However, in the above-mentioned conventional faucet device, since the casing member inserted inside the outer shell member is made of a resin material, the size and shape of the outer shell member can be adjusted according to the type of the faucet device. Therefore, it is necessary to prepare a mold for injection molding, and there is a problem that the manufacturing cost is high.
Further, the resin casing member of the conventional faucet device has a problem that the strength is lower than that of the metal casing member and the durability due to aging or the like is also low. As a result, in order to ensure long-term safety, there is a problem that maintenance such as inspection and parts replacement is costly.

On the other hand, if the casing member of a conventional faucet device is cast using a metal such as a copper alloy different from the resin material, it is necessary to take measures to regulate the elution of the lead component from the copper alloy. There is also a problem that the size of the casing member itself becomes large, or that it is easily affected by fluctuations in the copper price.
Further, in consideration of the circumstances of the faucet device that is constantly exposed to hot water, when a stainless steel material having high corrosion resistance is used as the casing member, there is a problem that it is difficult to process the stainless steel material with high processing accuracy.
Therefore, we have realized decopper alloys and decasts, utilized materials other than copper alloys, and have a degree of freedom in design while suppressing manufacturing costs for various specifications depending on the type of faucet device. How to raise it has become an issue that has been requested in recent years.

Further, in the case where the spout side flow path forming member is provided in the spout portion of the outer shell member in order to give the spout portion various functions, the outer shell member has conventionally supported the spout side flow path forming member. However, when water pressure is applied to the spout side flow path forming member, a force that tries to escape to the spout side due to the water pressure acts. Therefore, in order to counter the force, the outer shell member needs to have a certain strength.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art and the problems requested in recent years, and can improve the degree of freedom in design and suppress the manufacturing cost. It is an object of the present invention to provide a method for manufacturing a plug device.
Further, the present invention is a faucet device and a method for manufacturing the faucet device, which can reduce the strength required for the outer shell member by releasing (at least a part of) the support of the spout side flow path forming member from the outer shell member. Is intended to provide.

In order to solve the above-mentioned problems, the present invention is a faucet device capable of discharging and stopping hot water obtained by mixing hot water supplied from a hot water supply source and water supplied from a water supply source. A pedestal member fixed to the installation surface on which the device is installed, a substantially tubular strut portion formed in a shape corresponding to the type of the faucet device and attached to the pedestal member, and a side surface of the strut portion. An outer shell member provided with a spout portion, a metal casing member inserted into a strut portion of the outer shell member, and one end side thereof being fixed to the pedestal member, and a metal casing member provided inside the casing member. A hot water supply flow path and a water supply flow path that extend downstream from the pedestal member to form a primary side flow path for supplying hot water and water, respectively, and a single provided inside the other end side of the casing member. A lever cartridge, an on-off valve that adjusts the mixing ratio and flow rate of the hot water supply flow path and hot water supplied from the water supply flow path, and a single lever that enables opening and closing operations of the on-off valve. The single lever cartridge provided with the above, a connecting member provided inside the casing member and connecting the downstream ends of the hot water supply flow path and the water supply flow path to the single lever cartridge, and the single lever. It has a fixing member for fixing the cartridge to the connecting member and a spout side flow path forming member for forming a spout flow path extending to the water spout in the spout portion, and the casing member is the outer shell member. It is formed of a metal plate material or pipe material with dimensions that can be inserted into the support column, and a secondary side adapter member is provided between the casing member and the outer shell member, and the secondary side adapter member is The water faucet device is supported by the casing member, and the spout side flow path forming member is fixed by the secondary adapter member.

In the present invention configured as described above, when assembling the faucet device, the inside of the substantially tubular strut portion of the outer shell member formed in a shape corresponding to the type of the faucet device is generally at least semi-cylindrical. The metal casing member of the above is inserted. At that time, the metal casing member can be used to determine the axial space and distance dimension in the strut portion according to the shape of the outer shell member according to the type of the faucet device, and also in the support portion. The strength of the inserted internal structure can be increased.
Further, the metal casing member can be formed into a substantially semi-cylindrical shape by a metal plate material or a pipe material so as to be inserted into a support column of an outer shell member having a shape corresponding to the type of the faucet device. As a result, compared to the case where the casing member is injection-molded with a resin material or cast-molded with a metal material, a mold for molding the casing member can be formed for each shape of the outer shell member according to the type of the faucet device. Since it is not necessary to prepare the casing member, the dimensions and shape of the casing member can be easily adjusted by a relatively inexpensive processing method.
Further, since the casing member is formed of a metal plate or pipe material in a substantially semi-cylindrical shape, the casing member can be formed thin while maintaining the required strength. As a result, the internal dimensions of the faucet device can be suppressed.
Furthermore, if a casing member that has been made common to some extent is prepared for the outer shell members having various shapes according to the type of the faucet device, it is only necessary to perform cutting or the like on a part of the casing member. It can be adjusted to a desired axial dimension by a relatively inexpensive processing method. Thereby, for example, the axial dimensional distance of the casing member between the pedestal member and the connecting member can be freely set according to the axial dimension of the casing member. Further, the casing member having its axial dimensions adjusted can be easily assembled by simply inserting it into the support column of the outer shell member.
As a result, the degree of freedom in designing the faucet device can be improved, and the manufacturing cost can be suppressed.

Further, according to the present invention, a secondary side adapter member is provided between the casing member and the outer shell member, the secondary side adapter member is supported by the casing member, and the spout side flow path forming member is It is fixed by the secondary side adapter member. As a result, the spout side flow path forming member is supported by the casing member via the secondary side adapter member. Therefore, the support (at least a part of) of the spout side flow path forming member can be released from the outer shell member, and the strength required for the outer shell member can be reduced.

In the present invention, preferably, the secondary side adapter member is watertightly supported by the casing member, and hot water flowing out from the single lever cartridge is spouted between the casing member and the secondary side adapter member. A secondary side flow path that flows to the spout flow path of the side flow path forming member is formed.
According to this, the secondary side adapter member can be effectively supported by the casing member. In addition, it is easy to design the secondary side adapter member to be small (thin), and it does not hinder the miniaturization of the faucet device.

Further, in the present invention, preferably, the end portion of the spout side flow path forming member on the secondary side adapter member side is provided on the secondary side adapter member via a seal member such as an O-ring. It is inserted into the opening and fixed.
According to this, the spout side flow path forming member can be effectively supported by the secondary side adapter member.
Further, in this case, a protrusion is provided on the outer peripheral surface of the spout side flow path forming member in the vicinity of the end portion of the spout side flow path forming member on the secondary side adapter member side, and the protrusion is discharged. It is more preferable that the locking member that prevents the spout side flow path forming member from coming out of the secondary side adapter member by locking the surface on the water port side is supported by the secondary side adapter member. ..
According to this, it is possible to effectively prevent the spout side flow path forming member from coming out of the secondary side adapter member. Further, since the locking member is supported (for example, fixed) by the secondary side adapter member, the force at the time of locking is also supported by the casing member via the secondary side adapter member, which is undesired for the outer shell member. No load is generated.

The protrusion may be provided, for example, in a flange shape.
The locking member may be composed of, for example, a tubular member provided with a fitting groove or a wall-shaped member having an arc-shaped cross section (for example, a C-shaped cross section), and the fitting groove is a flow path on the spout side. It may be formed in a shape or size that allows fitting of a portion adjacent to the spout side with respect to the protruding portion of the forming member, but does not allow passage of the protruding portion.
Further, the locking member is made of metal, for example, in order to ensure sufficient strength.
On the other hand, the secondary side adapter member and the spout side flow path forming member are usually made of resin.

Further, in the present invention, preferably, a rib portion is provided on the outer peripheral surface on the lower side of the spout side flow path forming member in the vicinity of the end portion on the secondary side adapter member side of the spout side flow path forming member. The rib portion extends toward the end portion of the spout side flow path forming member on the secondary side adapter member side and is in contact with the secondary side adapter member.
According to this, the rib portion that comes into contact with the secondary side adapter member functions like a "replacement rod", and the spout side flow path forming member bends downward ("bows") on the spout side. Can be effectively suppressed.

According to the faucet device of the present invention and the manufacturing method thereof, the degree of freedom in design can be improved and the manufacturing cost can be suppressed.
