Abstract

PURPOSE:To form a seal bonding part having an appropriate shape at the time and increase the yield in a seal bonding process by applying a weight load to a stem and preventing floating off of the stem from the mount pin. CONSTITUTION:A hollow part 14 which passes to the lower part of an exhaust pipe through hole 9 is formed in a mount pin 7. A cylinder 15 which can be moved up and down is installed inside of the hollow part 14, 16, 16 indicate spring bodies holding elastically the lower part 3a of an exhaust pipe 3, 17 indicates a fixing body to control and fix the pressure of the spring body 16, 18 indicates a rod having down from the fixing body 17. A weight 19 is fixed to the lower end of the rod 18. When the exhaust pipe 3 of a stem 2 is inserted to the exhaust pipe passing hole 9 of the mount pin 7, the lower part 3a of the exhaust pipe 3 is pressed to the spring body 16, and united with the jig mentioned above, and the weight 19 acts so as to bring the stem 2 in contact with the mount pin 7. Therefore, floating off of the stem 2 is prevented. In this state, when a neck glass is heat-bonded with the stem 2, an appropriate seal bonding part 12 can be obtained.
