Zusammenfassung:	PURPOSE:To maintain a space between bearings, to enable the omission of an inside shield and to aim at prevention of leak of grease and maintenance of a fixed value of torque by projecting the opposite close adhesion side of one side or both sides of the outer ring of two roller bearings from the width between inner rings in an axial direction. CONSTITUTION:A broad portion 1011 projecting in an axial direction is formed at the outer ring 10 of roller bearings 100, 100' opposite side of an outer ring 102 and the inner diameter of the inner circumference 1012 thereof is formed as same as that of the inner circumference 1021 of the outer ring 102. According ly, a gap between the outer rings is eliminated, a leak prevention function of grease is effectively fulfilled to increase a lubricating function, quality control is facilitated, its cost is reduced, in addition, torque can be set at a fixed value.
