said at least one second member is two second members,

said two second members are configured to be rotated respectively based on said operation amounts of said two second operating parts, and

said two second members are arranged side by side when seen from the direction perpendicular to said front and rear direction.

4. The attachment device for the suspended member according to claim 1 , wherein

said at least one second member has:

a rotation axis portion fixed rotatably on a first rotation axis perpendicular to said first direction and said second direction relative to said at least one first member;

an effort point portion displaced in said second direction from said first rotation axis and configured to be subjected to force along said first direction based on said operation amount of said at least one second operating part; and

a load point portion displaced in said first direction from said first rotation axis and configured to impose force onto said suspended member, and

a distance between said effort point portion and said first rotation axis is longer than a distance between said load point portion and said first rotation axis.

5. The attachment device for the suspended member according to claim 1 , wherein

said at least one first operating part is a male screw member passing through said at least one first member from said one side in said first direction and being screwed into said fixing member, and

said attachment device further comprises:

at least one first positioning part configured to position said at least one first operating part in said first direction relative to said at least one first member.

6. The attachment device for the suspended member according to claim 1 , wherein

said at least one second operating part is a male screw member passing through said at least one first member from said one side in said first direction,

said at least one second member has:

a rotation axis portion fixed rotatably on a first rotation axis perpendicular to said first direction and said second direction relative to said at least one first member;

an effort point portion displaced in said second direction from said first rotation axis; and

a load point portion displaced in said first direction from said first rotation axis and configured to impose force onto said suspended member, and

said attachment device further comprises:

a positioning part configured to position said at least one second operating part in said first direction relative to said at least one first member; and

a joint member to which said at least one second operating part screws, said joint member fixed rotatably on a second rotation axis parallel to said first rotation axis relative to said effort point portion.

7. The attachment device for the suspended member according to claim 1 , wherein

said at least one second member has a rotation member and a locking member, both the members being fixed to each other rotatably on a first rotation axis perpendicular to said first direction and said second direction,

said rotation member is fixed rotatably on a second rotation axis displaced in said first direction from said first rotation axis in parallel to said first rotation axis relative to said at least one first member, and configured to be rotated based on said operation amount of said at least one second operating part,

said rotation member and said locking member nip a protruding member fixed to said suspended member at least in said second direction at positions displaced in said second direction from said first rotation axis, and

said locking member is rotated relative to said rotation member to release said protruding member in said second direction.

8. The attachment device for the suspended member according to claim 7 , wherein

said first direction is the vertical direction,

said second direction is the front and rear direction perpendicular to said attachment surface,

said at least one first member supports said suspended member at upper portion of said suspended member so that suspended member is rotatable on an axis parallel to the left and right direction perpendicular to said vertical direction and said front and rear direction,
