    摘要： A grease which comprises a base oil containing at least 50% by mass of a diester compound having a total carbon number of 28 to 40 and represented by the general formula (I): R1OOC—(R2)n—COOR3   (I) wherein R1 and R3 each independently represent a C4 to C20 monovalent aliphatic hydrocarbon group, R2 represents a C1 to C20 divalent hydrocarbon group and n is 0 or 1. The grease is excellent in both low-temperature performance and high-temperature performance and has low oil separation tendency even under high centrifugal force (acceleration). In particular, when the grease is used in a rotational transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement property (intermeshing ability) at low temperatures and a prolonged bearing life at high temperatures and is less apt to cause oil separation under high centrifugal force.

    摘要翻译： 含有至少50质量％的总碳数为28〜40，由通式（I）表示的二酯化合物的基油的润滑脂：R1OOC-（R2）n-COOR3（I）其中R1 R 3各自独立地表示C 4〜C 20一价脂肪族烃基，R 2表示C 1〜C 20二价烃基，n为0或1.该润滑脂具有优异的低温性能和高温性能，油分离率低 趋势即使在高离心力（加速度）下。 特别是，在具有内置单向离合器的旋转传动装置中使用润滑脂时，润滑脂能够在低温下提供令人满意的离合器接合性（相互啮合能力），并且在高温下具有延长的轴承寿命并且不太适合 在高离心力下引起油分离。
