    摘要： The present invention provides a grease composition for use in constant velocity joints, which comprises the following components (a) to (g) and a constant velocity joint comprising the grease composition sealed or encapsulated therein: (a) a base oil; (b) a diurea thickener represented by the following general formula: R1NH—CO—NH—C6H4-p-CH2—C6H4-p-NH—CO—NHR2 wherein R1 and R2 each independently represents an alkyl group having 8 to 20 carbon atoms, an aryl group having 6 to 12 carbon atoms or a cycloalkyl group having 6 to 12 carbon atoms; (c) a molybdenum dialkyl dithiocarbamate insoluble in the base oil; (d) a molybdenum dialkyl dithiocarbamate soluble in the base oil; (e) molybdenum disulfide; (f) at least one member selected from the group consisting of calcium phenate and calcium sulfonate; and (g) a sulfur-containing extreme-pressure agent free of phosphorus. The grease composition can efficiently prevent a temperature rise of a constant velocity joint and can impart excellent durability to the joint.

    摘要： Provided is a boot for a constant velocity universal joint capable of being properly engaged with an outer joint member of a constant velocity universal joint and capable of increasing durability thereof. Over a shoulder portion (5) and a root portion (13) of a boot (1) for a constant velocity universal joint according to the present invention, there are formed a circular arc portion (14) adjacent to a large diameter portion (2) and having an axial sectional shape protruding radially outward and a linear portion (15) adjacent to the circular arc portion (14) and having a linear axial sectional shape. An innerperipheral surface (16) of the linear portion (15) is brought into contact with an opening end portion (17) of an outer joint member (7) of a constant velocity universal joint (6) such that a thickness from the circular arc portion (14) to the linear portion (15) is uniform.
