Vehicle wheel having adjustable insert neck and method for manufacturing the same

A vehicle wheel comprising:

• a rim and a disc which are separately molded to be coupled to each other;
• a resonance chamber defined at a boundary between the rim and the disc;
• a forming end configured to enclose the resonance chamber;
• and
• a sound-absorbing hole defined in the forming end such that the resonance chamber and an interior space of a tire communicate with each other through the sound-absorbing hole,
• wherein a hollow insert neck having an inner diameter and a length adjustable according to a target resonance frequency is tightly disposed in the sound-absorbing hole,
• wherein the insert neck includes a first uneven part on a circumferential portion thereof and the sound-absorbing hole includes a second uneven part on an inner diameter portion thereof such that the first uneven part and the second uneven part are engaged and locked to each other,
• wherein the first uneven part includes a first groove and a first protrusion, and the second uneven part includes a second protrusion and a second groove, and
• wherein when the insert neck is press-fitted into the sound-absorbing hole, the first protrusion of the first uneven part is inserted and fastened to the second groove of the second uneven part, and the second protrusion of the second uneven part is inserted and fastened to the first groove of the first uneven part.
