PROBLEM TO BE SOLVED: To provide an assembling method of a conical rolling bearing which can prevent a rolling face of the conical roller from being damaged by avoiding the contact of a small flange of an inner ring with the rolling face of the conical roller when assembling the inner ring to a resin-made retainer in a state that the conical roller is temporarily inserted into the retainer, and the conical rolling bearing.SOLUTION: At the assembling, an annular jig 20 is attached to the axial end face of the small flange 12c of the inner ring 12a, the outside diameter face 20a of the jig 20 is formed into a tapered shape, an angle α1 of the outside diameter face 20a of the jig 20 is set smaller than an angle &bgr; at the inside diameter side of the conical roller 14 in a state of being held at a pocket 14d, a small outside diameter D3 of the jig 20 is set smaller than an internally-contacting circular diameter D2 of the conical roller 13, and a large outside diameter D4 of the jig 20 is set larger than an outside diameter D5 of the end face of the small flange 12c. |
