Abstract
A driving machine has a work contact portion with an end face to be contacted with a member to be fastened that is provided in a push lever, and a probe movably provided on the work contact portion, wherein the probe is energized in the driving direction by a spring to thereby project its leading end portion from the end face of the work contact portion. When the main body of the driving machine is pressed against a work, the probe is retreated from the driving passage of a fastening member when a tripper switch is operated.
