또한, 본체부(210)의 외측 원주면에는 고정 스크류(130)의 체결시 고정 스크류(130)의 헤드부(132)와 어버트먼트(120)의 안착부(122)와 밀착을 이루도록 구성되는 탄성부(220)가 형성된다. The outer circumferential surface of the main body 210 is configured to closely contact the head portion 132 of the fixing screw 130 and the seating portion 122 of the abutment 120 when the fixing screw 130 is fastened The elastic portion 220 is formed.
즉, 본 발명은 본체부(210)가 풀림방지 부재(200)의 내주면을 이루도록 구성되는 것이고, 탄성부(220)가 풀림방지 부재(200)의 외주면을 이루도록 구성되는 것으로, 그 대략적인 형상이 와셔의 형상으로 형성되는 것이다. That is, according to the present invention, the main body 210 is configured to form the inner peripheral surface of the release preventing member 200, and the elastic portion 220 is configured to form the outer peripheral surface of the release preventing member 200, And is formed in the shape of a washer.
탄성부(220)는 본체부(210)와 일체로 형성되며, 소정의 각도를 가지도록 경사지게 형성되는 것으로, 본체부(210)의 외측 선단부로부터 일정 각도만큼 하향 절곡되게 형성되며, 소정의 탄성력을 가지는 것이다. The elastic part 220 is integrally formed with the main body part 210 and is inclined to have a predetermined angle. The elastic part 220 is formed to be bent downward at a predetermined angle from the outer end of the main body part 210, I have.
이러한 탄성부(220)는 고정 스크류(130)의 체결시 상기 고정 스크류(130)로부터 전달되는 체결 압력에 의해 본체부(210)와 동축선상에 위치하도록 펼쳐지면서 그 상부면 및 하부면이 각각 고정 스크류(130)의 헤드부(132)의 저면부와, 어버트먼트(120)에 형성된 안착부(122)에 각각 완전하게 밀착을 이루면서 어버트먼트(120)와 픽스쳐(110) 사이에 유격이 발생한다 하더라도 상기 고정 스크류(110)가 풀리는 것을 방지하는 역할을 한다. The elastic part 220 is stretched so as to be coaxial with the main body 210 by the tightening pressure transmitted from the fixing screw 130 when the fixing screw 130 is fastened, A gap is formed between the abutment 120 and the fixture 110 so as to completely close the bottom portion of the head portion 132 of the screw 130 and the seating portion 122 formed in the abutment 120, Thereby preventing the fixing screw 110 from being loosened.
또한, 본 발명의 탄성부(220)는 도 4에 도시된 바와 같이, 본체부(210)의 일측부 및 타측부에 대한 탄성부(220)의 경사각(a)이 동일한 각도로 이루어질 수 있으나, 이에 한정하는 것은 아니다. 4, the inclined angle a of the elastic portion 220 with respect to the one side portion and the other side portion of the body portion 210 may be the same, But is not limited thereto.
이에, 고정 스크류(130)의 체결에 의해 발생하는 체결 압력으로 인해 상기 경사각(a) 만큼 하향 경사지게 형성되는 탄성부(220)가 펼쳐지면서 상부면이 헤드부(132)의 저면과 밀착을 이루게 되고, 이와 동시에 하부면이 어버트먼트(120)의 안착부(122)와 밀착을 이루면서 고정 스크류(130)와 어버트먼트(120) 간의 긴밀한 결합이 유지될 수 있도록 함에 따라 어버트먼트(120)와 픽스쳐(110)의 접하는 부분에 마모가 발생한다 하더라도 어버트먼트(120)의 싱크다운 방지 및 고정 스크류(130)의 풀림 현상을 방지할 수 있게 되는 것이다. As a result of the tightening pressure generated by the fastening of the fixing screw 130, the elastic part 220, which is inclined downward by the inclination angle a, is unfolded so that the upper surface is in close contact with the bottom surface of the head part 132 The lower surface of the abutment 120 is in close contact with the abutment portion 122 of the abutment 120 so that the abutment 120 can maintain the tight engagement between the abutment 120 and the abutment 120, Down of the abutment 120 and the loosening of the fixing screw 130 can be prevented even if abrasion occurs at the contact portion between the fixture 110 and the fixture 110. [

이때, 탄성부(220)의 일측부를 이루는 경사각(b1)은, 타측부를 이루는 경사각(b2)의 경사각도 보다 크게 형성될 수 있으며, 상기 경사각(b1)과 경사각(b2)의 크기는 고정 스크류(130)의 체결 방향에 따라 달라질 수 있다.The inclination angle b1 and the inclination angle b2 of the elastic portion 220 may be greater than the inclination angle of the inclination angle b2 forming the other side portion. (130).
이에, 고정 스크류(130)를 픽스쳐(110)에 체결할 때, 동일한 체결 압력으로 체결이 이루어지지 않고, 고정 스크류(130)의 어느 한 지점으로 편향되게 체결 압력이 가해진다 하더라도 고정 스크류(130)와 픽스쳐(110)가 동축선상에서 체결이 이루어지도록 안내할 수 있게 되는 것이다.
