HINGE DEVICE

WIPO Patent Application WO/2005/012739

A1

A hinge device holding a rotation-side member at a desired position and having improved operability of rotation, where the device is radially downsized, facilitated in torque adjustment, and has a simple structure. The hinge device has a shaft (13), a friction force-producing mechanism (12), and a torsion bar (14). The shaft (13) supports the rotation-side member (3) so as to be rotatable in the normal and reverse directions relative to a stationary-side member (2). The friction force-producing mechanism (12) retains by a friction force the angle of the rotated rotation-side member (3). The torsion bar (14) axially penetrates through the shaft (13), whose both end portions are directly or indirectly fixed to the stationary-side member (2) and the rotation-side member (3), and stores torque by being twisted as the rotation-side member (3) is rotated in the normal and reverse directions, the torque urging the rotation-side member (3) in the direction opposite the direction of its rotation.
