Abstract
A liquid drainage mechanism drains oil (liquid) from a Y-axis slider that moves along a predetermined path. The liquid drainage mechanism includes an outflow hole and a nozzle flow passage that are provided in a C-axis rotary mechanism and configured to flow the oil in a stator, a nozzle configured to move integrally with the Y-axis slider and discharge the oil, and a Y-axis guide member configured to guide the Y-axis slider. The nozzle is disposed at a position that is close to but not in contact with the Y-axis guide member, and the nozzle discharges the oil so that the oil reaches the Y-axis guide member.
