ROUND REGISTER

摘要

PROBLEM TO BE SOLVED: To improve directivity by reducing the number of part items in a round register and also reducing wind hissing sound. SOLUTION: A round register is provided with a shaft member 2 rotatably journalled on the inner peripheral surface of a cylindrical substrate, and cylindrical members 3 and 4 pivotally supported by the shaft member 2 rotatably in a direction roughly orthogonal to the rotational direction of the shaft member 2. By rotating the shaft member 2 with respect to the cylindrical substrate and the cylindrical members 3 and 4 with respect to the shaft member 2, the direction of air-conditioning air blown out of the cylindrical members 3 and 4 is adjusted.
