Abstract
A machine tool is equipped with a second supply pipe having elasticity and having one end side fixed to a spindle head and the other end side fixed to an arm portion, a cover provided within a machining area, and rollers. When the spindle head is moved in a direction to come close to the arm portion, the second supply pipe is bent and then a portion of the second supply pipe is brought into abutment against the cover. The rollers are provided at a portion of the cover against which the second supply pipe is brought into abutment, and are configured to reduce friction between the cover and the second supply pipe when the second supply pipe moves relative to the cover in an abutment state against the cover.
