ABSTRACT:
A buffering device used in a hinge structure of a lid or cover, such as stool lid of a toilet stool of Western style, which is pivoted on a horizontal axis and generally opened upwards by hand and closed downwards by gravity, comprising two members such as of coaxial cylinder type having mutually facing surfaces, respectively, and being combined coaxially to enable relative rotation, and at least one idle member disposed within a gap between the facing surfaces to roll with the relative rotation, and including no buffering fluid, in which the torque for closure is made large as compared with the torque for opening, so that the lid can be opened lightly when it is opened by hand, while it is automatically braked for preventing it from colliding against the stool body to produce an undesirable strike sound when it is naturally closed by gravity.
