PROBLEM TO BE SOLVED: To solve the problem that if a rim wall face is provided in the vertical direction of the rim to shield a rim water discharging nozzle so that it can not be seen by a user, since it tends to interfere with the rim wall face when the rim water discharging nozzle is installed inside a narrow rim water passage, it takes much time for fixing work. SOLUTION: The rear end 1a of the rim water discharging nozzle is directed upward after a rubber packing 18 is set in a rim hole 8, while bringing the tip 1b of the rim water discharging nozzle into contact with the inside 15a of the rim wall face, a telescopic part 16 is contracted, and the rim water discharging nozzle 1 is inserted into the rim 4. After that, the rim water discharging nozzle 1a is drawn out until a contacting part 21 comes into contact with the rubber packing 18 and fixed with a nut 19.
