Abstract
A vertically reciprocatable needle (41) that is extremely fine in its lengthwise direction, having a leading end portion of a triangular pyramidal shape. Edges (41b) are formed on a periphery of the leading end portion, and an engaging portion (41c) is formed at a base thereof. The engaging portion comprises a recess (41d) and a tongue (41e) covering the recess. Below the engaging portion, a tapered guide surface (41f) continues straight from a point on a periphery of the needle to the recess. The recess is recessed in a needle axial direction. The tongue has a diameter smaller than the maximum diameter of the guide surface. The artificial hair may be hooked by the engaging portion during vertical movement of the needle, which assures relative movement of the needle at a pitch or width of high accuracy. Accordingly, the transplanting pitch of the artificial hair is controlled with high accuracy.
