Abstract

See full text

Provided is a working machine with improved durability. A nail driver (working machine) includes a hitting portion that is formed in a rod shape extending about an axis line, an injection portion that abuts on an outer peripheral surface of the hitting portion, thereby guiding a movement of the hitting portion toward one side in the axial direction, and a supply portion that energizes a fastener toward one side in a direction intersecting with the axial direction, thereby supplying the fastener to the injection portion. The hitting portion has a tip part, and a center part provided at a position different from that of the tip part in the axial direction. At least a part of an outer peripheral surface of the tip part (tip part outer peripheral surface) on an anti-feeder side with respect to the axis line protrudes from an outer peripheral surface of the center part (center par outer peripheral surface) on a supply portion side with respect to the axis line.
