PROBLEM TO BE SOLVED: To enlarge a rotation range of a second hinge member with respect to a first hinge member. SOLUTION: On a rotation axis of a first and a second hinge members, a movable member (unillustrated) irrotationally connected to the second hinge member is disposed to be rotatable, and movable in the rotation axis direction. The movable member is energized toward the first hinge member by a coil spring (unillustrated). In a counter surface of the first hinge member to the movable member, a pair of raised wall surfaces 11d and 11d extended in the rotation axis direction are formed, and an end face cam 41 is formed between the raised wall surfaces 11d and 11d. In a facing surface of the movable member to the first hinge member, a pair of abutment arm parts 42a are formed to convert energization of the coil spring into rotational energization force to rotate the movable member. In a lower part of the raised wall surface 11d, a recessed part 11e is formed. A side surface on the lower side of the recessed part 11e is set as part of the end face cam 41.
