    • A coast brake of the type having a screw cone provided with a tapered part to be screwed into an internal end part of a male screw cylinder to which a chain gear is fixed, the screw cone being removed by means of the rotation of the male screw cylinder. A brake shoe is in mesh with a fixed brake cone which is provided outwardly of the screw cone to engage with a hub body by pressing the brake shoe being expanded. The coaster brake further includes: a cylindrical part smaller in diameter than a top end part of the brake cone being provided on one end part of the brake cone; a clutch spring with a projection being fitted on an outer periphery of the cylindrical part to exert a force in a direction of fastening itself when a negative rotational force works upon the projection around the cylindrical part; and an axial notch part provided on the screw cone, the projection of the clutch spring being in mesh with this notch part.
