1. A robot comprising a lubricant chamber in which a fluid lubricant can be stored, wherein
the lubricant chamber is provided with three or more through-holes that extend through wall surfaces of the lubricant chamber, and
the through-holes are disposed such that, in a state in which any one of the through-holes is disposed at a lowest level of the lubricant chamber so as to allow a utilization thereof as an oil discharge hole in two or more orientations of the lubricant chamber, another one of the through-holes is disposed at a position corresponding to a liquid level of the lubricant when a required amount of the lubricant is stored in the lubricant chamber so as to allow a utilization thereof as a vent hole, and a remaining one of the through-holes is disposed at a position that allows a utilization thereof as an oil supply hole from which the lubricant is supplied into the lubricant chamber.
