A hinge pin 6 is turnably inserted in a through hole 22 formed in a first hinge member 2. A second hinge member 3 is fixed to the hinge pin 6. A movable member 7 is connected to the first hinge member 2 such that said movable member 7 is non-turnable but movable in the axial direction. A convex part 75 is formed on the movable member 7. A concave part 53 is formed in a fixing member 5 of the second hinge member 3. By pressing the convex part 75 against a bottom surface 53a of the concave part 53 under the biasing force of a coiled spring 8, the biasing force of the coiled spring 8 can be converted to a turn biasing force for turning the second hinge member 3 with respect to the first hinge member 2. The hinge pin 6 is press-fitted in the through-hole 22 of the first hinge member 2. This causes to generate a frictional resistance for preventing relative rotation between the first hinge member 2 and the second member 3, between the inner peripheral surface of the through-hole 22 and the outer peripheral surface of the hinge pin 6. This frictional resistance is set to be smaller than the turn biasing force caused by the coiled spring 8. <IMAGE> |
