Abstract
Within the hermetically sealed interior of a housing 9, a driving bevel gear 15 is fixedly secured to an input shaft 12 coupled via a rotation transmission cable 5 to an output shaft of a drive unit. A spindle 19 rotates jointly and coaxially with the driving bevel gear 15, which meshes with a driven bevel gear 17 coupled in such a manner as to allow a relative displacement in the axial direction. The spindle 19 has an externally threaded portion 19A screwed in an internally threaded portion 20A of a master metal 20. The spindle 19 has one end protruding from the housing 9 to the exterior, the one end being provided with a spindle chuck 21 for retaining a tap T.
