a head including a chuck positioned facing the holding unit and the chuck holding the tool held by the tool holder;
an interior case including, in a peripheral wall, a first opening through which the holding unit is inserted and a second opening through which the head is inserted, the interior case housing the workpiece holder, the tool holder, and the chuck disposed inside;
a first cover formed of a soft material and occluding between the holding unit and an outer periphery of the first opening in the interior case;
