Claims

[Scope of utility model registration request]

A multi-shaft shaft head in which a plurality of tapheads are arranged in parallel and are rotatably driven by a common drive source and are threaded along the axial direction, the master screw shaft being connected to the drive source; A case body that engages with a master screw shaft and is screwed along the axial direction by the rotation of the master screw shaft, a large number of tapheads that are pivotally supported by the case body, and A multi-axis shaft head characterized by being provided with a rotation transmission means for transmitting rotation to a tap head.
