Abstract: A robot arm includes a first member, a second member, an actuator, and a speed reducer. The second member is pivotable relative to the first member about a pivot axis. The actuator is configured to pivotally move the second member relative to the first member about the pivot axis. The speed reducer is configured to couple the actuator to the second member to reduce a rotational speed of the second member relative to an output rotational speed of the actuator. The speed reducer includes a grease chamber in which grease is to be provided. The second member including an air chamber in which air is provided, the air chamber being connected to the grease chamber.

Abstract: A cable includes electric wires, an outer cover, a first cover, and a second cover. Each of the electric wires includes a conductive core and an insulator covering the conductive core. The outer cover covers the electric wires and extends from a first atmosphere to a second atmosphere less explosive than the first atmosphere. An outer surface of the outer cover is supported by a partition separating the first atmosphere from the second atmosphere. The first cover includes a thermosetting resin and covers an exposed portion of the electric wires, which is not covered by the outer cover in the second atmosphere. The second cover covers the first cover and includes a material higher in fracture strength than the thermosetting resin.
