A hinge device comprises a first hinge member (12, 13) having a hole and a second hinge member (30) having a through bore to receive a torsion bar (50). The member (30) is rotatably mounted in the hole of the first hinge member and connected to one end (52) of the torsion bar by a hook engaged with the bore. The other end of the torsion bar (50) has a hooked end (51) held captive in the hole. Relative rotation of the members is kept to a low speed by viscous grease (80). <IMAGE> |
