An operating device (52; 152) comprising: a lever rotatable about a rotating axis; a first torsion bar (21; 121) having a columnar shape or a tubular shape whose central axis is the rotating axis, the first torsion bar (21; 121) being connected to the lever ; a second torsion bar (22; 122) having a columnar shape or a tubular shape and connected to one end of the first torsion bar (21; 121); and a support (24; 124) fixedly supporting the second torsion bar (22; 122) at an end opposite to an end at which the second torsion bar (22; 122) is connected to the first torsion bar (21; 121), characterized by a first pedestal portion structured to sandwich the support (24; 124) with a central axis of the second torsion bar (22; 122) interposed, the first pedestal portion supporting the support (24; 124) such that the support (24; 124) is rotatable about the central axis; a second pedestal portion provided at a position, the position being separated from the second torsion bar (22; 122) in a direction perpendicular to a sandwiching direction in which the first pedestal portion sandwiches the support (24; 124), the position of the second pedestal portion in a direction parallel to the sandwiching direction being different from a position of the second torsion bar (22; 122), the second pedestal portion including a penetrating portion extending through the second pedestal portion toward the support (24; 124); a bolt including a shank passing through the penetrating portion , the bolt being screwed into the support (24; 124) in the direction parallel to the sandwiching direction; and a nut attached to the shank between the second pedestal portion and a head of the bolt . a lever rotatable about a rotating axis; a first torsion bar (21; 121) having a columnar shape or a tubular shape whose central axis is the rotating axis, the first torsion bar (21; 121) being connected to the lever ; a second torsion bar (22; 122) having a columnar shape or a tubular shape and connected to one end of the first torsion bar (21; 121); and a support (24; 124) fixedly supporting the second torsion bar (22; 122) at an end opposite to an end at which the second torsion bar (22; 122) is connected to the first torsion bar (21; 121), characterized by a first pedestal portion structured to sandwich the support (24; 124) with a central axis of the second torsion bar (22; 122) interposed, the first pedestal portion supporting the support (24; 124) such that the support (24; 124) is rotatable about the central axis; a second pedestal portion provided at a position, the position being separated from the second torsion bar (22; 122) in a direction perpendicular to a sandwiching direction in which the first pedestal portion sandwiches the support (24; 124), the position of the second pedestal portion in a direction parallel to the sandwiching direction being different from a position of the second torsion bar (22; 122), the second pedestal portion including a penetrating portion extending through the second pedestal portion toward the support (24; 124); a bolt including a shank passing through the penetrating portion , the bolt being screwed into the support (24; 124) in the direction parallel to the sandwiching direction; and a nut attached to the shank between the second pedestal portion and a head of the bolt . <EOS>
