The rotation of the band in relation to a boot to be fastened is prevented, so that reduction of the boot-fastening force is prevented, thereby preventing leakage of grease from a boot to be fastened, and so that boot-bands can be manufactured simply. An endless boot-fixing band 1 is formed as an endless ring, and is reduced in diameter by plastic deformation so as to fasten a boot by applying pressure onto said boot's outer surface. The boot band is formed entirely of an Al—Mg—Si alloy, and a surface-pressure-altering part 3, which changes the surface pressure for fastening the boot, is formed on the inner surface of the band.
