Has been done. In such a structure, if it is going to obtain sufficient watertightness, smooth rotation operability will be inhibited, and if it is intended to obtain smooth rotation operability, sufficient watertightness will be inhibited. Therefore, in this example, the seal member 72 having a bag-like portion that is in close contact with a member that achieves water tightness when subjected to fluid pressure, for example, a seal member 72 such as an X packing, a U packing, a V packing, and the like is different in form. In addition, an elastic member 73 such as an O-ring or a plate-like packing is interposed between the water discharge port 70 and the mounting portion 21 to prevent rattling between the members that are appropriately elastically deformed and rotated. In such a structure, sufficient water tightness is ensured by the seal member 72, and sufficient rotation operability is ensured by the elastic member 73.
[0030]
In this example, the elastic member 73 is disposed on the back side of the insertion portion of the members to be inserted into each other to further prevent rattling. In addition, a member having a sealing function is adopted as the elastic member 73, and the water tightness is further improved with the sealing member 72. Here, by disposing the elastic member 73 on the back side of the insertion portion, the elastic member 73 functions as a primary seal member, and the seal member 72 having more excellent watertightness is the secondary seal. Functions as a member. Therefore, even if water leaks from the elastic member 73 as the primary seal member, the water leak is reliably sealed by the secondary seal member 72. Thereby, reliability can be improved.
