Abstract
[Object] Damage to a surface of a resin bush caused by press-fitting is prevented even when a configuration for positioning during welding is added. [Solving Means] A rolled collar () is a steel rolled collar into which a resin bush () is pressed-fitted, and which is joined to a joining member by welding. The rolled collar includes a main body part () formed in a hollow cylindrical shape, and a clinch part that joins both end surfaces of the main body part together by fitting. The rolled collar includes a notch part () formed by cutting off a portion of an annular edge () in the main body part. Here, a convex jig determining a position of the main body part at a time of welding is fit into the notch part. The rolled collar includes a cavity part () formed to be hollow from an inner circumferential surface side on a wall surface around the notch part to form a clearance () between the press-fitted resin bush and an edge portion () of the notch part on the inner circumferential surface side.
