An engaging pair (15, 16) of hook-shape in cross section with the members thereof disposed parallel with each other and projecting face to face are installed on the same surface of a base plate (12). The flanges of needle units are inserted in a groove between the members of the engaging pair (15, 16) and held therein. The openings in the needle units are covered by the base plate (12). |
