2. Description of the Related Art When a hot and cold water mixing faucet is attached to a wall panel of a bathroom unit or the like, for example, as shown in FIG. , 54 and the connecting portions 55, 56 of the hot water supply pipe are connected to each other via the pipe connecting adapters 58, 58. The adapter 58,58
Are inserted into the through holes 51A and 51A formed in the wall panel 51, respectively, and the stepped screw cylinder portion 60 located on the indoor side at the time of the insertion and the base portion of the stepped screw cylinder portion 60. It is configured by a flange portion 61 located on the side and having a substantially regular hexagonal shape in plan view, and a screw tubular portion 62 extending from the flange portion 61 to the opposite side of the stepped screw tubular portion 60 and located on the outdoor side. Each adapter 58 is fixed to the wall panel 51 by screwing a nut-shaped stopper 64 into the stepped screw cylinder portion 60 protruding toward the room side from the room side. On this occasion,
A co-rotation preventing member 66 for restricting rotation of the adapters 58, 58 is provided between the flange portions 61, 61 and the wall panel 51.

The co-rotation preventing member 66 is located at a long piece-shaped base portion 68 and both end sides (upper and lower end sides in FIG. 8) in the width direction of the base portion 68, and the outer peripheral edge of the collar portion 61. It is provided with a pair of upper and lower rising portions 69, 69 which are engaged with each other. Through holes 68A are formed in the base portion 68 at three locations along the extending direction thereof.
The stepped screw cylinder portions 60, 60 are inserted into any two of them. Thus, in the state where each adapter 58 is inserted into the through hole 68A, one co-rotation preventing member 66 is held on the wall panel 51 via the two adapters 58, 58, so that the co-rotation preventing member 66 is provided. Can be regulated, and since the outer peripheral edge portion of each flange portion 61 is engaged with the rising portions 69, 69, the relative rotation between each adapter 58 and the co-rotation preventing member 66 can also be regulated. The co-rotation of the adapter 58 is restricted when the stopper 64 is tightened.

[0004]

However, in the co-rotation preventing member 66, the through holes 68A, 68 are formed.
Through holes 51A, 5 of the wall panel 51 that are larger than the maximum separation width of A
If the separation width of 1A is large, two adapters 5
It becomes impossible to attach 8, 58 to one co-rotation preventing member 66. At this time, it is theoretically possible to accommodate one co-rotation preventing member 66, 66 for each adapter 58, 58, but in this case, one co-rotation preventing member 66 for each co-rotation preventing member 66. Since the adapter 58 is supported only by the adapter 58, the adapter 58 and the co-rotation preventing member 66 engaged with the adapter 58 can be integrally rotated, and the adapter 58 can be used together when the stopper 64 is tightened. This causes the inconvenience that it becomes easier to rotate. Therefore, in this case, the work of directly fixing the co-rotation preventing member 66 to the wall panel 11, for example, the work of forming a recess in the wall panel 51 and receiving the co-rotation preventing member 66 in the recess, or the co-rotation prevention The work of screwing or adhering the member 66 to the wall panel 51 is required, which causes an inconvenience that the construction cost rises and the construction becomes complicated.

Here, the co-rotation preventing member includes a base portion attached to the wall panel, and an engagement protrusion provided on one end side of the base portion, and the engagement protrusion is the wall panel. It is possible to employ a configuration in which the fixed portion is contacted with a gap formed between the fixed portion and the fixed portion. Accordingly, even when a step or a bulge is formed at the joint between the fixed portion and the wall panel, the rotation of the adapter can be restricted while avoiding the step or the bulge.

The co-rotation preventing member according to the present invention is a co-rotation preventing member that engages with a pipe connecting adapter inserted into a through hole formed in a wall panel to regulate rotation of the pipe connecting adapter. In the above, a base portion provided along the wall panel and an engaging protrusion provided on one end side of the base portion are provided, and the engaging protrusion is provided on the other end side of another adjacent base portion. It is also possible to adopt a configuration in which they are provided so as to be connectable, and this also makes it possible to achieve the above-mentioned object.

Further, the co-rotation preventing member according to the present invention is a co-rotation preventing member which engages with a pipe connecting adapter inserted into a through hole formed in a wall panel to regulate rotation of the pipe connecting adapter. In the above, the co-rotation preventing member is adjacent to a base portion attached to the wall panel, and an engagement protrusion protruding from one end of the base portion in a direction along the wall panel via a step portion. It is also possible to employ a configuration in which the other end side of the base portion and the engaging projection portion are overlapped with each other, and a restricting means capable of restricting rotation of the engaging projection portion is provided. Accordingly, the rotation of the adapter can be restricted with a relatively simple structure, and the cost of manufacturing the co-rotation preventing member can be reduced.
