Abstract
An inner disc portion and an outer disc portion are connected through first to fifth connecting ribs. The second and third connecting ribs which are provided on the outer diameter side are inclined reversely to each other so that a portion where the distance between outer-diameter-side end portions of the second and third connecting ribs is wider and a portion where the distance is narrower are provided alternately. The fourth connecting ribs are provided in the portions where the distance is wider respectively. In addition, each of the fifth connecting ribs are provided between the first connecting ribs and the second and third connecting ribs respectively. The inclination angle &thgr; of the second and third connecting ribs is regulated so that the distances between the end portions of the respective ribs are equal to one another.
