즉, 모터(71)가 회전하게 되면 모터축(72)이 회전하게 되고 상기 모터축(72)과 함께 회전구(62)가 회전하게 되고 쉼표형상의 회전구(62)와 맞닿인 볼조절구(63)는 회전되는 회전구(62)의 위치에 따라 회전되는 회전각이 달라지는데 이는 상기 볼조절구(63)의 접면(66)과 접한 스프링(64)의 탄성에 의한 것이다.That is, when the motor 71 rotates, the motor shaft 72 is rotated, and the ball orb is contacted with the comma-shaped rotary ball 62 by rotating the rotary ball 62 together with the motor shaft 72. The rotation angle of 63 is changed depending on the position of the rotating ball 62 to be rotated due to the elasticity of the spring 64 in contact with the contact surface 66 of the ball adjusting device 63.

만일, 모터(71)의 회전으로 쉼표형 회전구(62)의 패인 곳에 볼조절구(63)가 닿이도록 회전구(62)가 회전하게 되면 볼조절구(63)는 스프링(64)의 탄성에 의해 볼조절구(63)의 고정공(67)을 축으로 회전하게 되어 쉼표형 회전구(62)의 패인 곳에 맞닿이게 되고, 볼조절구(63)의 회전으로 볼조절구(63)의 삽입홈(65) 또한 회전하게 되어 브라켓(61)의 이동홈(68)과 연결되지 못하고 볼조절구(63)가 이동홈(68)을 가로 막아 볼(54)이 이동할 수 없어 상기 조절체(51)의 요홈(53)에 계속 머무르게 되는 구조이다.If, when the rotary ball 62 is rotated so that the ball control knob 63 is in contact with the hole of the comma-shaped rotary ball 62 by the rotation of the motor 71, the ball control knob 63 is elastic of the spring 64 By rotating the fixing hole 67 of the ball adjusting device 63 to the shaft is brought into contact with the indentation of the comma-shaped rotary ball 62, by the rotation of the ball adjusting device (63) of the ball adjusting device (63) Insertion groove 65 is also rotated so that it is not connected to the moving groove 68 of the bracket 61, the ball control mechanism 63 blocks the moving groove 68, the ball 54 can not move the control body ( The structure continues to stay in the groove 53 of 51).

그러나 모터(71)의 회전으로 회전구(62)의 볼록한 부분에 볼조절구(63)가 닿으면 회전구(62)의 볼록한 부분에 의해 볼조절구(63)는 스프링(64)이 압축되면서 볼조절구(63)의 고정공(67)을 축의 중심으로 반대로 회전하게 되어 볼조절구(63)의 삽입홈(65)이 브라켓(61)의 이동홈(68)과 연결되어 볼(54)이 이동홈(68)을 통해 작동부(60)내로 이동하게 되는 구조이다However, when the ball control mechanism 63 is in contact with the convex portion of the rotary ball 62 by the rotation of the motor 71, the ball control mechanism 63 is compressed by the spring 64 by the convex portion of the rotary ball 62. The fixing hole (67) of the ball adjusting mechanism (63) is rotated oppositely to the center of the shaft so that the insertion groove (65) of the ball adjusting mechanism (63) is connected to the moving groove (68) of the bracket (61) and the ball (54). It is a structure to move into the operation unit 60 through the moving groove (68).

즉, 작동부(60)내의 회전구(62), 볼조절구(63)와 스프링(64)의 상호 작동은 힘의 정점에서 미소한 힘을 가함으로 인해 회전구(62)와 볼조절구(63)가 회전하여 도어를 해제하는 구조인 것 이다.That is, the interaction between the rotary ball 62, the ball control mechanism 63 and the spring 64 in the operating unit 60 is due to the application of a small force at the peak of the rotary ball 62 and the ball control mechanism ( 63) rotates to release the door.
