A male shaft and a female shaft are non-rotatably and slidably fitted to each other and an outer peripheral portion of the male shaft and an inner peripheral portion of the female shaft come in contact with each other to transmit a torque during rotation. A grease composition which has an apparent viscosity of 400 to 750 Pa·s (25° C.) at a shear rate of 10 secas defined in JIS K2220 is enclosed in a gap between the outer peripheral portion of the male shaft and the inner peripheral portion of the female shaft.
