<p>Provided is a rotatable balloon sign that can easily rotate and minimize noise caused by rotation of the balloon sign. The rotatable balloon sign has a fixing portion in which a lamp and a blower are disposed, and a display portion rotatably disposed on an upper side of the fixing portion with a rotation member being disposed therebetween, characterized in that the rotation member includes a ring-shaped rotation belt (30) rotatably coupled to a protrusion (12) together with a bearing (32) integrally provided to the rotation belt (30), the protrusion (12) protruding from a top surface of the fixing portion (10) and spaced inwardly from an outer circumference of the fixing portion (10), a rotation plate (40) coupled to an upper side of the rotation belt (30) for covering an upper portion of the protrusion (12), the rotation plate (40) having an inner circumference in which gear teeth (42) having a constant pitch are formed and an outer circumference attached to the display portion (20), and a speed-reducing motor (50) coupled to an inner circumference of the fixing portion (10) for rotating the rotation plate (40) at a constant velocity.</p> |
