<p>PROBLEM TO BE SOLVED: To provide a resonator which can suppress manufacturing costs while dealing with a plurality of wheels of different sizes.SOLUTION: A resonator includes a resonator body 36 which has a longitudinal direction along a circumferential direction of a wheel and in which a sub air chamber 44 is provided inside. The resonator body 36 includes a communication part 37 for communicating the sub air chamber 44 with an air chamber. In the resonator body 36, a hinge part 42 is provided which makes the resonator body 36 deformable along an outer periphery of the wheel. When engaging a resonator 12 by engaging parts 47, 47 at both side parts with respect to a plurality of wheels of different sizes, the hinge part 42 deforms in a follow-up manner and mounting can be performed with good accuracy, so that the resonator can deal with the plurality of wheels of different sizes. Manufacturing costs can be suppressed compared with the case in which resonators of mutually different types are manufactured corresponding to the wheel of each size.</p> |
