<p>PROBLEM TO BE SOLVED: To provide a wheel for a two-piece type vehicle capable of equipping a plurality of resonators at low cost for absorbing columnar resonance energy of a tire inner space.SOLUTION: A wheel 1 for a two-piece type vehicle comprises a rim 10 to which a tire is mounted and a disc 20 forming a separate body from the rim 10 and fixed to the rim 10. A flange part 22 of the disc 20 comprises a fitting-in part 22a fitted in a well part 11 (a rim minimum diameter part) of the rim 10 and an extension part 22b extending inward in a central axis direction from the fitting-in part 22a. A sub-air chamber 41 is formed between the extension part 22b of the disk 20 and an opposed surface of the rim 10. The rim 10 is formed with a communication hole 42 for communicating the sub-air chamber 41 with a main air chamber 2 composed of an inner space of the tire, and the resonator 40 is constituted by the sub-air chamber 41 and communication hole 42.</p> |
