- p is 0 or 1.
- [7] The description according to any one of [1] to [6] above, wherein the content of the component (B) is 0.01 to 3.0% by mass based on the total amount of the lubricating oil composition.
- Lubricating oil composition [8] The description according to any one of [1] to [6] above, wherein the content of the component (B) is 0.10 to 1.0% by mass based on the total amount of the lubricating oil composition.
- Lubricating oil composition The description according to any one of [1] to [6] above, wherein the content of the component (B) is 0.10 to 1.0% by mass based on the total amount of the lubricating oil composition.
- the component (C) contains one or more sulfur phosphorus-based compounds (C1) selected from a sulfur atom-containing phosphoric acid ester and a sulfur atom-containing subphosphate ester. thing.
- the lubricating oil composition of one preferred embodiment of the present invention is a lubricating oil composition having properties suitable for various mechanisms incorporated in the apparatus, and the lubricating oil composition of a more preferred embodiment is cooling property. It is possible to improve scuffing resistance and insulation in a well-balanced manner. Therefore, these lubricating oil compositions can be suitably used for lubrication of speed reducers and the like.
- the upper limit value and the lower limit value can be arbitrarily combined.
- the numerical range is described as “preferably 30 to 100, more preferably 40 to 80”
- the range of "30 to 80” and the range of "40 to 100” are also described in the present specification. It is included in the numerical range.
- the numerical range is described as "preferably 30 or more, more preferably 40 or more, preferably 100 or less, more preferably 80 or less”
- the range and the range of "40-100” are also included in the numerical range described herein.
- the description of "60 to 100” means that the range is "60 or more and 100 or less”.
