<p>A hinge shaft (6) is turnably inserted in a through hole (22) in a first hinge member (2). A second hinge member (3) is fixed to the hinge shaft (6). A movable member (7) is connected to the first hinge member (2) non-turnably and axially movably. The movable member (7) is formed with a projection (75). A fixing member (5) for the second hinge member (3) is formed with a recess (53). The projection (75) is pressed against the bottom surface (53a) of the recess (53) by the urging force of a coil spring (8), whereby the urging force of the coil spring (8) is converted into a turning urging force tending to turn the second hinge member (3) relative to the first hinge member (2). The hinge shaft (6) is press-fitted in a through hole (22) in the first hinge member (2). Thereby, a frictional resistance tending to prevent relative rotation between the first hinge member (2) and the second hinge member (3) is produced between the inner peripheral surface of the through hole (22) and the outer peripheral surface of the hinge shaft. It is arranged that the size of this frictional resistance is smaller than that of the turning urging force produced by the coil spring (8).</p> |
