ABSTRACT:
A driving machine having a cylinder fixing arrangement. The driving machine is used for driving a fastener such as a nail into a workpiece. For this, a cylinder-piston arrangement is provided. When the piston is driven to drive the fastener a reaction force is applied to the cylinder. To avoid displacement of the cylinder due to the reaction force, the cylinder fixing arrangement is provided. The fixing arrangement includes a detachable stop washer secured in an annular groove of the cylinder. The stop washer is partly engaged with a flange of the cylinder to prevent the cylinder from its upward displacement. Inner diametrical differences are provided in the cylinder at the position around the stop washer.
