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 (31,32), a cylinder control valve (37,38), an operation member (47a), a drive command input unit (34, 47b) inputting a cylinder drive command corresponding to a cylinder operation applied to the operation member (47a) to the cylinder control valve (37,38), a cylinder stroke detection unit (50,70), a cylinder drive command restriction unit (42A,42B, 50) restricting the cylinder drive command in response to the cylinder stroke to stop a piston (27p) of a hydraulic cylinder (27) before the stroke end.
