A support shaft of a spindle unit having a through hole in which wires are laid has a structure that can obtain much spatial room so as to prevent a break in cables and to be compatible with a high-output spindle motor. A machine-tool spindle headincludes a support headthat drives a spindle unitfor indexing around a turn axis (A-axis) of the spindle unitby rotatably supporting a pair of support shaftscoupled to the spindle uniton the A-axis by a pair of fork armsand bearings. The pair of support shaftshave through holesin which a plurality of wiresextending from the spindle unitare laid, the plurality of wiresare divided into two wire groups, and the wire groups are separately laid in the pair of support shafts
