PURPOSE:To prevent dirty water and foreign matter from entering a space in a water cock by allowing the uper portion of a cover having a gap from a circumferential face of a recessed portion mentioned below to engage with the upper portion of said recessed portion formed on the back face of a transparent water cock. CONSTITUTION:A screw portion 14 is engaged with a cylindrical portion 2 extruding into a recessed portion 1 of a bushing 8 which is fitted into a handle body A through bonding, ultrasonic welding, high frequency welding or insert forming or the like, thus a first engaging portion 3 is formed. Another screw portion 15 is engaged with a second engagement portion 4 at an edge of a through hole 13 of a cover B engaged with the first engagement portion 3 to combine the portions 3, 4 to each other and the third engagement portion 5 to the fourth engagement portion 6. Consequently, the cover B is fitted into the recessed portion 1 of the handle body A, thus a water cock is formed. |
