Provided is a driving apparatus capable of effectively preventing impact at the stroke end in the hydraulic cylinder. The driving apparatus includes a hydraulic pump, a cylinder control valve, an operation member, a drive command input unit inputting a cylinder drive command corresponding to a cylinder operation applied to the operation member to the cylinder control valve, a cylinder stroke detection unit, a cylinder drive command restriction unit restricting the cylinder drive command in response to the cylinder stroke to stop a piston of a hydraulic cylinder before the stroke end.
