SCREW ENGAGING TYPE DAMPER

摘要

The present invention relates to a screw coupled type-vibration damper, having a damper lower part manufactured to be separable and replaceable to improve the quality of coupling between components and damping force and having compatibility and generality to correspond to various kinds of components. According to the present invention, the screw-coupled vibration damper damping vibration comprises: a damper upper part (10), a damper lower part (20), a first cavity part (12), a second cavity part (22), a groove (11) and a spiral (12). The damper upper part (10) is formed in an axial direction. The damper lower part (20) is extended from a lower end of the damper upper part (10) in the axial direction. The first cavity part (12) is a space formed in the interior of the damper upper part (10) to damper vibration. The second cavity part (22) is connected to the first cavity part (12) to be formed in the interior of the damper lower part (20). The groove (11) is formed along a surface of the damper upper part (10) in a circumferential direction. The spiral (21) protrudes from a surface of the damper lower part (20).
