A seat retainer that is slidable in the axial direction of the valve is provided in the seal between the valve body and the ball, and the seat portion of a seat ring provided at the tip of the seat retainer is pressed against the ball. In a ball valve that prevents leakage, an annular groove is bored in the side surface of the seat retainer opposite to the ball, a wiper that can slide freely against the groove is placed in the groove, and the wiper is pushed against the ball surface. A 'ball valve seal structure' characterized by being equipped with a compressing elastic member. 2. The seal structure described in claim 1 of the utility model registration, in which the wiper is made of metal. 3. The seal structure described in claim 1 of the utility model registration claim, in which the elastic member has a U-shaped or ■-shaped cross section. 4. The seal structure according to claim 1 of the utility model registration, in which the contact portion with the wiper ball surface is formed at an acute angle. 1 5 Utility model registration in which the seat retainer has a threaded part that opens toward the groove, and the wiper has a hole for inserting the tip of a set bolt screwed into the threaded part. A seal structure according to claim 1.
