The present invention relates to a one-way clutch which includes multiple electric pieces mounted between an outer race and an inner race, and a lever which is installed to be caught in the electric pieces and the inner race and, more specifically, to a lever-type one-way clutch, when idling without connecting power between the inner race and the outer race, which maintains a fixed gap between the inner circumference of the outer race and the outer circumference of the electric pieces and prevents friction, thereby extending the lifespan of the clutch, miniaturizing the clutch, and improving the performance of the clutch. The lever-type one-way clutch according to the present invention includes the following components: an outer race (20); an inner race (10) which is installed to be relatively rotated to the outer race (20); multiple electric pieces (30) which are installed inside of the outer race (20) and connect or disconnect power between the outer race (20) and the inner race (10); and a lever (40) which is installed in a way that one end is caught by the inner race (10) and the other end is caught between the electric pieces (30). The lever-type one-way clutch delivers power in a direction by increasing the diameter of the electric pieces (30) through the leverage of the lever (40), and additionally includes a gap switching unit (60) which maintains a fixed gap between the multiple electric pieces (30) and the outer race (20) when power is disconnected between the outer race (20) and the inner race (10), and presses the multiple electric pieces (30) to the outer race (20) when power is connected. |
