HINGE MECHANISM

PROBLEM TO BE SOLVED: To provide a hinge mechanism capable of reducing the number of components, so as to simplify constitution, capable of securing precision of an operation, capable of saving a space, and capable of reducing manufacturing processes and a manufacturing expense. SOLUTION: This hinge mechanism 10 includes an opening and closing body 12 rotated around an opening and closing shaft 11 as the center, and a support body for journaling the opening and closing shaft 11. An outer circumferential face of the opening and closing body 12 is formed with a receiving part 13 comprising a plane along the opening and closing shaft 11, and a protrusion 14 adjacent to the receiving part 13 around the opening and closing shaft 11, and set with a distance up to the opening and closing shaft 11 getting longer than a distance from the receiving part 13 to the opening and closing shaft 11. The support body is formed with a support face abutting on the outer circumferential face, and is provided with the first energizing means for energizing the opening and closing shaft 11 and the support face to be approached each other, and of allowing approach and separation due to an elastic deformation.
