Abstract
A robot includes: a first arm having a first body, a first housing fixed to the first body, and a first gear transmitting power to a rotary member supported by the first housing so as to be rotatable; a second arm supporting the first arm and having a second body, a second shaft having a second gear meshing with the first gear, and a second bearing supporting the second shaft so that the second shaft is rotatable relative to the second body; and a channel in the arms. An inlet of the channel is formed in an outer surface of the first body, an outlet of the channel opening into a space in which an outer peripheral surface of the second shaft and the second bearing are arranged inside the second arm, the channel extending from the inlet to the outlet through inside of the first body.
