摘要：<p>A brake-side clutch section on an output side transmits rotational torque input from a lever-side clutch section on an input side, for controlling transmission and interruption of the rotational torque to the output side through lever operation, to the output side, and interrupts rotational torque reversely input from the output side. The brake-side clutch section comprises: a plurality of pairs of cylindrical rollers (27) arranged in wedge gaps (26) formed between a brake-side outer ring (23) restricted in rotation and an output shaft (22) from which the rotational torque is to be output, for controlling the transmission of the input rotational torque and the interruption of the reversely input rotational torque through engagement and disengagement between the brake-side outer ring (23) and the output shaft (22); and plate springs (28) each inserted between each of the plurality of pairs of cylindrical rollers (27), for imparting a repulsive force to the each of the plurality of pairs of cylindrical rollers (27). Each of the plate springs (28) has an N-shape in cross section that comprises an intermediate oblique portion (28a) and upright portions (28b) formed by folding both ends of the intermediate oblique portion (28a) and extending both the ends in opposite directions. An outside dimension between both the ends of the intermediate oblique portion (28a) is set smaller than a maximum gap dimension H2 of each of the wedge gaps (26) formed between the brake-side outer ring (23) and the output shaft (22).</p>
