<P>PROBLEM TO BE SOLVED: To provide a driving machine capable of stably driving a fastener even when a pressure of a pressure accumulation chamber, a type of a nail or hardness of a driven object material changes. <P>SOLUTION: This driving machine 1 includes: a piston 20 and a driver blade 25 for driving a fastener 24; a bumper 50 for absorbing surplus energy when the piston 20 moves to a bottom dead point; a connection member 32 for making the driver blade 25 penetrate to close the lower end of a cylinder 110; and a movable nose 30 for guiding the driver blade 25 fitted in a through-hole of the connection member 32 in the driving direction. The driving machine is structured such that the movable nose 30 is held to be slidable in the driving direction with respect to the connection member 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
