PCT No. PCT/JP96/00231 Sec. 371 Date Feb. 13, 1997 Sec. 102(e) Date Feb. 13, 1997 PCT Filed Feb. 5, 1996 PCT Pub. No. WO96/24778 PCT Pub. Date Aug. 15, 1996The present invention discloses a roller and cage assembly that inhibits generation of heat and in turn, prevents the occurrence of seizure, thereby attaining a long service life while also offering various other advantages. By cutting away the outside of a cage (1) in order to completely remove indentations (1j) formed during machining of outer retaining projections, the outer surface of those outer retaining projections (1h1) is made to coincide with the normal diameter (D0) of the cage (1). As a result of employing this constitution, even if the roller guide surfaces of the columns (1c) of the cage (1) become worn, the rollers (2) do not make contact with the outer retaining projections (1h1). In addition, since the above-mentioned indentations do not remain, the contact surface area with an attaching partner is increased, thereby reducing contact pressure, thereby allowing the object described above to be attained.
