Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a grease composition and a rolling device encapsulating the grease composition suppressing dissolution of lithium soap even at high temperature over 180°C and maintaining grease shape by blending a boron-containing compound with the grease composition containing lithium soap as a thickener, and extremely excellent in high temperature property compared to conventional lithium soap-based grease while maintaining acoustic property of lithium soap.SOLUTION: The grease composition is a grease composition containing a base oil and a thickener, a boron-containing compound is blended with the grease composition and lithium soap is contained as the thickener. 【課題】本発明のグリース組成物、前記グリース組成物を封入した転動装置は、リチウム石けんを増ちょう剤とするグリース組成物にホウ素含有化合物を配合することにより、１８０℃を超えるような高温においてもリチウム石けんの溶解を抑制し、グリース状を保つため、リチウム石けんの音響特性を維持したまま、従来のリチウム石けん系グリースと比較して高温特性に著しく優れる。【解決手段】本発明によるグリース組成物は、基油と増ちょう剤を含有するグリース組成物であり、前記グリース組成物に、更にホウ素含有化合物を配合し、前記増ちょう剤としてリチウム石けんを含有することを特徴とする。【選択図】図１
