Abstract
A hinge pinis turnably inserted in a through holeformed in a first hinge member. A second hinge memberis fixed to the hinge pin. A movable memberis connected to the first hinge membersuch that said movable memberis non-turnable but movable in the axial direction. A convex partis formed on the movable member. A concave partis formed in a fixing memberof the second hinge member. By pressing the convex partagainst a bottom surfaceof the concave partunder the biasing force of a coiled spring, the biasing force of the coiled springcan be converted to a turn biasing force for turning the second hinge memberwith respect to the first hinge member. The hinge pinis press-fitted in the through-holeof the first hinge member. This causes to generate a frictional resistance for preventing relative rotation between the first hinge memberand the second member, between the inner peripheral surface of the through-holeand the outer peripheral surface of the hinge pin. This frictional resistance is set to be smaller than the turn biasing force caused by the coiled spring
