PROBLEM TO BE SOLVED: To hold a pair of hinge members at first and second positions with click feeling, and to automatically rotate the pair of hinge members from a first position side to a second position side. SOLUTION: A rotating member 3 is rotatably and unmovably mounted on a hinge body 2 through a hinge shaft 4. A movable member 6 is unrotatably and movably mounted on the hinge body 2. The movable member 6 is brought into contact with the rotating member 3 through a cam member 8 by a coil spring 7. The rotating member 3 is provided with a pair of spherical bodies 12A, 12B symmetrically with respect to a point. The movable member 6 has a pair of recessed parts 6b, 6c for fitting the spherical bodies 12A, 12B at the first and second positions. The cam member 8 is connected to the hinge shaft 4 in a state unrotatable within a specific driving angular range between the first and second positions. A cam mechanism 9 is mounted between contact faces of the cam member 8 and the movable member 6 to convert the energizing force of the coil spring 7 into a rotating energizing force to rotate the cam member 8 from the first position side to the second position side.
