제4도는 상기한 접동자(7)를 설치한 회전체(3)를 커버(2)에 수납시킨 조립상태의 일부파단의 측면도이고 동 도면으로서 명백하여진 바와같이 상기한 플랜지부(5d)의 하단측의 복수의 접동각부(5f)……가 절연기관(1)의 윗면에 직접탄접접하여 접동자 받침(5)(회전체 3)의 회동시의 안내기능을 하고 있음과 동시에 프랜지부(5d)가 전술한 바와같이 약간 부상한 상태에서 절연기판(1)에 대접하여 있으므로 접동자 받침(5)의 어깨부(5a)는 커버(2)의 상부저면에 압착되어 접동자 받침(5)는 커버(2)와 절연기판(1)과의 사이에서 항상 적당한 탄성을 부여한 상태로 유지되도록 되어있다.FIG. 4 is a side view of partly broken in the assembled state in which the rotating body 3 provided with the sliding member 7 is accommodated in the cover 2, and as shown in the drawing, the lower end of the flange portion 5d. A plurality of sliding angle portions 5f on the side; … Is in direct contact with the upper surface of the insulator 1, and functions as a guide during the rotation of the slide support 5 (rotator 3), and the flange portion 5d is slightly injured as described above. Since the shoulder base 5a of the sliding base 5 is pressed against the upper surface of the cover 2 because the upper surface of the sliding base 5 is welded to the insulating base 1, the sliding base 5 is connected to the cover 2 and the insulating substrate 1. It is supposed to be maintained in a state in which moderate elasticity is always provided between.
이상 기술한 바와 같이 본 고안에 의하면 접동자 받침(5)이 이 접동자 받침과 일체의 탄성을 가진 플랜지부(5d)에 의해 커버(2)와 절연기판(1)과의 사이에 적당한 탄성을 가지고 유지되므로 회전체(3)의 회전력(torque)을 별개의 스프링등의 회전력을 내는 수단없이, 간단, 용이하게 행하여 양호한 회전감촉을 가진 가변저항기를 값싸게 제공함 수 있고 플랜지부(5d)가 접동자 받침(5)의 주면에 있으므로 접동자 받침(5)의 회전도 안정한 실용상 현저한 효과를 가진다.As described above, according to the present invention, the slider support 5 is provided with an appropriate elasticity between the cover 2 and the insulating substrate 1 by the flange portion 5d which is integral with the slider support. Since it is held, the torque of the rotating body 3 can be provided simply and easily without a means for producing a torque such as a separate spring, so that a variable resistor having a good rotational feel can be provided at low cost, and the flange portion 5d is brought into contact. Since it is on the main surface of the movable base 5, the rotation of the sliding base 5 also has a remarkable practical effect.
그리고 도면에 나타낸 가변저항기는 본 고안의 1실시예로서 본 고안의 개량된 접동자 받침부는 각종의회전형 가변저항기에 응용할 수 있는 것은 물론이며 또 접동자 받침(5)내에 접동자(7)와 이것에 대응하는 저항체등이 위치하도록 플랜지부(5d)와 기판면과의 간격은 미소하므로 설치각부(2d)의 형성에 의해 커버(2)에 개구부를 설치하여도 그 방진(防塵)효과는 충분하다.In addition, the variable resistor shown in the drawings is an embodiment of the present invention, and the improved slide support of the present invention can be applied to various rotary variable resistors, as well as the slide 7 and the slide in the slide support 5. The distance between the flange portion 5d and the substrate surface is small so that a resistor or the like corresponding thereto is located, so that the dust-proof effect is sufficient even if an opening is provided in the cover 2 by forming the mounting angle portion 2d. .
