To provide a grinding apparatus capable of effectively preventing a ring-shaped member from having a chatter on an outer peripheral surface.SOLUTION: A grinding apparatus comprises: a rotary drive shaft of a ring-shaped member 6; a grindstone 5 for grinding an outer peripheral surface of the ring-shaped member 6; and a pair of shoes 7c, 7d for supporting the outer peripheral surface of the ring-shaped member 6 at a part deviating circumferentially from a part to be ground with the grindstone 5, and causes, when grinding the outer peripheral surface of the ring-shaped member 6 with the grindstone 5, moment M to operate on the ring-shaped member 6 in a direction in which the outer peripheral surface of the ring-shaped member 6 is pressed toward the first shoe 7c which is on a side closer to the grindstone 5 between the pair of shoes 7c, 7d.SELECTED DRAWING: Figure 1 【課題】リング状部材の外周面にビビリが発生するのを有効に防止することができる研削装置を提供する。【解決手段】研削装置は、リング状部材６の回転駆動軸と、該リング状部材６の外周面を研削するための砥石５と、該リング状部材６の外周面のうち、該砥石５により研削される部分から円周方向に外れた部分を支持する１対のシュー７ｃ、７ｄとを備え、該リング状部材６の外周面を砥石５により研削する際に、リング状部材６に対し、該リング状部材６の外周面を、該１対のシュー７ｃ、７ｄのうち、該砥石５に近い側の第１のシュー７ｃに向けて押し付ける方向のモーメントＭを作用させる、ことを特徴とする。【選択図】図１
