SPEED REDUCER, ROTARY DRIVE SYSTEM, AND HYDRAULIC SHOVEL
A speed reducer is provided with: a transmission section (80) that rotates around an axis; an annular member (170) that has a cylindrical shape surrounding the axis and that rotates together with thetransmission section (80) around the axis, said annular member (170) having formed therein an oil sump comprising a recessed groove recessed into the inner circumferential surface thereof, and a lubricating oil supply hole that extends and opens toward the radially outward side from the recessed groove; and a sliding section provided to the radially outward side of the lubricating oil supply holeof the annular member (170).
具备：传递部(80)，其绕轴线旋转；环状构件(170)，其形成为围绕轴线的筒状并与传递部(80)一起绕轴线旋转，并且，形成有具有向内周面凹陷的凹槽的贮油部及从凹槽朝向径向外侧延伸并开口的润滑油供给孔；以及滑动部，其设置在该环状构件(170)的所述润滑油供给孔的径向外侧。
