A manufacturing device manufactures a bearing unit including an inner ring member outwardly fitted onto an end portion of a shaft main body of an inner shaft on one side in an axial direction and fixed by a swaged portion extending from the end portion. The manufacturing device includes: a rotating mechanism including a rotor which holds the other side of the inner shaft in the axial direction from below and rotates the inner shaft about a center axis of the inner shaft while the center axis is aligned with an up-down direction, the rotor being mounted below a processing area of the bearing unit; and a swaging mechanism mounted above the processing area and including a punch which is brought into contact with the swaged portion to plastically deform the swaged portion.

A conveying system in a production line for conveying a plurality of objects includes a conveying route. The conveying route comprises first rails and second rails, extending in the different directions and intersecting each other. Each object has a driven portion including a moveable section pivotably supported on the object. The conveying system includes a plurality of conveying units. A first conveying unit has a mechanism for advancing rollers, which are pressed against the driven portion of an object, toward an intersection, when the object travelling on the first rails nears an intersection, and for retracting the rollers from the driven portion when the object enters the intersection. A second conveying unit has a mechanism for advancing the rollers toward the intersection when the object is in the intersection, and for advancing the rollers away from the intersection toward a third conveying unit when both rollers are pressed against the driven portion of the object in the intersection. The intersection has a mechanism for turning the movable section from extending in the direction of the first rails to extending in the direction of the second rails for changing the conveying direction of the object.
