Description
(1)細長い金属片が外筒の内周側に拡がる弧状の断面を持つ金属片である。
(2)細長い金属片の長さ(L)に対する湾曲部の頂部の高さ(H)の比率(H/L)で表される湾曲率が0.001乃至0.05の範囲にある。
(3)外筒部材の外周面に、長さ方向に沿って互いに平行に並ぶ、少なくとも三列の互いに同一の直径を持つ円周に沿って環状に形成されている突起を備える。
(4)上記外筒部材の内周部の両端部に密着状態で、ただし、該両端部に接合固定されることなく、弾性部材から形成された環状外筒補強部材が装着されている。
また、本発明の直動軸受を用いることにより、直動軸受に挿入された軸体(ロッド)の安定な(即ち、「ぶれ」や「がたつき」の少ない)直動が実現する。
