Summary:To prevent deterioration of an attenuation function resulting from aggregation of powder.SOLUTION: A powder damper A comprises a case 10, a powder 27 stored in a working space 13 in the case 10, and a movable body 20 that moves back and forth while contacting the powder 27. The case 10 has an end wall surface 15 located on an extension line of a reciprocating path of the movable body 20. A cross-sectional area of an end space 17 facing the end wall surface 15 in the working space 13 is set to be larger than a cross-sectional area of a constant diameter space 16 other than the end space 17 in the working space 13.SELECTED DRAWING: Figure 1 【課題】粉粒体の凝集に起因する減衰機能の低下を防止する。【解決手段】粉粒体ダンパＡは、ケース１０と、ケース１０内の作動空間１３に収容された粉粒体２７と、粉粒体２７に接触した状態で往復移動する可動体２０と、を備え、ケース１０は、可動体２０の往復移動経路の延長線上に位置する端壁面１５を有し、作動空間１３のうち端壁面１５に臨む端部空間１７の断面積は、作動空間１３における端部空間１７以外の定径空間１６の断面積よりも大きくなるように設定されている。【選択図】図１
