Abstract
One end portion and the other end portion of a rotating member, which face each other and form a joint portion, have a shape with projections and recesses. Projections of one end portion fit in recesses of the other end portion, while projections of the other end portion fit in recesses of the one end portion, so that the one end portion and the other end portion are interlocked. The projections have a first corner portion rounded in an arc, while the recesses have a second corner portion rounded in an arc in which the first corner portion fits. The first corner portion has a larger radius of curvature than that of the second corner portion.
