FIG. 7 and is fixedly supported inside the body frame (B) of the vehicle in which the support groove is formed.

위와 같이 본 실시예는 스크류부(23) 및 나선홈(11b)에 의해 확장부(21)가 자유회전하면서 강성블럭(10)에 삽입되어 충격분산, 감쇄 효과를 얻을 수 있을 뿐 아니라 홀더(11)의 일단부가 차량 바디 프레임(B)의 내벽에 지지되어 도어(D)의 밀림을 매우 효율적으로 방지할 수 있다.As described above, in this embodiment, the expansion part 21 is freely rotated by the screw part 23 and the spiral groove 11b and is inserted into the rigid block 10 to obtain impact dispersion and damping effect as well as the holder 11 ) one end is supported on the inner wall of the vehicle body frame (B) to very effectively prevent the door (D) from being pushed.
