Abstract
A bearing apparatus includes: two split outer ring halves which are mounted to the housing; a plurality of rolling elements which are provided so as to roll on the two split outer ring halves; and a cage which holds the rolling elements such that the rolling elements are disposed at substantially equal intervals in a circumferential direction of the cage and which is split at a position of the cage to form joint surfaces, an outside diameter of the cage being guided by inner circumferential surfaces of the split outer ring halves. An outside diametrical dimension in a normal direction to the joint surfaces is made larger than an outside diametrical dimension of the cage in a direction parallel to the joint surface, and vicinity of an outside diametrical position of the cage lying in the normal direction is made to be guided by the outer ring halves.
