Abstract: There is disclosed a toroidal winding apparatus for winding an elongated conductor such as, for example, wire strip or the like, into a coil around an enclosed trunk of a magnetic core having a central opening defined by the trunk which is comprised of a magazine for storing the conductor by winding the same around the outer periphery thereof, said magazine has an aperture provided for pulling out the stored conductor inwards in a radial direction thereof, a magazine stand for supporting the magazine rotatable around the axis thereof which has a space for setting the blank magnetic core therein to allow the magazine to rotate passing through the opening of the core, means for exerting a braking force onto the conductor passing through said aperture, a tension slider being guided movably along the periphery of the magazine, a guide means for guiding the conductor having been pulled out from the aperture, and means for biasing the tension slider in a direction along which distance between the aperture and the t
