Abstract:
A tube stock (2'), an interior of which is compartmented into an air chamber (3) and a sealant chamber (7) by a partition (5), is subjected to extruding and cut into a predetermined length, and after an air valve (6) communicating to the air chamber (3) is mounted to the tube stock (2'), both ends of the tube stock (2') is joined by pressure welding to be vulcanized. After a sealant filling hole (41) communicating to the sealant chamber (7) is formed in the tube stock (2'), air is supplied to the air chamber (3) through the air valve (6) to push the partition (5) to expel air from the sealant chamber (7), in which state a sealant (8) is supplied into the sealant chamber (7) through the sealant filling hole (41).
