ROLLING BEARING DEVICE, BEARING STRUCTURE, SEISMICALLY ISOLATED STRUCTURE, AND VIBRATION CONTROL STRUCTURE
PROBLEM TO BE SOLVED: To increase durability by suppressing deformation and displacement.SOLUTION: A rolling bearing device includes: a pair of upper and lower plate members that are arranged in the state of facing each other; a cylindrical rolling element that bears a vertical load by coming into contact with the pair of upper and lower plate members and that rolls depending on relative displacement of the pair of upper and lower plate members in a predetermined direction; and a cage that rollably holds the rolling element between the pair of upper and lower plate members. The cage has a pinion that rotates on a rotational axis parallel to an axis of the rolling element. The pair of upper and lower plate members have surfaces on the opposed sides provided with racks for being engaged with the pinion, respectively.
【課題】変形や位置ずれを抑制し、耐久性の向上を図る。【解決手段】対向して配置された上下一対の板部材と、上下一対の板部材と接触して鉛直荷重を支持する円柱型の転動体であって、上下一対の板部材の所定方向への相対変位に応じて転動する転動体と、上下一対の板部材の間で転動体を転動可能に保持する保持器と、を備え、保持器は、転動体の軸と平行の回転軸を中心として回転するピニオンを有し、上下一対の板部材は、それぞれ、対向する側の面にピニオンと噛合するラックを有する。【選択図】図１
