Claims

[Scope of Claim for Utility Model Registration] 1. Ayu fishing boat having a fish input port on the top surface of a hollow towing boat body, and an inlet and a water drain port in the front and rear walls of the towing boat body, respectively. In the towing boat, a plug seat portion whose vertical surface projects outward in a semicircular arc shape is formed at the water drain port portion of the rear wall portion, and the plug seat portion communicates with the water drain port. A drain hole is formed, and bearings are formed at both ends of the stopper seat, and the stopper has a rotating shaft that is rotatably and slidably fitted into the bearings. A circular arc portion is formed in contact with the inner surface while maintaining a watertight state, a through hole that can match the water drain hole is bored, and a weight body is provided on the side of the circular arc portion in a direction perpendicular to the through hole. A water drain plug for a towing boat for sweetfish fishing, characterized by comprising: 2. Claim 1, characterized in that a buoyancy body is provided at a portion facing the weight body with respect to the rotation axis of the plug body.
Drain stopper for the ayu fishing towboat described.
