Abstract
Provided is a centrifugal field-flow fractionation device that can stably press a fixing member toward an inner peripheral surface of a rotor by a wedge-shaped member, even when a relatively large centrifugal force acts on the wedge-shaped member. An arc-shaped (C-shaped) fixing memberis provided along an inner peripheral surface of a channel memberon a side of a rotation axis of the channel member. A wedge-shaped memberis attached between opposite ends of the fixing memberand applies a force in a direction of spreading the opposite ends apart, to thereby press the fixing membertoward the inner peripheral surface of the rotor. The wedge-shaped memberhas a pair of contact surfacesthat respectively come into contact with the opposite ends of the fixing member. The pair of contact surfacesinclude tapered surfaces that gradually taper down toward the rotor, so that the distance between the contact surfacesgradually shortens as the contact surfacescome close to the rotor
