PROBLEM TO BE SOLVED: To provide a joint unit capable of absorbing vibration from a vibrating member and restricting a transmission of vibration to a shield member.SOLUTION: A joint 1 comprises: the first and second surfaces 20a, 30a oppositely arranged while a spacing having a shield 100 to be presentable therein; a biasing member 4 having a through-pass hole with a predetermined wire member being wound in an eddy form around the through-pass hole while its curvature factor being continuously changed and formed to be expandable or shrinkable; a holding part inserted into a hole and the through-pass hole formed at the shield 100 to hold a distance between the first surface and the second surface at a specified spacing. Biasing members 4a, 4b are arranged between the first surface 20a and the shield 100, and the first biasing member 4a is arranged between the first surface 20a and the shield 100 with a side having a low curvature in an expanding or retracting direction being arranged to be adjacent to the shield 100 and the second biasing member 4b is arranged between the second surface 30a and the shield 100 with a side having a low curvature in an expanding or retracting direction being arranged to be adjacent to the shield.SELECTED DRAWING: Figure 6 |
