A roller-type one-way clutch comprising:
an outer race (1) with a pocket (4) with a cam surface (12) formed on an inner surface;
an inner race (2) separated to the radial inside diameter side with respect to the outer race (1), disposed concentrically and relatively rotatable, and having an annular outer peripheral raceway surface (11);
a plurality of rollers (3) disposed on the pocket (4), engaged in the cam surface (12), and transmitting torque between the outer race (1) and the inner race (2);
a cage (6) provided with a cylindrical part (10) and a flange part (17) extending from the cylindrical part (10) to the outside diameter direction, and having a window (18) provided in the cylindrical part (10) and holding the plurality of rollers (3); and
a spring (5) disposed on the pocket (4) one end of which is latched to the outer race (1) the other end of which is held between the roller (3) and the flange part (17) of the cage, and which energizes the roller (3) in the engagement direction with the cam surface (12),
wherein the cage (6) is rotatable relative to the outer race (1) and the circumferential width of the window is smaller than the roller diameter.
