The branching device (1) includes a cartridge (4) containing a fixed disk and a movable disk, a cover (10) covering the cartridge (4), and an upper end protruding above the cover (10). An operating shaft (5) for sliding the movable disk in the cartridge (4), a lever (6) attached to the upper end of the operating shaft (5), and a mixer (4) between the mixer tap body (2) and the cartridge (4). And a cap nut (12) for connecting the branch block (11) to a tubular external thread (2a) provided at the upper end of the mixer tap body (2).

The cartridge (4) is a known one, and detailed description thereof is omitted. However, as shown in FIG. 3, a water inflow hole (19), a hot water inflow hole (20), and a hot and cold liquid mixture outflow hole ( 21) at the lower end.

The lower end of the cover (10) is provided with a male thread (10a), the lower end of which is slightly above the lower end of the cartridge (4).

The branch block (11) has a substantially columnar shape, and is provided on its outer periphery with two branch pipe connecting tubular male threads (13A) (13B) spaced apart by 180 ° from each other. There. In the branch block (11), as shown in FIG. 3, the passages (7) (8) (9) of the mixer tap body (2) and the corresponding holes (19) (20) of the fixed disk are provided. A water communication passage (14), a hot water communication passage (15), and a hot and cold liquid mixture communication passage (16) are provided to communicate with (21). As shown in FIG. 1, the branch block (11) further communicates the internal passage of each of the tubular male screw portions (13A) (13B) with the water communication passage (14) and the hot water communication passage (15). A water branch passage (17) and a hot water branch passage (18) are provided. The tubular external thread (13A) leading to the water branch passage (17) has, for example, a water purifier pipe for branching water into the water purifier, and the tubular external thread (13B) leading to the hot water branch passage (18) has: For example, a bathtub pipe for branching hot water into the bathtub is connected. Note that the branch pipe connection tubular external thread portions (13A) and (13B) may be any one of them so that only one of water and hot water can be taken out.

At the upper end of the branch block (11), a tubular female thread (11a) is provided in a protruding manner, and this is screwed together with a male thread (10a) provided at the lower end of the cover (10). There. The outer circumference of the tubular female screw portion (11a) is substantially flush with the outer circumference of the cover (10).

A packing (22) is interposed between the lower surface of the cartridge (4) and the upper surface of the branch block (11), and a similar packing (23) is provided on the lower surface of the branch block (11).
