权利要求: 1. Use of a grease composition to increase the friction of a lubricated part of a power transmission device, characterised in that the grease composition comprises: a silicone oil (A) and zinc dialkyldithiocarbamate (B); and a content of zinc dialkyldithiophosphate (BX) of 0.01 mass% or less relative to the total amount of the composition.2. The use according to claim 1, wherein a content of the zinc dialkyldithiocarbamate (B) is from 7.5 mass% to 20 mass % relative to the total amount of the composition.3. The use according to claim 1, wherein a content of the zinc dialkyldithiocarbamate (B) is from 5 mass% to 30 mass% relative to the total amount of the composition.4. The use according to any one of claims 1 to 3, further comprising at least one type of thickener (C) selected from the group consisting of lithium soap and lithium complex soap.5. The use according to any one of claims 1 to 4, wherein a content of the silicone oil (A) is in a range of 50 mass% to 95 mass% relative to the total amount of the composition, and the silicone oil (A) has an aromatic hydrocarbon group per molecule.6. The use as claimed in any one of claims 1 to 5, wherein the power transmission device is a clutch or a torque limiter mechanism.7. The use as claimed in claim 6, wherein the power transmission device is a clutch cam chamber formed by an outer clutch and an inner clutch.
