A cleaning device for a machine tool is provided wherein the machine tool is provided with an automatic tool change mechanism for replacing a tool attached to a main shaft by another tool, and a cutting fluid nozzle for emitting coolant supplied from a coolant pump to a cutting location where a workpiece is machined by a tool. The cleaning device has at least one cleaning nozzle from which clean coolant is sprayed toward portions of the machine tool where adherence of machining chips affects changing of tools. The cleaning nozzle includes a nozzle hole that is open downwards, and an inclined wall that faces the opening of the nozzle hole and is inclined in a direction pointing to the tool. During changing of tools, clean coolant is supplied from the coolant pump to the cleaning nozzles through a filter.
