Abstract
A fastener driving machine provided with a mechanism to lubricate pins or racks is realized. A fastener driving machine includes a driver blade, pins, and a lubricant feeding mechanism. The driver blade can reciprocate in a first direction and a second direction opposite to each other, and hits a fastener when the driver blade moves in the first direction. The pins respectively engage with racks provided on the driver blade to move the driver blade in the second direction. The lubricant feeding mechanism supplies lubricant to the racks and the pins.
