Abstract

본 발명은 비틀림 코일 스프링을 가지는 댐퍼장치에 관한 것으로서 비틀림 코일 스프링의 예비 권취를 용이하게 하는 것을 그 목적으로 한다. 그 구성은, 기기본체에 부하되는 케이싱(2)의 원통형상부(7) 내에 동축적으로 댐퍼축(4)을 끼우고, 댐퍼축(4)의 원통형상부(16)내에 케이싱(2)과 댐퍼축(4)을 상대적으로 회동방향으로 탄지하기 위한 비틀림 코일 스프링(3)을 동축적으로 수용하고, 원통형상부(7)내에 오일을 봉입하고, 원통형상부(7)의 트인구멍부에 캡(7)을 부착한다. 댐퍼축(4)과 캡(6)에, 서로 대향하는 걸어맞춤 볼록부(23, 25)를 형성한다. 댐퍼축(4)을 회전시키면 양 걸어맞춤 볼록부(23, 25)가 서로 타고 넘어서 비틀림 코일 스프링(3)을 예비 권취한 상태로 지지할 수 있기 때문에, 케이싱을 기기본체에 부착한 상태에서 댐퍼장치에 덮개를 부착하기 전에 비틀림 코일 스프링을 예비권취하여 둘 수 있음으로 댐퍼장치의 조립성을 향상시킬 수 있다.The present invention relates to a damper device having a torsion coil spring, and its object is to facilitate preliminary winding of the torsion coil spring. The configuration is such that the damper shaft 4 is coaxially fitted in the cylindrical portion 7 of the casing 2 loaded on the device body, and the casing 2 and the damper in the cylindrical portion 16 of the damper shaft 4. A torsionally coiled spring 3 for holding the shaft 4 in a relatively rotational direction is coaxially accommodated, oil is enclosed in the cylindrical portion 7, and a cap 7 is formed in the open hole of the cylindrical portion 7. Attach). In the damper shaft 4 and the cap 6, engaging projections 23 and 25 which face each other are formed. When the damper shaft 4 is rotated, both of the engagement protrusions 23 and 25 can ride over each other to support the torsion coil spring 3 in a pre-wound state, so that the damper is attached to the machine body. The torsion coil spring can be pre-wound before the cover is attached to the device to improve the assembly of the damper device.
