<Item 1>

[0016]

[Means for Solving the Problems] The solution means of the invention taken in order to solve the above-mentioned problems is, "When the cover plate is closed, the connection port is located at a predetermined position of the corresponding cover plate. Has a through hole formed therein, the cap portion is mounted in the through hole so as to be able to move forward and backward with respect to the cover plate, and the cap portion is the most advanced position to the back surface side of the closed cover plate. When it is pushed in until it reaches the end, it is completely attached to the connection port, and unless it is pushed to the most advanced position, the portion continuous to the base end side of the cap portion is outside the surface of the cover plate. It is set so as to project a predetermined height toward one side. "

Since the cap portion is mounted in the through hole provided in the cover plate so as to be able to move back and forth, when the cover plate is closed,
The cap portion comes into contact with the end portion of the connection port of the fluid outlet, and the portion continuous with the base end portion of the cap portion projects from the surface of the cover plate by a predetermined height. Then, this protruding portion is pushed into the back side of the cover plate. When the cap portion is pushed in until it reaches the most advanced position, it is securely attached to each of the connection ports. When the fluid outlet is used (when the protective cap is not used), the cover plate is kept closed and the cap portion is pulled out from the outside of the cover plate to withdraw to the outside, and then the cover plate is opened.

<2> In the invention described in detail in 1 above, “a supporting cylinder capable of advancing and retracting in the front and back direction with respect to the covering plate is attached to the through hole in a retaining state, and the cap portion is , Is accommodated in the support cylinder in a coaxially and entirely enclosed manner. ”, Since the entire cap portion is accommodated in the support cylinder, the seal portion of the cap portion is Since it is housed in the support cylinder, the seal portion is not exposed to the outside when the cap portion is not used.

<3> In the invention described in detail in the above item 2, “the covering plate is of a rotating type, and when the covering plate is opened, the support cylinder and the cap portion do not project to the surface side of the covering plate. As described above, in the case where the support cylinder is attached to the cover plate in a state where it does not come off, the cover plate is rotated in the opening direction about the rotation axis when the hot water outlet is used. In the completely open state, the surface of the cover plate comes into contact with the floor surface or wall surface where the fluid outlet is installed. At this time, since it is set so that the cap portion and the support cylinder do not protrude from the surface of the covering plate,
It is possible to open the surface of the cover plate in such a manner that the entire surface of the cover plate contacts the floor surface or the wall surface without the obstruction of the cap portion and the support cylinder. Further, since the support cylinder is merely fitted in the cover plate so as to be able to move forward and backward and is not fixed, the angle of the support cylinder with respect to the cover plate can be adjusted around the contact portion with the through hole. In the rotatable cover plate, when the cover plate is rotated in the closing direction, the cap portion protruding to the back side of the cover plate is attached to the connection port of the fluid outlet from a diagonally front side. By adjusting the angle of the support cylinder with respect to the cover plate, it becomes easy to make the cap portion face the connection port in the fluid outlet.

<4> In the invention described in detail in the above item 2, “the cover plate is of a slide type so that the support cylinder and the cap portion do not project to the back side of the cover plate when the cover plate is opened. In addition, in the case where the support cylinder is attached to the cover plate in a state where it does not come off, the back surface of the cover plate slides with respect to the surface portion where the opening of the fluid outlet is formed by opening and closing the cover plate. However, since the support cylinder and the cap portion are mounted so as not to project to the back side of the cover plate, even if the cover plate is slid when the cover plate is opened and closed, the support cylinder and the cap portion are not slidable. Does not interfere with sliding. In addition, the support cylinder and the cap portion will not accidentally fall off to the surface side of the cover plate.

<5> In each of the above items 2 to 4, “the pair of cap portions are integrally formed so as to project from the front surface of the connecting member, and the connecting member is
It is composed of a plate-like portion on which the cap portion projects and a tubular body portion that projects rearward from the peripheral edge thereof, and the tubular body portion is set to be slidable in the support cylinder in the advancing / retracting direction. " In this case, since the pair of cap portions are integrally provided on the connecting member and are set to be movable back and forth in the support cylinder together with the connecting member, the pair of cap portions are simultaneously connected by pressing the connecting member. Can be fitted into the mouth.

<6> In the invention described in detail in each of the above items, “a locking mechanism for maintaining a mounted state in which the cap portion is mounted in the connection port in a watertight state, and the cap in the mounted state And a pulling-out means for pulling out the portion are respectively provided. ”, The lock mechanism keeps the cap part completely attached to the connection port, and pulls the pulling-out means to the outside. Thereby, the cap portion can be pulled out from the connection port.

[0023]

As described above, according to the first aspect of the present invention, the cap portion of the protective cap is mounted in the through hole provided in the cover plate so as to be movable back and forth, so that the cap is covered even when the cap is not used. It will remain attached to the board and will not be lost. Therefore, it is not necessary to provide a conventional ball chain, and the structure of the protective cap is simplified correspondingly, the mounting operation is facilitated, and the ball cap can be provided at low cost.
Further, after the covering plate is closed, the cap portion is pressed from the outside of the covering plate to be attached to the connection port of the fluid outlet, so that it is ensured that the attachment of the cap portion is completed one by one. You can check it by hand. Also, unless the cap portion is securely attached to the connection port, the portion continuous with the base end portion projects from the surface of the cover plate by a predetermined height, so that the cap portion is not completely attached to the connection port. It is obvious that there is, and the cap is not left for a long period of time without being attached to the connection port. Therefore, the fluid outlet can be reliably protected when not in use.

In addition to the above effects, in the item (2), since the cap portion is housed in the support cylinder, when the protective cap is not used, the seal portion of the cap portion is stored without being exposed to the outside. Can be set. Therefore, the protection of the cap portion when not in use is ensured.

The item (3) can be applied to a rotary type cover plate.

The item 4 can be applied to a slide type cover plate.

In the case of item 5, the pair of cap portions can be attached to each of the pair of connection ports when both of them are jointly operated by pressing the connecting member to the back side with the cover plate closed. , The mounting work can be done at one time, which is convenient.

[0028] In the item of item 6, when the fluid outlet is not used, a force in the opening direction is applied to the cover plate, or
Even if water pressure is applied from the inside of the connection port, the cap portion does not come off. Therefore, the connection port can be maintained in a state of being reliably protected by the cap portion. Further, when using the fluid outlet, it is easy to remove the cap portion from the connection port by utilizing the drawing means.
