Abstract: The present invention is to provide an industrial robot, which is placed in vacuum for use, capable of efficiently cooling down hand- or arm-driving motors which are arranged inside the arm in air. The industrial robot is provided with a motor for rotating a second arm unit with respect to a first arm unit, a motor for rotating a hand with respect to the second arm unit, a reduction gear for reducing the rotation of the motor and transmitting it to the second arm unit, and a reduction gear for reducing the rotation of the motor and transmitting it to the hand; the hand and the arm are placed in vacuum. The reduction gears and are coaxially arranged so that the center of rotation of the second arm unit with respect to the first arm unit coincides with the axial centers of the reduction gears. The interior space of the hollow first arm unit is kept at atmospheric pressure in which the motors and the reduction gears are arranged.

Abstract: The present application provides an industrial robot that can control the abrasion and damage of a bearing unit, and also control the deformation of an arm, even in the case of transferring a high-temperature transfer object in a vacuum. The industrial robot includes a bearing unit for supporting an arm at a joint section as a connection section between the arm and the main body. At the joint section, the arm has a first protrusion section protruding toward the main body, and meanwhile the main body has a first housing section in which a first hollow section for housing the first protrusion section is formed. The first protrusion section and the first housing section are formed of a material having higher thermal conductivity than the bearing unit has, and a semisolid thermally-conductive substance, having higher thermal conductivity than the bearing unit has, is placed in the first hollow section.

Abstract: A guide device includes a plate on which a first medium is to be placed, and provided above a space in which a container is to be inserted, a moving member that moves along a surface of the plate in a supply direction of the first medium or in an opposite direction, a substantially sheetlike guide member that guides the first medium in the supply direction, and a drawing member that draws the moving member toward the plate. When the container is taken out of the space, the moving member is drawn toward the plate in the opposite direction by the drawing member, and the guide member withdraws to a position superposed on the plate. When the container is inserted in the space, the moving member is pushed in the supply direction by the container, and the guide member protrudes from the position in the supply direction.
