GLOVE BOX

PURPOSE: To manufacture good products including an electric lamp by connecting the partial range of a primary workpiece to an inner room, making a machining device accessible to the partial range and taking measures for machining another partial range with a working machine arranged outside the inner room. CONSTITUTION: This glove box has a bottom portion 11 forming an inner room 12 closed with air tightness, side portions 10b and a cover portion 10a. The bottom portion 11 is supported in a rotatable manner and provided with a product holder 14 having a through-duct adapted to be closed with air tightness. The product holder 14 is arranged concentrically with the rotating axis of the bottom portion 11. The partial range of a primary workpiece machined in an atmosphere of wearing a protecting glass is connected to the inner room 12. A machining device 16 mounted inside the glove box is made accessible to the partial range. The primary workpiece to be machined is held by the product holder 14 for machining another partial range with a working machine arranged outside the inner room 12.
