[Problem] To prevent damage to the surface of a resin bush caused by press-fitting, even when a configuration for positioning during welding is added. [Solution] A steel winding collar (40) to which a resin bush (90) is press-fitted, and which is joined to a joining member by welding. The winding collar includes a main body (50) that is formed in a hollow tubular shape, and a clinch part that is formed by joining both end surfaces of the main body by engaging both end surfaces with each other. The winding collar includes a notch (70) that is formed by cutting out part of an annular edge (53) of the main body, and into which a protruding jig for main body positioning during welding is fitted. The winding collar includes a cavity (80) that is formed in a circumferential wall surface of the notch and is depressed from the inner circumferential surface side thereof, and that forms a clearance (81) between an edge part (71) of the inner circumferential surface side of the notch and the resin bush which is press-fitted.
