[Problems to be solved by the device]

 In addition to the difference in the coefficient of thermal expansion between the resin-made display and the metal cover, the conventional display described above has a thin metal cover, and the depth of the recessed hole is not sufficient, so that the resin and metal If the resin cover and the metal cover expand with their respective coefficients of thermal expansion due to repeated contact with the metal cover due to the reduced contact area with the cover, etc. There was a risk that the display would peel off and fall off the metal cover during cleaning, etc. due to the reduced force.

In order to solve this, it may be considered that the recessed hole is formed in a groove shape to prevent the resin display body from falling off. However, in that case, the hole processing for forming the recessed hole becomes complicated, and the display becomes difficult. There is a problem that the formation of the body is troublesome. The present invention has been made in view of the above conventional circumstances, and an object thereof is to prevent the display body from being expanded even if the resin display body and the metal cover expand with their respective thermal expansion coefficients during use. Delamination. It is to provide a display for a faucet that is unlikely to fall off.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, a display for a faucet according to the present invention is provided with a recessed hole bottom wall provided on a metal cover surface of a faucet main body. The through hole reaching the back surface is opened, and the display body that fits into the recess and the locking plug that projects and engages with the back surface of the cover through the through hole are integrally formed. Characterize.

For the reason described below, the main body of the display body is molded with a liquid resin that fills and cures in the concave hole, and the liquid resin that flows into the through hole and swells to the back surface of the cover is locked. It is effective to form the stopper integrally with the display body.

[0007]

[Action]

 According to the first aspect of the present invention, if the display body is fitted into the recessed hole by pushing the lock plug into the through hole, the lock plug protrudes and engages with the back surface of the cover, and the lock plug and the display body. With the bottom wall of the recessed hole sandwiched between and, the display body is attached to the metal cover in a locking manner. Therefore, even if the resin display body and the metal cover expand with their respective coefficients of thermal expansion and the display body body is loosely fitted into the recessed hole, the display body body is separated due to the locking action of the locking plug. -It can be prevented from falling off.

According to the second aspect, by dropping the liquid resin into the concave hole provided on the surface of the cover, the resin material is filled in the concave hole and the through hole, and the surface tension of the resin material itself is applied. The liquid resin hardens in a state where it swells slightly to the back side of the cover, thereby forming the main body of the display in the recessed hole, and at the same time, the stopper plug that protrudes and engages with the back side of the cover through the through hole is displayed. It is formed continuously and integrally with the body. Therefore, in addition to the function of preventing the display body main body from peeling off and falling off according to the first aspect, the display body main body and the locking plug can be molded and mounted on the metal cover at the same time.
