Claims (4)
- シリンダー体及びピストン体を備え、少なくともこれらのいずれか一方の側を制動対象物に取り付けさせることにより、制動対象物の移動又は相対的な移動に制動力を作用させるダンパー装置であって、
前記ピストン体に向き合う前記シリンダー体の閉塞部の外側に、このシリンダー体の内外を連通させる流路を形成させる突出部と、
この流路に前記シリンダー体の外側から入れ込まれる軸部を備えた栓状体と、
この栓状体の付勢手段とを備えており、
前記シリンダー体の閉塞部から離れる向きの前記ピストン体の移動又は相対的な移動により生じる圧力変化によって前記付勢手段の付勢に抗して前記流路への栓状体の軸部の入り込み寸法が増加するようになっていると共に、
栓状体に、軸部の基部の側方にあって、この軸部の流路への入り込み寸法が最大となったときに突出部の突き出し端に当接してこの栓状体による流路の閉鎖を阻止する突部が形成されていることを特徴とするダンパー装置。 - シリンダー体の閉塞部の外側には、シリンダー体の内側に凸所を作る凹所が形成されており、この凹所内に突出部が備えられていることを特徴とする請求項1に記載のダンパー装置。
- ピストン体に、シリンダー体の内側に形成された凸所の納まる凹部が形成されていることを特徴とする請求項2に記載のダンパー装置。
- シリンダー体の閉塞部の外側には、この閉塞部の外縁よりこの閉塞部の中央側にあって突出部を囲繞する周回壁部が形成されており、この周回壁部の内側において移動可能に栓状体が支持されていることを特徴とする請求項1〜請求項3に記載のダンパー装置。
