  "textContent": "There is provided a method capable of producing a wheel-supporting rolling bearing unit at low cost. In an event of producing a wheel-supporting rolling bearing unit (), a cylindrical portion () formed in an axial end portion of a hub ring () is inserted through an inner ring (), swing caulking is performed by pressing a die () against a tip end portion of the cylindrical portion () protruding to an axial end portion side more than the inner ring (), and an axial end surface () of the inner ring () is held by a caulked portion () formed by caulking and expanding the tip end portion of the cylindrical portion () radially outward. In such a way, the inner ring () and the hub ring () are fixed integrally witch each other. At this time, a swing angle of the swing caulking is set at 15 degrees or more to 30 degrees or less.",
