Abstract

PROBLEM TO BE SOLVED: To provide the firm threading engagement of an engaging bolt for mounting firmly an annular member by a rotary cylindrical valve body having an opening/closing port and a curable material filling a jacket from a filling port. SOLUTION: When a nozzle body 16 is inserted in a rotary cylindrical valve body 12 and a shutter nozzle 19 is rotated with an operating projection 21, a keying port 15 of the valve body 12 so far closed coincides with a filling port 9 to open the filling port 9. Also, a curable material injection port 18 of a curable material nozzle 17 is adapted to communicate to an opening/closing port 20 of the shutter nozzle 19. Then, the tip of a curable material cylinder is inserted into a curable material nozzle 17 of the nozzle body 16 to infuse the curable material 27 therein with a cylinder pump. Then, the curable material 27 is supplied from the curable material injecting port 18 through ports 20, 15 and filling port 9 into a jacket 8 to enlarge the diameter of the jacket 8. However, since a nut 6 is in front of the injecting port 18 and port 20, the curable material 27 is neither deposited nor affects a fastening operation.
