Abstract: An operating device rotates a cylindrical rotation body by lever operation to adjust a rotation angle. The operating device includes a lever, the rotation body and an arm. The lever is linearly movable along a direction orthogonal to a rotation axis of the rotation body. The rotation body is rotated by lever operation. The arm is fixed to the rotation body and transmits a movement of the lever as a rotational force to the rotation body. The arm has a shape extending from the rotation body toward the lever in a state where a position of the lever is at the farthest position within a movable range from a reference line passing through a rotation center of the rotation body and orthogonal to a direction which is orthogonal to the rotation axis of the rotation body.
