Disclosed is a trochoid lubricant supply device that is configured to connect to a rotational shaft. A connector of the lubricant supply device is configured to reduce an oil leakage amount of lubricant, and is configured to insert to a lower portion of a rotational shaft. The connector includes: a rotator mounting member inserted into and fixed to the rotator of the lubricant supply device; a penetrating member that penetrates a fixer of the lubricant supply device; an enlarged diameter extending radially outwards from the penetrating member outside the fixer; and a rotational shaft mounting member extending axially in the diameter enlarged member and is fastened to the rotational shaft. Further, the lubricant supply device of the present disclosure can supply the oil regardless of a rotation direction of the rotational shaft by supplying the oil by a space pivoting about the rotational center of the rotator.
