Next, the operation of the water faucet device 1 according to the first embodiment of the present invention described above will be described together with the assembling method and processing method of the water faucet device 1 .
First, according to the water faucet device 1 according to the present embodiment, when assembling the water faucet device 1, the inside of the substantially cylindrical strut portion 8a of the outer shell member 8 formed in a shape corresponding to the type of the water faucet device 1 is A generally cylindrical faucet function unit 18 is inserted against.

Thereby, the base member 16 and the primary side adapter member 50 can be axially connected via the casing member 40 .
In addition, the casing member 40 made of metal allows the axial direction between the base member 16 and the primary side adapter member 50 in the support 8a to correspond to the shape of the outer shell member 8 according to the type of the water faucet device 1. In addition, the strength of the internal structure of the faucet function unit 18 and the like inserted into the strut portion 8a of the outer shell member 8 can be increased.
Further, the metal casing member 40 may be formed in a substantially cylindrical shape by a metal plate or pipe so that it can be inserted into the strut portion 8a of the outer shell member 8 having a shape corresponding to the type of the water faucet device 1. can.
As a result, the casing member 40 can be molded for each shape of the outer shell member 8 according to the type of the water faucet device 1 compared to the case where the casing member 40 is injection-molded with a resin material or the case where the casing member 40 is cast-molded with a metal material. Since there is no need to prepare a mold for the casing member 40, the dimensions and shape of the casing member 40 can be easily adjusted by a relatively inexpensive processing method.
Moreover, since the casing member 40 is formed of a metal plate material or pipe material in a substantially cylindrical shape, the casing member 40 can be formed thin while maintaining necessary strength. Thereby, the internal dimensions of the faucet device 1 can be suppressed.
Furthermore, if a casing member 40 that is made common to some extent is prepared for the outer shell member 8 having various shapes according to the type of the water faucet device 1, the casing member 40 can be relatively cut by cutting or the like. It can be adjusted to a desired axial dimension by an inexpensive machining method. Accordingly, the axial dimension distance of the casing member 40 between the base member 16 and the primary side adapter member 50 can also be freely set according to the axial dimension of the casing member 40 . In addition, the casing member 40 can be easily assembled by simply inserting the casing member 40 with its axial dimension adjusted into the strut portion 8a of the outer shell member 8.

Projection planes S1 to S4 can be formed by projecting onto the vertical plane S0, and the base member 16 and the primary side adapter member 50 are axially (in the direction of the central axis A1) relative to the lower casing member 72. A surface can be formed that can be mechanically engaged with the base member 16 and the primary side adapter member 50 when attempting to move relative to each other.
That is, as shown in FIGS. 10 and 11, the engagement holes 72a and 72b of the lower casing member 72 are projected onto a plane S0 perpendicular to the axial direction of the lower casing member 72 (the direction of the central axis A1). The fact that the projection planes S1 to S4 can be formed by making The engagement holes 72a and 72b of the lower casing member 72 can be mechanically engaged with the base member 16 and the primary side adapter member 50 via the mechanical engagement pins 58 and 60 when an attempt is made to do so. It will also be possible to form a surface for
Therefore, the lower casing member 72 can hold the base member 16 and the primary side adapter member 50 by the engagement holes 72a and 72b of the lower casing member 72 capable of forming such projection planes S1 to S4. become.
As a result, the lower pin engagement holes 72a of the lower casing member 72, the mechanical engagement pins 58 for holding the base member, and the engagement holes 16e of the base member 16 are all arranged so that the lower casing member 72 is mechanically engaged. The joint functions as a mechanical engagement means that enables the base member 16 to be held.
