Abstract
【解決手段】軸方向に連通するオリフィス(13)を備えたピストン(4)でシリンダ(3)を軸方向について2分割し、該ピストンがシリンダ内を軸方向に移動する際のオリフィスを通過する粘性流体の抵抗によって制動力を発生させるダンパにおいて、前記ピストンを、ピストンロッドと一体をなすインナ部材(4a)と、インナ部材の外周に軸方向移動可能に装着されたアウタ部材(4b)とからなるものとし、これらインナ・アウタ両部材を、粘性流体が流動し得る空隙(G)をおいて相互に遊嵌すると共に圧縮コイルばね(12)によって互いに離間する向きに弾発付勢し、アウタ部材内へのインナ部材の突入量が増大すると両者間の空隙が狭くなるものとする。

Claims (1)
- 粘性流体を封入したシリンダと、該シリンダ内を軸方向について2分割すると共に軸方向に連通するオリフィスを備えたピストンと、該ピストンに連結されたピストンロッドとを有し、前記ピストンロッドと共に前記ピストンが前記シリンダ内を軸方向に移動する際の前記オリフィスを通過する前記粘性流体の流動抵抗によって制動力を発生させるダンパであって、
前記ピストンは、前記ピストンロッドと一体をなすインナ部材と、該インナ部材の外周に軸方向移動可能に装着されたアウタ部材とからなり、これらインナ・アウタ両部材は、前記粘性流体が流動し得る空隙をおいて相互に遊嵌すると共に圧縮コイルばねによって互いに離間する向きに弾発付勢されており、前記空隙は、前記アウタ部材内への前記インナ部材の突入量が増大すると狭くなるようにされていることを特徴とするダンパ。
