Document Type and Number:
Japanese Patent JP3974726
Kind Code:
B2
Abstract:
In a frictional hinge device, a metallic shaft has a rotational axis as a rotational center. A support block is molded in synthetic resin around the metallic shaft so that the support block is rotatably supported by the metallic shaft relatively. The support block is held at any angular position by a surface friction resistance between the support block and the metallic shaft. A shape factor (W) in relation with the metallic shaft and the support block is defined by the following inequality:1.5<=W<=3.5, where W={1+(Do/Dh)2}/{1-(Do/Dh)2}, (Do) is a diameter of the metallic shaft, (Dh) is a diameter or its equivalent of the support block.
