    摘要： A lifting device lifts and lowers the working unit with respect to an axis of wheels as a center and can move the wheels of the working unit aloft. The lifting device applies to a lawn mowing vehicle comprising a lawn mowing unit and a main body. The lawn mowing unit includes drum wheels that are rotatable about an axis Ax1 extending in a vehicle width direction. The main body is connected to the lawn mowing unit so as to be rotatable about the axis Ax1 and immovable in the axis Ax direction, and can travel with the lawn mowing unit. The lifting device includes a first support member at the lawn mowing unit, a second support member at the main body, and a linear actuator that includes a retractable rod having a front end portion and a main body part having a rear end portion.
