    Abstract: A valve unit includes a rotary valve having a predetermined clearance between an inner surface of a main body and a valve element. The magnet coupling includes eight outer peripheral magnets and eight inner peripheral magnets having N-poles and S-poles each on an outer or inner peripheral side. The outer peripheral magnets are disposed such that the N-poles and the S-poles are disposed alternately in a circumferential direction and such that a distance between the central axis and an outer peripheral surface of the outer peripheral magnets is between 90% and 100% of a distance between the central axis and an outer surface of the main body closest to the central axis in a direction perpendicular to the central axis. The inner peripheral magnets are disposed opposite to the outer peripheral magnets such that the N-poles and the S-poles are disposed alternately in the circumferential direction.
