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.
