<p>Disclosed is power transmission equipment which can switch transmission and interruption of rotation in a fixed direction quickly while preventing impact at the time of switching, and can prevent reduction in the amount of output during inertial motion without requiring an extra control. Since transmission and interruption of rotation in a fixed direction are switched by tilting a first sprag (13), the time required for switching can be shortened and switching can be carried out quickly. Furthermore, since the first inner ring (11) and the first outer ring (12) do not idle during the interval between a state of not transmitting power and a state of transmitting power, impact can be prevented at the time of switching. Furthermore, since the first sprag (13) tilts naturally in the anti-self lock direction during inertial motion, braking can be prevented during inertial motion and reduction in the amount of output can be prevented during inertial motion.</p> |
