Claims (3)
- ハンドル側チューブと車輪側チューブとで伸縮可能に形成されたフォーク本体内に配設のダンパがシリンダ体をハンドル側チューブに連結すると共にこのシリンダ体に出没可能に連繋するロッド体を車輪側チューブに連結する倒立型に設定されてなるフロントフォークにおいて、
ハンドル側チューブに連結されるダンパにおけるシリンダ体のボトム端部内にベースバルブ部が配設されると共にこのベースバルブ部の下流側にあってベースバルブ部に対向しながら加圧手段で背後から附勢されるフリーピストンを有する一方で、
このフリーピストンとベースバルブ部との間に配設されながらベースバルブ部に担持されてフリーピストンを後退方向に附勢することを可能にするサブバネを有してなることを特徴とするフロントフォーク。 - サブバネのバネ力がフォーク本体の最伸長時にフリーピストンを挟んで加圧手段のバネ力と釣り合う一方で、フォーク本体が最伸長状態から収縮作動を開始するときにフリーピストンの後退を促し、フォーク本体における収縮が所定量になるときに先端がフリーピストンから離座されてなる請求項1に記載のフロントフォーク。
- シリンダ体のボトム端部内に圧側減衰バルブを有すると共に、この圧側減衰バルブの下流側にフリーピストンが配設されて油室が画成され、この油室にサブバネが配設されてなる請求項1に記載のフロントフォーク。
