A roller bearing (5) includes: an outer ring (13) that has outer ring raceway surfaces (13b1, 13b2); an inner ring (12) that has inner ring raceway surfaces (12b1, 12b2) that face the outer ring raceway surfaces (13b); a plurality of cylindrical rollers (141, 142) that are arranged between the outer ring raceway surfaces (13b) and the inner ring raceway surfaces (12b). The outer ring (13) has an outer ring rib (13a) that is in point-contact with one axial end surface of each of the cylindrical rollers (141, 142) and that is arranged adjacent to the outer ring raceway surfaces (13b). Contact positions (Po) at which the cylindrical rollers (141, 142) contact the outer ring rib (13a) are set to be on an axis (O1) of the cylindrical roller (141) and an axis (02) of the cylindrical roller (142).
