Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an additive for lubricant oil which exhibits excellent extreme pressure property and abrasive resistance even on a severe condition with a high load, is excellent in solubility even when applied to hydrocarbon-based base oil, ans is ashless.SOLUTION: An additive for lubricant oil is represented by the following general formula (1). In formula (1), Rrepresents an alkylene group; Rand Reach independently represents a hydrocarbon group; m represents 0 or 1; n represents 0 or 1; and provided that m+n is 1.SELECTED DRAWING: None 【課題】高荷重の過酷な条件下でも優れた極圧性及び耐摩耗性を示し、炭化水素系基油に適用した場合においても溶解性に優れる、無灰の潤滑油用添加剤を提供すること。【解決手段】下記一般式（１）で表される、潤滑油用添加剤。［式（１）中、Ｒ１はアルキレン基、Ｒ２及びＲ３はそれぞれ独立に炭化水素基を示す。ｍは０又は１を示し、ｎは０又は１を示す。ただし、ｍ＋ｎは１である。］【選択図】なし
