上記従来例における内圧防爆構造では、各アーム内に形
成された気密室内にアーム駆動用の電動式のモータが装
備されており、上記各気密室は、内部に配線を内蔵した
密封状のホースによって連通されている。In the conventional internal pressure explosion-proof structure described above, an electric motor for driving the arm is installed in an airtight chamber formed in each arm, and each airtight chamber is connected to a sealed hose with internal wiring. It is communicated.
