The outer race of a rolling bearing with a rolling element interposed between them is inserted, and the dimension C obtained by subtracting the inner radius of the inner race from the inner radius of the metal part is the operating load rating of the rolling element. When the amount of deformation due to the static load rating is δ1, the amount of deformation due to the static load rating is δ2, and the gap dimension formed between the rolling element and the outer race when no load is applied is δ3, the dimensions were set such that δ1+δ3<C<δ2+δ3.
