PROBLEM TO BE SOLVED: To provide a rotating body which has adhesiveness of a body part with a steel plate equal to or larger than that of a rotating body of a conventional technique and enables cost reduction.SOLUTION: A rotating body for a molten metal plating bath has an approximately columnar body part and is incorporated into a molten metal plating apparatus for plating a steel plate with molten metal. The body part includes a large diameter region and a diameter reduced region which is arranged at least on one end side of the large diameter region in the longitudinal direction and whose external diameter is reduced from the center of the body part toward the end thereof. The edges of the outer peripheries of the large diameter region and the diameter reduced region are directly connected to each other in a cross section along the longitudinal direction. |
