Provided is a rotation transmission device with a built-in one-way clutch capable of reliably locking a one-way clutch over a wide temperature range from a low temperature to a high temperature and achieving a long life of a support bearing. To do. A sleeve that is an inner member, a pulley that is an outer member, a roller clutch that is a one-way clutch, and a support bearing, which is made of ruky diphenyl ether oil or polyol ester oil and has a kinematic viscosity at 100 ° C. of 5 A base oil of ˜15 mm 2 / s is mixed with diurea, which is a reaction product of 4′4-diphenylmethane diisocyanate and cyclohexylamine, as a thickener, and further added with an amine-based antioxidant. The grease composition is lubricated with a grease composition having a consistency of 200 to 230 and an apparent viscosity of 30.4 to 54.8 Pa · s at a shear rate of 200 s −1 at 0 ° C.
