てしまう。2. Description of the Related Art There is a dedicated nozzle which is attached to a water supply hose to form a shower. This consists of a grip part following the hose connection part, a head part equipped with a shower plate, and a flow path opening / closing means for opening and closing the flow path at hand, and with a mechanism for switching the jet water flow. There is also. If water is stopped by the flow path opening and closing means after use of such a nozzle, water in the nozzle remains without being completely discharged.

発明の目的は、ノズル内に残った水が凍っても、ノズル
本体が破裂しないようにすることである。Therefore, in cold regions, the water inside the nozzle freezes and its volume increases, so that the nozzle body may be ruptured. Therefore, an object of the present invention is to prevent the nozzle main body from bursting even when water remaining in the nozzle freezes.

体の破裂を防止する。The water left in the nozzle starts to freeze, particularly in the details inside the flow path downstream of the flow path opening / closing means, and the volume expands.
At this time, the inside of the freezing absorber deforms and absorbs a rise in pressure due to the volume expansion of water, thereby preventing the nozzle body from bursting.

It is. The head portion 2 is surrounded by a head cover 9 and a shower plate 4, and the internal cylinder 3 is connected to the cover 9 with screws, so that the cover 9 moves back and forth by rotation. And on the downstream side of the cock 5,
A sponge-shaped rubber freezing absorber 10 is installed and held by an absorber stopper 11. 6 is a cap slide valve cylinder, 7 is an O-ring cup, 8

When the head cover 9 is rotated and moved forward, first, the channel B opens and communicates with the channel A.
→ Spouts out as a straight stream through channel B.
Further, the head cover 9 is rotated to move forward,
When the flow path A coincides with the flow path C, the water flow becomes the flow path A → the flow path C → the flow path D → the shower plate 4 and becomes a shower.

に、自由である。As described above, when the cock 5 is closed after use, water remains inside the head portion 2. In particular, the water in the cylinder 3 hardly comes off, and the water freezes.
When the temperature of the outside falls, little by little from the part close to the outside air,
As it begins to freeze, the volume expands. As the volume expands, the internal pressure increases. The increased pressure deforms the freeze absorber 10, so that the nozzle body can be prevented from bursting. In this embodiment, a cock is used as the passage opening / closing means, but the invention is not limited to this. In addition, as shown in FIG.
Although it is a semi-cylindrical type and is provided adjacent to the cock insertion portion 18, both the shape and the installation position are free as long as the flow of water is not obstructed.
