PROBLEM TO BE SOLVED: To provide a rotary plower by opening an oiling port 12 at the upper part of a casing 5 pivoting a rotary-driving shaft 3 and power-inputting shaft 4 and transmitted with the power through a bevel gear mechanism 2, 2a, and installing an oiling plug 13 attached with a breather hole 13a at the oiling port 12 and prevent lubricating oil from leaking through the breather hole 13a. SOLUTION: This rotary plower is provided by forming a first opening port 14 facing in sideways in a state of continuing from the oiling port 12 and a second opening port 14b facing vertically as branching in a casing 5 and making the lubricating oil entering into the first opening port 14 flow down from the second opening port 14b, while making the splash of the lubricating oil by the bevel gear mechanism 2, 2a not directly reach to the oiling port 12.
