Steering device and industrial vehicle

A steering device used to steer a vehicle, the steering device comprising:

• a rotation central portion that includes a rotation axis of the steering device;
• and
• a steering unit that is connected to the rotation central portion, wherein
• a direction in which the rotation axis of the rotation central portion extends is referred to as an axial direction,
• one of directions that are perpendicular to the axial direction is referred to as a radial direction,
• a direction that is perpendicular to the axial direction and the radial direction is referred to as a width direction,
• the steering unit protrudes from the rotation central portion in the radial direction in a plan view of the steering device in the axial direction,
• the steering unit includes an arm and a grip in the plan view of the steering device in the axial direction, the arm extending from the rotation central portion in the radial direction, and the grip being connected to a tip of the arm and extending at least in the axial direction,
• a width of the arm in the width direction decreases as a distance from an end of the arm connected to the rotation central portion toward the tip of the arm increases, and
• a maximum width of the steering unit in the width direction is less than or equal to a maximum width of the rotation central portion in the width direction.
