A conveying device includes a workpiece pressing member and a switching member. The workpiece pressing member is able to move along a conveyance path when a mobile body moves, and also moves a workpiece downstream of the conveyance path by moving downstream of the conveyance path while pressing the workpiece. The switching member is able to move along the conveyance path as the mobile body moves, and switches between an engaged state and a non-engaged state with the workpiece pressing member depending on whether the movement is in downstream and upstream directions. When the switching member moves downstream, the workpiece pressing member is able to press the workpiece, and, when the switching member moves upstream, the workpiece pressing member is able to avoid coming into contact with the workpiece.
