Abstract: A rolling bearing for a rocker arm includes an outer ring in rolling contact with a cam of an engine, an outer-ring shaft placed inside the outer ring and fixed to the rocker arm, and a plurality of rollers provided between the outer ring and the outer-ring shaft. At least one of the outer ring, the outer-ring shaft and the rolling elements has a nitrogen-rich layer, an austenite crystal grain size number in a range exceeding 10, and a surface hardness Hv of at least 653. Thus, the life can be extended.

Abstract: An outer ring for rocking bearing (11a) includes a raceway surface (12a) on the inner diameter side and has flange parts (13a) and (13b) provided by bending both axial ends to the inner diameter side. The flange parts (13a) and (13b) are provided with bent parts (17a) and (17b) axially bent toward the raceway surface (12a) side so as to enfold a retainer arranged on the inner diameter side. Thus, the retainer can be enfolded by the bent parts (17a) and (17b). Therefore, even when the retainer comes to be moved to the inner diameter side of the outer ring for rocking bearing (11a), the retainer is caught by the bent parts (17a) and (17b), so that the movement of the retainer to the inner diameter side is restricted and rollers and the retainer can be prevented from dropping off.

Abstract translation: 用于摆动轴承（11a）的外圈包括内径侧的滚道表面（12a），并且具有通过将两个轴向端部弯曲到内径侧而设置的凸缘部（13a）和（13b）。 凸缘部（13a）和（13b）设置有朝向滚道表面（12a）侧轴向弯曲的弯曲部分（17a）和（17b），以覆盖设置在内径侧的保持架。 因此，保持器能够被弯曲部分（17a）和（17b）包住。 因此，即使当保持器移动到用于摆动轴承（11a）的外圈的内径侧时，保持器被弯曲部（17a）和（17b）卡住，使得保持器的移动 内径侧被限制，并且可以防止辊和保持器脱落。
