ール構造。 In a dust seal structure for a rotating shaft, the dust seal structure has a gap between an end face of the bearing part and a facing face of a rotating member pivotally supported by the rotating shaft inserted in the bearing part,
A first flat ring-shaped dust seal made of elastic felt is attached to the end face of the shaft hole of the bearing, and an elastic member is attached to the opposing surface of the rotating member at a position opposite to the first flat ring-shaped dust seal. A second flat ring-shaped dust seal made of felt, one side of which is adhered to the first flat ring-shaped dust seal, and the other side of which is closely connected and rotated with one side of a second flat ring-shaped low-friction resin sheet to be described later. A first flat ring-shaped low-friction resin sheet movably in contact with each other, and a second flat ring-shaped low-friction resin sheet whose other surface is attached to the other surface of the second flat ring-shaped dust seal. The rotating shaft has a dust seal structure.
