Taper implant and a screw-fastening structure using a taper implant with female threads |
摘要 |
A taper implant includes a taper portion having an outer surface frust-conical in shape. A flange portion is formed at an outermost end of the taper portion on the larger-diameter side to project outwardly with respect to the taper portion and having a flat surface situated perpendicularly to the axial direction of the taper portion, and female threads serving as a fit portion extending in the axial direction of the taper portion. A hole taper portion and a hole step portion are drilled at the same time to bore a hole in one of the members to be fastened, and the taper implant is driven into the hole, thereby providing a screw fastening structure for the fastened members.
