1. A hinge device attached to a fold/unfold apparatus where said device has a fold/unfold body making folding and unfolding operations about a rotational center shaft with respect to a main body, comprising: a pair of hinge units each including: a hinge base that has a rotational shaft portion serving as a rotational center shaft, and that is attached to the main body of the fold/unfold apparatus; anda holder that has a rotational shaft hole through which the rotational shaft portion passes, and that is attached to the fold/unfold body to be integrally rotated,wherein the pair of hinge units are arranged such that both hinge bases are connected together through a hinge base connecting part according to a distance between both holders,wherein the holders of the pair of hinges are attached to the fold/unfold body in such manner that each said rotational shaft portion is disposed in fixed relation with a bottom edge of said fold/unfold body, and provides an axis of rotation about which said fold/unfold body is rotatable a range of at least 90 degrees with respect to the main body,wherein each of the pair of hinge units includes a click washer located between the hinge base and the holder, through which the rotational shaft portion passes, rotated integrally with the holder, and having one of a clicking recess and a clicking projection,wherein the hinge base is provided with the other of the clicking recess and the clicking projection that engages with the one of the clicking recess and the clicking projection of the click washer to produce a clicking action on a circumference centered about the rotational center shaft,wherein the rotational shaft portion is arranged such that the hinge base is protrusively provided by a burring process,wherein the pair of hinge units are arranged such that both holders are connected together through a holder connecting part, and that both rotational shaft portions are protrusively provided on the faces on one same directional side of both hinge bases, respectively, and that both holders are assembled to both rotational shaft portions from the one directional side, respectively, andwherein the burring processed portion of the hinge base is swaged to fix the holder, hinge base and click washer. 2. The hinge device according to claim 1, wherein the holder has a stopper that abuts against the hinge base to restrain the folding and unfolding of the fold/unfold body, when the holder is rotated to a predetermined rotational angular position. 3. The hinge device according to claim 1, wherein the hinge device has a mounting member that is located between both hinge bases, and that secures the hinge base connecting part to the fold/unfold apparatus. 4. A hinge device attached to a fold/unfold apparatus where said device has a fold/unfold body making folding and unfolding operations about a rotational center shaft with respect to a main body, comprising: a pair of hinge units each including: a holder that has a rotational shaft portion serving as a rotational center shaft, and is attached to the fold/unfold body to be integrally rotated; anda hinge base that has a rotational shaft hole through which the rotational shaft portion passes, and is attached to the main body of the fold/unfold apparatus,wherein the pair of hinge units are arranged such that both hinge bases are connected together through a hinge base connecting part according to a distance between both holders,wherein the holders of the pair of hinges are attached to the fold/unfold body in such manner that each said rotational shaft portion is disposed in fixed relation with a bottom edge of said fold/unfold body, and provides an axis of rotation about which said fold/unfold body is rotatable a range of at least 90 degrees with respect to the main body,wherein each of the pair of hinge units includes a click washer located between the hinge base and the holder, through which the rotational shaft portion passes, rotated integrally with the holder, and having one of a clicking recess and a clicking projection,wherein the hinge base is provided with the other of the clicking recess and the clicking projection that engages with the one of the clicking recess and the clicking projection of the click washer to produce a clicking action on a circumference centered about the rotational shaft hole,wherein the rotational shaft portion is arranged such that the holder is protrusively provided by a burring process,wherein the pair of hinge units are arranged such that both holders are connected together through a holder connecting part, and that both rotational shaft portions are protrusively provided on the faces on one same directional side of both holders, respectively,and that both holders are assembled to both hinge bases from the one directional side, respectively, andwherein the burring processed portion of the holder is swaged to fix the holder, hinge base and click washer. 5. The hinge device according to claim 4, wherein the holder has a stopper that abuts against the hinge base to restrain the folding and unfolding of the fold/unfold body when the holder is rotated to a predetermined rotational angular position. 6. The hinge device according to claim 4, wherein the hinge device has a mounting member that is located between both hinge bases, and that secures the hinge base connecting part to the fold/unfold apparatus. 7. The hinge device according to claim 1, further comprising: dislocation-restraining sections that extend upwardly from two end positions of the holder connection part, respectively, to prevent dislocation of the fold/unfold body. 8. The hinge device according to claim 4, further comprising: dislocation-restraining sections that extend upwardly from two end positions of the holder connection part, respectively, to prevent dislocation of the fold/unfold body. 9. The hinge device according to claim 1, wherein the hinge base of each of the pair of hinge units is provided with a guide groove to which the one of the clicking recess and the clicking projection of the click washer engages, the guide groove being provided on a circumference on which the other of the clicking recess and the clicking projection is provided. 10. The hinge device according to claim 4, wherein the hinge base of each of the pair of hinge units is provided with a guide groove to which the one of the clicking recess and the clicking projection of the click washer engages, the guide groove being provided on a circumference on which the other of the clicking recess and the clicking projection is provided.
