As such a joint 2, there is known a rotary type in which the instrument-side main body 3 and the hose-side main body 4 are rotatable so that the hose H is not twisted when the watering nozzle 1 is used. I have. In the rotary joint described in JP-A-4-78458, although not specifically shown, a part of the instrument-side main body is rotatably inserted into the hose-side main body. Then, a ring-shaped connecting member is fitted from the outer peripheral surface of the hose-side main body toward the instrument-side main body, so that both main bodies are rotatable while restricting their detachment.

る。[0003] Here, the ring-shaped connecting member is rotationally slid between the instrument-side main body and the hose-side main body, and tends to spread outward due to the rotational sliding friction. Therefore, the connecting member may come off during use of the watering nozzle, and water leakage may occur. Alternatively, even if the connecting member does not come off directly, a part of the connecting member may protrude outward from the hose-side main body, which may be caught by a stone on the ground and eventually come off. Therefore, in this rotary joint, a cover is placed over the outer peripheral surface of the hose-side main body so that the connecting member does not come off, and the cover is fixed.

う必要がある。In a rotary joint in which the instrument side body and the hose side body are rotatable, when the two main bodies are assembled, a seal member for preventing water leakage is interposed between the assembled parts. There must be. However, since the two main bodies rotate relative to each other, the sliding friction may wear the seal member. Therefore, it is necessary to perform maintenance such as replacement of the seal member.

Since the cover is fixed to the outer peripheral surface of the hose-side main body with an adhesive or the like in order to prevent the connection member from being detached, these main bodies cannot be disassembled once both main bodies are assembled. Therefore, maintenance such as replacement of the seal member cannot be performed, and there is no problem with the joint itself. However, only the seal member is worn, and the life of the joint is eventually shortened. In addition, if the cover is provided, the number of parts increases correspondingly, and the cost increases.

３、４が分解して、水が漏れるような心配はなくなる。Next, the operation of the rotary joint of this embodiment will be described. As shown in FIGS. 1 and 2, when the tubular member 17 is tightened, the tubular member 17 is located exactly on the connecting member 10 and covers the connecting member 10. Therefore, even if the connecting member 10 is disengaged, the cylindrical member 17
It is regulated that it comes off when it hits. Then, in a situation where the watering nozzle is used, since the tubular member 17 is always in a tightened state, the connecting member 10 does not come off at that time. Therefore, during use of the watering nozzle, there is no fear that the main bodies 3 and 4 are disassembled and water leaks.

テナンスが可能となる。On the other hand, when the tubular member 17 is loosened, the tubular member 17 moves in a direction away from the hose side main body 4, and
The connecting member 10 is shifted from above. In this state, the connecting member 1
If 0 is pushed open, it can be removed from the fitting groove 23 of the hose side main body 4. If the connecting member 10 is removed from the fitting groove 23, the instrument-side main body 3 and the hose-side main body 4 can be disassembled, so that maintenance such as replacement of the O-ring 22 can be performed.

中に連結部材１０が外れてしまうおそれが生じる。Note that, depending on the thickness of the hose H, the cylindrical member 1
7 may have a slight difference. For example, when a thick hose H is used, the hose H is firmly sandwiched by only slightly tightening the tubular member 17, so that the tubular member 17 cannot be moved further. Therefore, if the tubular member 17 cannot be moved before being positioned on the connecting member 10, there is a possibility that the connecting member 10 may come off during use of the watering nozzle.

The tubular member 17 can be positioned on the connecting member 10. However, if the width h of the connecting member 10 is increased, the widths of the slide groove 12 and the fitting groove 23 must be increased accordingly. If the widths of the slide groove 12 and the fitting groove 23 are widened, as can be seen from FIG. 1, there arises a problem that the seal groove 9 cannot be secured or the screw portion 18 cannot be sufficiently secured.

題も生じない。The projection 28 extending along the outer peripheral surface of the hose-side main body 4 projects in the moving direction of the tubular member 17. Therefore, even if the cylindrical member 17 can be moved only a little by using the thick hose H, the cylindrical member 17 can be positioned at least above the protrusion 28. And
If the tubular member 17 is positioned at least on the projection 28, the connecting member 10 can be prevented from coming off.
In addition, if the protrusion 28 is provided, the width h of the connecting member 10 itself is increased.
It is not necessary to increase the width, and there is no problem that the seal groove 9 cannot be secured or the screw portion 18 cannot be secured sufficiently.

い。According to the first aspect of the present invention, the outside of the hose side main body is provided.
A connecting member fitted from the peripheral surface toward the appliance side main body,
With elasticity, this connecting member can be easily
Can be removed. By removing the connecting member in this manner , the hose-side main body and the appliance-side main body can be disassembled, and maintenance such as replacement of the seal member can be easily performed. However, when the tubular member is at the position for holding the hose, the tubular member is located on the connecting member. Therefore, in that state, it is possible to prevent the connecting member from being detached by being restricted by the cylindrical member.
And, in a situation where a device such as a watering nozzle is used, since the tubular member is always at the position for holding the hose, the connecting member is prevented from being detached at that time, and there is no fear that both the main bodies may be inadvertently disassembled. be able to. In addition, since the cylindrical member is originally provided in the rotary joint, there is no need to use a separate member and the cost is not increased.

Therefore, it is possible to widen the stroke range of the tubular member that can prevent the connecting member from being detached, and to cope with a case where the stroke of the tubular member varies depending on the thickness of the hose.
In addition, since it is not necessary to increase the size of the connecting member itself, the influence on other parts can be reduced, and the rotary joint does not become large.
