<p>There is provided a robot for carrying a substrate in which a contact type vacuum seal is cooled, the vacuum seal is prevented from exceeding a heat resistance temperature, and a trouble of leaking the atmosphere into a carrying chamber maintained in airtight is prevented from being brought about. In a drive apparatus of a robot for carrying a substrate containing a group of arms under a vacuum environment, a drive apparatus 1 for driving to rotate a group of arms 40 is arranged between to an atmospheric side and a vacuum side and is driven on the atmospheric side, the drive apparatus is provided with a contact type vacuum seal 30 between a stationary member and an output member, further, an oil seal 21 is provided on the atmospheric side of the contact type vacuum seal between the stationary member and the output member, a ring-like space 50 is formed by the contact type vacuum seal and the oil seal between the stationary member and the output member, and the stationary member is respectively provided with a supply port 51 of a cooling circulation path from the atmospheric side to the ring-like space and a discharge port 52 of the cooling circulation path from the ring-like space to the atmospheric side.</p> |
