description PROBLEM TO BE SOLVED: To provide a noise reduction rim which does not cause the problem for mounting to the rim of a tire, and the manufacturing method of the noise reduction rim which can form a projection part with a simpler device than a cotter, and a slide jaw type manufacturing device. SOLUTION: The noise reduction rim 10 has a plurality of projection parts 12 projecting to a cavity between the tire and the rim each other at an interval in the peripheral direction of the rim at a part of the axial direction of the rim of a rim drop part 11, and integrally formed to the rim by forming a wall itself of the drop part 11 by the projection parts 12. The manufacturing method of the noise reduction rim 10 has a projection part processing process which press-forms the plurality of projection parts 12 projecting to the cavity between the tire and the rim each other at the interval in the peripheral direction of the rim at the part of the axial direction of the rim drop part 11 before forming of the expand after roll forming of the rim. Since the forming of the projection part is only the part of the axial direction of the rim of the rim drop part, the tire can be mounted to the rim by dropping a tire bead to the part where the projection parts are not formed in the axial direction of the rim among the rim drop part.
