Claims

[Scope of claim for utility model registration] A rotary valve for a grain dryer having the following requirements. a A plurality of blades for feeding grain that extend radially in the radial direction around the rotation axis. b. A restraining plate that is fixed along the vane plate and whose tip is set back radially inward from the tip of the vane plate. c. An elastic plate that is held between the vane plate and the holding plate, and whose tip protrudes outward in the radial direction beyond the tip of the vane plate. d A curved surface formed by bulging the tip of the elastic plate in the counter-rotational direction when viewed in cross section. e A convex portion formed on the elastic plate at a portion that contacts the tip of the holding plate when the tip of the elastic plate is elastically deformed in the counter-rotational direction.
