The present invention provides a speed reducer, trying for improving cooling performance of a cooling device and trying for unification of members simultaneously, so as to trying for miniaturization of the speed reducer and reducing cost. In the speed reducer (100) having a gear box (102), the gear box (102) is provided with a leading-in hole (128) of cooling medium for lubricant and a leading-out hole (130) of the cooling medium, simultaneously, a cooling piping (132) for leading-out of the cooling medium through the leading-out hole (130) that the cooling medium is guided inwards through the leading-in hole (128) is arranged inside the gear box (102), and an adjustment mechanism for adjusting a distance between the cooling piping (132) and gears (120, 126) arranged in the gear box (102)is also arranged inside the gear box (102). |
