To provide a machine tool, in which a structure of an apparatus thereof is simple and cost of the whole apparatus can be reduced.
A machining head 29 includes a gear box 100. A work conveying jig 40 includes: a machining power source 101, which is arranged in a jig body part 41 and used for driving the machining head 20; a spline shaft 102 which is extended upward from the machining power source 101 and rotated: a connection part 110 which is arranged at the upper end of the spline shaft 102 and connected to the gear box 100; and an elastic member 103 which is arranged on the machining power source 101 to surround the spline shaft 102 and used for pressing the connection part 110 upward. The machining head is driven by the machining power source, which is arranged in the work conveying jig, whenever machining is performed. Since the number of machining power sources can be minimized, the structure of the apparatus of a machine tool is simple and the cost of the whole apparatus can be reduced.
