An operating device includes: a first lever rotatable around a rotation axis; a torsion bar having a columnar shape or a tubular shape with the rotation axis as a central axis and connected to the first lever; and a support that fixes and supports one end of the torsion bar. Further, the operating device includes: a drive shaft having a tubular shape with the rotation axis as a central axis and surrounding a periphery of the torsion bar, one end serving as the first lever side being connected to the first lever, and another end opposite to the one end serving as the first lever side being rotatably supported around the rotation axis; and a plurality of second levers connected to the drive shaft and rotatable around the rotation axis on the support side rather than the first lever.
