摘要： PROBLEM TO BE SOLVED: To provide a valve sealing device facilitating sealing, and small in manufacturing cost.
SOLUTION: A rectangular fitting hole 2 for fitting a rectangular rotary shaft 101 of a valve body 100 thereto is formed at the center of a sealing cover 1 made of a metal thin plate, a sealing band 3 is formed by being extended from one end of the sealing cover 1, and a sealing band fixation part 4 is formed on the opposite side to the sealing band 3. Sealing is carried out by fitting the fitting hole 2 of the sealing cover 1 to the rotary shaft 101, winding a tip side of the sealing band 3 around a neck part 103' of the valve body 100 in a crossing manner, and thereafter inserting the tip side of the sealing band 3 into a fixing hole 4a of the sealing band fixation part 4, thereafter mounting a lead ball 6 to the sealing band 3, and crushing the lead ball 6.
