Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a bearing unit and a rotary press device favorable for quality improvement.SOLUTION: A rotary press device (33) includes a restriction section (36) to restrict motion of a roll (30) around a central axis of a roll (30) itself against movement of the roll (30) around a central axis of a hub main body (8) during rotary forging. In an example, the restriction section (36) has guide teeth (44) meshed with teeth formed on a processing surface of the roll (30).SELECTED DRAWING: Figure 2 【課題】品質向上に有利な軸受ユニットの製造方法及び揺動プレス装置を提供する。【解決手段】揺動プレス装置（３３）は、揺動鍛造の際に、ハブ本体（８）の中心軸周りのロール（３０）の動きに抗してロール（３０）自身の中心軸回りのロール（３０）の運動を規制する規制部（３６）を備える。一例において、規制部（３６）は、ロール（３０）の加工面に設けられた歯に噛合されるガイド歯（４４）を有する。【選択図】図２
