To make proper damping force function according to a relative displacement.SOLUTION: Three-dimensional fabrics 31,32 are provided in one of a first member 10 and a second member 20 provided relatively movably so that a clearance C between itself and the other in a direction orthogonal to a movement direction partially varies along the movement direction. Therefore, by a relative position of the first member 10 and the second member 20, a compression amount of the three-dimensional fabrics 31,32 by compression members 51,52 is varied, and accordingly, sliding resistance force applied to both of them varies. Thus, by adjustment of the clearance C between the three-dimensional fabrics 31,32 and the first member 10 or the second member 20, damping force generated when the first member 10 and the second member 20 relatively move can be set to various characteristics.SELECTED DRAWING: Figure 1
【課題】相対変位量に応じた適切な減衰力を機能させる。【解決手段】相対的に移動可能に設けられた第1部材10及び第2部材20の一方に、それらの移動方向に直交する方向における他方とのクリアランスCが、移動方向に沿って部分的に変化するように立体布帛31,32を設けている。このため、第1部材10及び第2部材20の相対位置により、圧縮部材51,52による立体布帛31.32の圧縮量が変化し、それにより両者間に働く摺動抵抗力が変化する。よって、立体布帛31,32と第1部材10及び第2部材20のいずれかとの間のクリアランスCの調整により、第1部材10及び第2部材20が相対移動する際に生じる減衰力を種々の特性に設定できる。【選択図】 図1
