Since the connection structure between the release wire and the device unit of the conventional example described in Patent Document 1 is connected to the outer end and the device unit by screwing, when the outer end and the device unit are screwed together, Rotation stress due to screwing is applied to the flange part of the release wire interposed between them, and the outer wire itself is twisted and twisted by applying a force in the direction in which the upper and lower surfaces of the flange part move relative to each other. End up. When such twisting / twisting stress is applied to the outer tube, the outer tube is deformed or broken. Also, if the outer tube is deformed, it will interfere with the inner wire that can be moved forward and backward, and the outer tube will be broken by the friction that occurs when the inner wire moves forward and backward. Therefore, it is better not to apply torsion and torsional stress to the outer tube.
In addition, since the outer end is not fixed to anything during transportation to the release wire before construction, there is a problem that the outer end moves up and down around the release wire and the outer end is damaged.
Moreover, since the connection structure of the release wire and apparatus part of the prior art example which is the above-mentioned patent document 2 has connected the outer tube and the apparatus part with the diameter expansion of the apparatus part and the cap body, it adds to a cap body. Since the load must prevent the expansion of the diameter expansion and the connection of the release wire, fatigue damage of the cap body frequently occurs. It was a very problem because I did not do it. Moreover, since the said prior art must comprise a cap body as another member with respect to an apparatus part or an outer tube, the problem that a cap body was lost at the time of construction had generate | occur | produced. In addition, the construction procedure at the site increased the process of “attaching the cap body” by one, so the labor of the worker increased and the workability was poor.

From the above, the present invention solves the following problems.
1. Prevents the outer tube from being damaged by preventing rotational stress from being transmitted to the outer tube when connecting the outer end and equipment.
2. The outer end and the equipment part can be attached by a simple method, reducing work processes and improving workability.
3. While reducing the number of members, there is no risk of members being lost at the construction site.
4). Prevents the outer end from moving in the axial direction with respect to the outer tube during transportation, and prevents damage to the outer end before construction.

At this time, since the claw receiving portion 61 has a slit, the claw receiving portion 61 is elastically expanded by the claw portion 62, and when the claw portion 62 reaches the notch window portion of the claw receiving portion 61, the claw receiving portion 61 is elastic. The claw portion 62 can be elastically engaged with the claw receiving portion 61 easily. By doing so, the flange portion 121 of the outer tube 12 is engaged and fixed to the outer end 2 so as to be sandwiched between the outer end 2 and the stopper portion 3. Since the connection between the outer end 2 and the stopper portion 3 does not generate stress due to rotation of a screw or the like, the outer tube 12 is not twisted or twisted, and the outer tube 12 is not damaged. In addition, since the outer tube 12 and the outer end 2 are engaged and fixed, the release wire 1 is prevented from being damaged when the outer end 2 moves up and down around the release wire 1 during transportation to the release wire 1. Moreover, the work process which moves the outer end 2 to the apparatus part 4 side at the time of site construction reduces. In this way, the assembly of the release wire 1 at the factory is completed (that is, the state shown in FIG. 1C ).
Next, the construction procedure at the construction site will be described.
The operation unit 41 which is the device unit 4 is attached to the tank body S, and a drain pipe H and a drain trap are piped to the drain port K of the tank body S. Thereafter, the release wire 1 is connected to the valve body B side end of the remote-operated drain plug device, which is configured on the valve body B side of the drain port K. After that, as shown in FIG. 2A, the end of the release wire 1 on the operation unit 41 side (that is, the end side to which the outer end 2 is connected) is abutted against the end of the operation unit 41. At this time, the rod portion 111 of the inner wire 11 is inserted into the main body portion 43 of the operation portion 41 so that the rod portion 111 is disposed in the operation portion 41, and the stopper portion 3 of the outer tube 12 is inserted into the main body portion 43 of the operation portion 41. Butt. Thereafter, the connecting portion 7 of the outer end 2 with the device portion 4 is rotationally locked to the connecting portion 7 on the outer periphery of the main body portion 43 which is the device portion 4. Then, the outer end 2 and the device unit 4 are connected as shown in FIG . As a result, the flange portion 121 of the release wire 1 is connected to the operation portion 41 (device portion 4). Since the rotation force is not applied to the tube 12, no rotation stress is applied to the outer tube 12, so that the outer tube 12 is not broken or broken.
Moreover, also about a construction procedure, engagement is engaged only by abutting the stopper part 3 of the release wire 1 with respect to the apparatus part 4, and inserting the outer end 2 in the apparatus part 4, and it can connect by one touch. Therefore, workability improved.

The connection structure between the release wire and the device part in the above embodiment is the following drainage flow.
When the operation shaft 42 is pushed while the valve body B of the drain outlet K of the tank body S is lowered, the inner wire 11 of the release wire 1 moves forward in response to the pushing of the operation shaft 42. At this time, the urging spring 5 built in the release wire 1 is compressed. Then, since the release wire 1 is connected to the valve body B side, the valve body B is pushed up and raised as the inner wire 11 advances. In this state, the holding mechanism portion 44 in the main body portion 43 works to hold the advance amount of the inner wire 11, and the drainage port K of the tank body S is opened by holding the lift of the valve body B, Drainage in the tank body S is drained from the drain port K to the sewer pipe through the drain pipe H and the drain trap. Further, when the operating shaft 42 is pushed from this state, the inner wire 11 is advanced by a small amount, the holding of the inner wire 11 of the holding mechanism portion 44 in the main body 43 is released, and the inner wire 11 is compressed by the amount advanced. The compression of the biasing spring 5 is released along with the release of the holding mechanism 44, and the inner wire 11 is retracted by the bias of the compression release. As a result, the valve element B also descends due to its own weight as the inner wire 11 moves backward, so that the valve element B can be seated on the drainage port K and the drainage port K can be closed. In this state, since the drainage port K is closed, water can be stored in the tank body S. After that, the opening / closing action of the valve body B is repeated by the pushing operation of the operation unit 41.

In addition to the above-described embodiments, the present invention can be modified as appropriate without departing from the scope of the claims.
For example, although the outer end 2 is configured and arranged at the end of the outer tube 12 in the above embodiment, it may be configured at the end of the device unit 4 as shown in FIG .
Further, in the above embodiment, connecting the outer end 2 and the device unit 4, as shown in FIG. 6 (a), may be connected to the stopper portion 3 and the device unit 4.
Furthermore, the female member outer end 2 (or stopper 3) in the above embodiment, constitute a device unit 4 as the male member, the outer end 2 (or stopper 3) As shown in FIG. 6 (b) It is good also considering a male member and the apparatus part 4 as a female member.
Moreover, in the said Example, although the apparatus part 4 was used as the operation part 41 of the remote control type drain plug apparatus, for example, the drain plug raising / lowering mechanism part 45 of the remote control type drain plug apparatus as shown in FIG. It doesn't matter. The drainage valve raising / lowering mechanism part 45 at this time refers to, for example, a valve-side device. For example, a bearing part of a wire receiving member installed in the drainage cock may be used as the device part 4. Of course, both the operation unit 41 and the drain plug raising / lowering mechanism unit 45 may be used as the device unit 4.
