DRIVING MACHINE

The present invention realizes a driving machine equipped with a mechanism for lubricating a pin and a rack. This driving machine 1 has: a driver blade 30 which is capable of reciprocating movement in a first direction and a second direction opposite to each other and which strikes a stopper when moving in the first direction; a pin 44 which engages with a rack 31 provided to the driver blade 30 and which moves the driver blade 30 in the second direction; and a lubricant oil feed mechanism 50 which feeds lubricant oil to the rack 31 and the pin 44. 实现具备润滑销、齿轨的机构的打入机。打入机(1)具有能在相互相反的第一方向以及第二方向上往复移动且在向上述第一方向移动时打击上述紧固件的传动板(30)、与设置于传动板(30)上的齿轨(31)卡合并使该传动板(30)向上述第二方向移动的销(44)以及向齿轨(31)与销(44)供给润滑油的润滑油供给机构(50)。
