On the inner peripheral surface of the second engaging portion 11, a second protrusion 11a extending in the width direction of the second arm 3 is formed.

A second guide wall 11b protrudes along the extending direction of the second arm 3 on the side of one side edge in the width direction (the side edge on the front side of the sheet of FIG. 1) in the second engaging portion 11. . An arc-shaped second locking rib 23 is provided along the extending direction of the second arm 3 at one side edge in the width direction on the inner peripheral surface of the second arm 3, and the second locking The rib 23 is continued to the second guide wall 11b. A second contact portion 24 is provided on the outer surface of the second guide wall 11 b so as to face the first contact portion 22 of the first arm 2.

An intermediate portion between the first hinge portion 7a and the second end 2b of the first arm 2 and an intermediate portion between the second hinge portion 8a and the fourth end 3b of the second arm 3 are spring members. It is linked by twelve. The spring member 12 is formed of an arc-shaped leaf spring which is integrally formed with the base 1 or the like and is convex toward the plate 5 side.

In the holder 101 in the state shown in FIG. 2, the first arm 2 and the second arm 3 are brought into the states shown in FIGS. That is, in the holder 101 in the state shown in FIG. 2, a portion in the vicinity of the neck portion 56 (see FIG. 8) in the water stop valve 102 is disposed between the first arm 2 and the second arm 3.

In this state, by pressing the water stop valve 102 on the second end 2b side of the first arm 2 and the fourth end 3b side of the second arm 3, the first arm 2 takes the first hinge portion 7a as a fulcrum. Also, the second arm 3 tilts with the second hinge portion 8a as a fulcrum. At this time, it is also possible to assist tilting of the first arm 2 and the second arm 3 using the first finger hook unit 10 and the second finger hook unit 13.

Therefore, as shown in FIGS. 6 and 8, the first end 2a of the first arm 2 and the third end 3a of the second arm 3 approach each other, and eventually the first protrusion of the first engagement portion 9 9a and the second projection 11a of the second engagement portion 11 are snap-engaged to hold the water stop valve 102 between the first arm 2 and the second arm 3.

When the first arm 2 and the second arm 3 are tilted during the operation of holding the water stop valve 102 in the holder 101, the spring material 12 is elastically deformed to generate a reaction force in the direction that prevents the tilting. The reaction force acts in a direction to strengthen the meshing between the first protrusion 9 a of the first engagement portion 9 and the second protrusion 11 a of the second engagement portion 11, and thus the first engagement portion 9 and the second engagement portion The engagement with the engagement portion 11, that is, the clamping of the water stop valve 102 is ensured.

And when the said water stop valve 102 is strongly pressed with respect to the 1st arm 2 and the 2nd arm 3 in the case of the said operation | work, in the 1st arm 2, the 2nd end 2b side rather than the 1st hinge part 7a. And the portion on the fourth end 3b side of the second arm 3 more than the second hinge portion 8a in the second arm 3, and the second end 2b of the first arm 2 and the fourth end 3b of the second arm 3 The interval between the two or more tends to expand excessively in part or all.

However, the spring member 12 is a portion of the first arm 2 closer to the second end 2b than the first hinge 7a, and a portion of the second arm 3 closer to the fourth end 3b than the second hinge 8a. Restraint. For this reason, it can suppress that the space | interval of the 2nd end 2b of the 1st arm 2 and the 4th end 3b of the 2nd arm 3 expands excessively, and holding the water stop valve 102 stably in a predetermined position is possible. It becomes possible.

Now, FIG. 6 and FIG. 8 and FIG.
As shown in FIG. 6, when holding the water stop valve 102 in the holder 101, the first locking rib 21 and the first contact portion 22 of the first arm 2 with respect to the neck portion 56 of the water stop valve 102. And the second contact rib 24 of the second arm 3 and the second contact portion 24 face the contact portion 54a of the water stop valve 102 with the first contact portion 22 and the second contact portion 24. The water stop valve 102 is disposed between the first arm 2 and the second arm 3 so as to be located between the abutments 24.

In this state, when the first arm 2 and the second arm 3 are tilted, the first engagement rib 21 and the second engagement rib 23 are positioned on substantially the same circle, and the first engagement is performed. The stop rib 21 and the second locking rib 23 and the step 52 a of the first pipe joint 52 face each other in the front and back direction in the direction along the pipe axis L. Further, as the first arm 2 and the second arm 3 tilt, the first contact portion 22 and the second contact portion 24 come close to each other, and the first contact portion 22 and the second contact portion 24 move. The abutted portion 54a of the water stop valve 102 is sandwiched between the two.

Therefore, when the step 52 a of the water stop valve 102 abuts on the first engagement rib 21 and the second engagement rib 23 of the holder 101, the water stop valve 102 extends along the tube axis L with respect to the holder 101. Movement in the first direction (upward in FIG. 8) is restricted. Further, in the water stop valve 102, the outer peripheral surface of the operation portion 55 in the water stop valve 102 abuts on the first contact portion 22 and the second contact portion 24 of the holder 101, whereby the tube axis relative to the holder 101 is obtained. Movement in the second direction (downward in FIG. 8) opposite to the first direction along L is restricted.

In the water stop valve 102, the abutted portion 54 a of the water stop valve 102 abuts on the first contact portion 22 of the holder 101 so that the first direction centering on the pipe axis L with respect to the holder 101 is obtained. Rotation is restricted. In addition, the water stop valve 102 is configured such that the abutted portion 54 a of the water stop valve 102 abuts on the second contact portion 24 of the holder 101, thereby centering on the pipe axis L with respect to the holder 101. The rotation in the second direction opposite to the direction is restricted.

As described above, since the holder 101 can keep the posture of the held water stop valve 102 constant, for example, even if an external force is applied to the water stop valve 102, the external force is not limited to the pipes 103, 104, etc. Can be prevented from being propagated to the other piping members to twist, bend, or tension the other piping members. In addition, even when the spindle 55a of the operation unit 55 is rotated to open and close the valve portion 54 of the water stop valve 102, movement of the water stop valve 102 by the action of the operation force can be suppressed. The operation can be performed stably.

Further, as shown in FIGS. 1 and 4, when the first arm 2 and the second arm 3 are not engaged, the distance between the first contact portion 22 and the second contact portion 24 is expanded. ing. Therefore, when the abutted portion 54 a of the water stop valve 102 is disposed between the first abutment portion 22 and the second abutment portion 24, the first abutment portion 22 and the second abutment portion 24 fail. And the installation of the water stop valve 102 is improved.

When holding the water stop valve 102 in the holder 101, it is also possible to select that the abutted portion 54a of the water stop valve 102 be located other than between the first contact portion 22 and the second contact portion 24. It is possible. If the selection is performed, the rotation of the water stop valve 102 about the pipe axis L can not be suppressed, but the direction of the water stop valve 102 (operation portion 55) around the pipe axis L is as shown in FIG. It will not be limited to the state of For example, depending on the construction conditions of the water supply, the direction of the operation unit 55 may need to be prioritized over suppressing the rotation of the water stop valve 102. In such a case, the selection is performed Good.

(Another Example) The present invention can also be implemented, for example, in the following manner. The first contact portion 22 is configured separately from the first arm 2, and a plurality of attachment portions to which the first contact portion 22 can be attached are provided along the extending direction of the first arm 2. Further, the second contact portion 24 is configured separately from the second arm 3, and a plurality of attachment portions to which the second contact portion 24 can be attached are provided along the extending direction of the second arm 3. .

Then, the direction around the pipe axis L of the water stop valve 102 (the operation unit 55) is made different from the state of FIG. 8 and at the same time the rotation around the pipe axis L of the water stop valve 102 is also suppressed In this case, the mounting position of the first contact portion 22 in the first arm 2 and the mounting position of the second contact portion 24 in the second arm 3 are adjusted to correspond to each other.

A protrusion is provided on one side edge of the first arm 2 and / or one side edge of the second arm 3, and a concave portion capable of receiving the abutted portion 54a of the water stop valve 102 is provided on the protrusion. Then, the direction around the pipe axis L of the water stop valve 102 (operation portion 55) is made different from the state of FIG. 8 and it is desired to suppress the rotation around the pipe axis L of the water stop valve 102 as well. In this case, the abutted portion 54a is inserted into the concave portion to correspond thereto.
