Abstract

A working unit includes a tool rotation mechanism, a first turning mechanism turning the tool rotation mechanism about a first axis, and a second turning mechanism turning the tool rotation mechanism and the first turning mechanism about a second axis perpendicular to the first axis. The first turning mechanism includes a motor having a stator connected to the second turning mechanism and a hollow shaft-shaped rotor arranged inside the stator in such a manner that the rotor is capable of rotating about the first axis, and a second rotating body including one arm portion coupled to one end portion of the rotor, the other arm portion coupled to the other end portion of the rotor, and an arm coupling portion that couples the arm portions to each other. The tool rotation mechanism is provided on the second rotating body.
