To prevent generation of an abnormal sound by restraining looseness of a bush, without increasing an operation load when rotatably operating a fin.

A register for a vehicle includes a retainer, fins for adjusting the wind direction in an air blowout port of this retainer, and a bush for supporting this fin so that rotational operation can be performed and installed inside the retainer, and projections 42 for actively interfering with the retainer 10 and deflection parts 40 elastically deformed when this projections interfere with the retainer 10, are arranged in at least one bush 30 out of the bushes 22 and 30 for individually supporting both end parts of the fin 20.
