Claims

[Scope of utility model registration request]

3 consisting of an outer ring, an inner upper ring and an inner lower ring disposed inside the outer ring, a main thrust roller and a sub thrust roller that are disposed between the respective rings and move in rolling motion, and a radial direction bearing. In the directional roller bearing, the roller rolling surfaces of the radial direction bearings of the outer ring and the inner ring are formed in a conical shape so as to intersect with a point on the center line of the rotating shaft of the bearing, and the radial roller rolling between them is formed in the conical shape. A three-way roller bearing characterized by having a tapered shape that contacts a rolling surface.
