PROBLEM TO BE SOLVED: To provide a draft regulation plate not to pass exhaust air through a clearance generated between a drier main body and an exhaustion chamber when inserted. SOLUTION: In this draft regulation plate of the exhaustion chamber in a circulation type grain drier, the circulation type grain drier is provided with a grain drying chamber, and a hot air supply chamber and the exhaustion chamber with the grain drying chamber therebetween, the exhaustion chamber is formed of a frame and a screen, the frame is formed to be removable from the exhaustion chamber, and a ridge-shaped guide plate for guiding a grain is laid in an upper end of the exhaustion chamber. In this draft regulation plate, a resistance plate is provided between the ridge-shaped guide plate and the exhaustion chamber, a plate-like support part is erected on a long support block laid laterally along a longitudinal direction of a frame upper part, and the resistance plate is inclined to be connected to an upper end of the support part, so as to energize an upper end of the resistance plate toward a bottom face of the ridge-shaped guide plate, and so as to direct it toward a clearance formed between the bottom face and the exhaustion chamber.
