Abstract
An internal-pressure rise prevention structure of a speed reducer according to the invention includes a speed reduction mechanism that decelerates rotation of an input part and transmits the decelerated rotation to an output part, and a container having a communication hole formed in a wall surface that defines an internal space for accommodating the speed reduction mechanism and lubricant. The communication hole is situated vertically above the level of the lubricant.
