ROLLING BEARING DEVICE, BEARING STRUCTURE, SEISMICALLY ISOLATED STRUCTURE, AND VIBRATION CONTROL STRUCTURE

摘要

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.
