  However, the conventional showerhead connecting twist preventing device has the following problems.

  First, when water pressure is applied, the water will collect in the center of the U-shaped watertight packing, and the lower end inside the watertight packing will be pushed strongly, and the frictional force with the packing fixing piece of the hose connection stand Increases, and this part cannot rotate freely, so that the metal hose becomes twisted.

  Second, the sealing fixture surrounds the entire periphery of the upper end of the hose connection base, and a separate fixed sealing ring is required at this part, which complicates the product and conversely prevents rotation. become unable.

In order to solve the above-mentioned problems, the present invention relates to a connector included in a connector formed with a lower end fixed stepped jaw in which a lower end fixed portion on which the upper end peripheral portion of a hose is mounted is screwed to a lower end of a shower device.
A lower end main body to be inserted into the inner peripheral edge of the hose, a main body flange formed at the upper end of the lower end main body to be protruded from the peripheral edge portion, and a coupling main body formed at the upper end of the main body flange with an upper end main body;
A donut-shaped token made of a thin metal plate which is placed on the upper end of the main body flange and has a center inserted into a peripheral portion of the upper end main body in the center,
A packing that is placed on the upper end of the token and has a U-shaped ring shape whose cross-sectional shape is open upward,
The upper end of the upper end body of the connecting member main body is fixed to a peripheral edge of the upper end, and is fixed by a main body upper fixing member made of a thin plate of a synthetic resin material.

  The metal hose showerhead connector of the present invention produces the following effects.

  First, the packing is formed so as to make line contact on both sides of the upper end.When pressure is applied, the frictional force between the outer wall of the upper end body and the inner wall of the coupling is minimized, and the lower end is rubbed with the token. However, the low coefficient of friction of the token prevents the hose from rotating as a whole, and the shower and the coupling are easily rotated, so that the hose is not twisted.

  Secondly, the watertightness is perfected by one packing, so no separate packing is required and the product is simplified.
