摘要： Provided is a radial vane with which manufacturing is possible with superior economy, without incurring a cut loss associated with vane separation in a weld part of a thread bundle. With a longitudinal intermediate part of a contiguous bundle of threads being a fold-over part, both end parts of the fold-over part of the thread bundle are opened into radial shapes and superpositioned, leaving a space in the center part of the fold-over part, a ring-shaped fold-over part (12) is formed within the circumference of the space in the center part thereof. The outer part of the ring-shaped fold-over part (12) is welded in a ring shape, forming a ring-shaped core part (13). A through hole (11) is formed in the inner side of the fold-over part (12), and radial vane parts (14) are formed in which a plurality of thread materials (21) extend outward from the core part (13) toward the outer circumference side from all regions of the circumference direction. The ring-shaped fold-over part (12) is either an un-welded part or an incompletely welded part which protrudes in a dome shape in both surfaces and protrudes in an arch shape into the center, and is also efficacious as a boss part for gap adjustment when a plurality of radial vanes (10) are fixed in an axle, forming a brush head, as well as functioning simultaneously as a slide part which makes fixing easy, and as a grip part which anchors the fixed vanes.
