  • CUP-SHAPED MEMBER INCLUDING INNER PERIPHERAL CORRUGATED PORTION AND MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR THE SAME
    Publication number: 20130059166
    Abstract: A cup-shaped member in which the outer peripheral recesses are formed on the base end portion side of the outer peripheral surface of the cylinder portion, on which the bottom portion is disposed, by denting the outer peripheral surface radially inward of the cylinder portion at positions that correspond to the inner peripheral protrusions. The smooth outer peripheral portion is formed on the opening end side of the outer peripheral surface of the cylinder portion that is opposite to the side on which the bottom portion is disposed. The smooth outer peripheral portion has no corrugation and has generally the same diameter over the entire circumference of the outer peripheral surface, thereby increasing the strength of the cup-shaped member, and allowing the inner peripheral corrugated portion to be surely formed.
