Rotary caulking device, method of manufacturing hub unit bearing and method of manufacturing vehicle

A method of manufacturing a hub unit bearing, comprising:

• supporting a hub main body;
• and
• caulking the hub main body to which an inner ring is attached;
• wherein the caulking includes:
• pressing a pressing die on the hub main body while the pressing die rotates;
• and
• moving an outer ring around an axis of the hub main body via an adapter, and
• the adapter includes:
• adapter main body;
• and
• at least one block which is held in the adapter main body, and is disposed to be movable in an axial direction of the hub main body relative to the adapter main body,
• each of the at least one block is disposed to be movable in the axial direction between a protruding state in which the block at least partially protrudes in the axial direction from the adapter main body, and a housed state,
• in the housed state, an axial end face of the block abuts a first surface of the outer ring, and
• in the protruding state, a side surface of the block is disposed to face a second surface that is an outer side surface of the outer ring.
