PURPOSE:To improve the efficiency of the production of handles and holders by providing a projecting handle supporting shaft to the holder supporting the cylindrical handle while forming an engaging projection streak on the internal surface of the handle, and then by providing the supporting shaft with an engaged slit. CONSTITUTION:On the internal surface of cylindrical handle 10, engaging projection streak 11 is formed lengthwise and fitted to an equipment body. Holder 10 supporting handle 10 is provided with projecting handle supporting shaft 13 fitted in the end part of the handle. Supporting shaft 13 has engaged slit 14, which can be fitted closely with projection streak 11 in the internal section room, formed extending to its root. Slit 14 is tapered toward its tip and supporting shaft 13 is also tapered toward its tip, so that when projection streak 11 is fitted up to its root, they are in parallel as shown by two-dot chain lines. Slit 14 is so curved at tip part 14a that projection streak 11 is guided smoothly. This structure does not require machining for holes, etc., of the handle and holder, so that the efficiency of the production is improved because of easy manufacture. |
