Abstract
An internal pressure adjustment system includes a gas supply line that supplies incombustible gas to a housing space of a robot, and an exhaust line that exhausts gas from the housing space. The internal pressure adjustment system further includes an on-off valve of a gas pressure driven type that switches between opening and closing of the exhaust line in accordance with the gas supply pressure. The exhaust line is opened in response to an increase in the gas supply pressure and the exhaust line is closed in response to a decrease in the gas supply pressure.
