摘要： [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 (40) is a steel rolled collar into which a resin bush (90) is pressed-fitted, and which is joined to a joining member by welding. The rolled collar includes a main body part (50) 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 (70) formed by cutting off a portion of an annular edge (53) 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 (80) formed to be hollow from an inner circumferential surface side on a wall surface around the notch part to form a clearance (81) between the press-fitted resin bush and an edge portion (71) of the notch part on the inner circumferential surface side.
