When the knob 61 is rotated in this state, the spindle 62 is rotated, and the arm 83 lifts the chain 84 to open the drain valve 13. By the way, the illustrated spindle 62
Two sets of arms 83 and chains 84 are provided, one for large washing and one for small washing, respectively. Only one arm selectively moves according to the rotation direction of the knob 61.

According to the shape of the outer container 3, the shank 81
Can be adjusted in the distance at which the spindle is inserted into the spindle 92. For example, FIG. 14 shows a case where the outer container 3 having a size larger than that of FIG. 10 is used. In this case, the inner container 2
The distance from the side wall 2c of the outer container 3 to the side wall 3c of the outer container 3 is larger than that in the case of FIG. Therefore, the shank 81 is inserted into the spindle 92 at a shallower depth than in the case of FIG. 10, and is fixed to the spindle 92 by the retaining ring 90 at the locking recess 63 on the more distal end side. In this way, it is possible to cope with variations in the shape of the outer container 3. On the other hand, since the length of the spindle 62 is fixed to an optimal size according to the design of the inner container 2, even when the shape of the outer container 3 changes, the length of the chain 84 is not particularly required.

FIGS. 15 to 17 show a second embodiment of the present invention. 15 is a cross-sectional plan view, FIG. 16 is a cross-sectional view taken along line (16)-(16) in FIG. 15, and FIG.

On the other hand, the outer container 3 functions as a mere casing that covers the outer side of the inner container 2 and adjusts the appearance of the water tank. Fulfill mainly. Therefore, when manufacturing various water tanks corresponding to various toilet models, a variety of designs are prepared only for the outer container having a simple configuration, and a common design is used for the inner container having a complicated configuration. You. As a result, assembling work is simplified, assembling time is shortened, the number of parts is reduced, and the total manufacturing cost is significantly reduced as compared with the related art.
In particular, if the inner container is made of a synthetic resin and the attached parts are formed as integrally with the inner container as possible, the effect of cost reduction is particularly high. The plumbing work at the time of installing the toilet is hardly different for each model, and it becomes easy. In addition, since only the outer container or only the inner container can be repaired or replaced, it is convenient for the user.

In order to simplify the connection work between the connection between the cylinder 5 and the cylinder on the bottom wall of the container or the connection between the external water supply pipe 24 and the ball tap 12, it is also possible to use a so-called one-touch detachable coupler. Since the structure of the one-touch detachable coupler is well known, its configuration will not be described in detail here, but only the outline will be described in that the plug attached to the end of one tube is inserted into the socket at the end of the other tube. The socket is automatically connected so that the plug does not bite the plug so that the plug and the socket do not come off. Also, the two can be easily separated by releasing the lock by a predetermined operation and pulling them apart. This one-touch detachable coupler is highly effective in facilitating work in the above-described embodiments and modifications, particularly when used for connection of the external water supply pipe 14.

The various structures relating to the water supply pipe shown in FIGS. 6 to 9 and FIGS. 18 to 27 are not limited to the tank having the double container structure according to the present invention, but also to the conventional general single container structure. The present invention can be applied not only to the case where the water supply pipe is fixed to the tank bottom wall, but also to the case where the water supply pipe is fixed to a wall other than the bottom wall.

Next, a modification of the structure for attaching the drainage handle 60 to the tank will be described with reference to FIGS.

FIG. 29 shows a first modification. FIG. 30 is a cross-sectional view of the spindle 62 and the shank 81 taken along line (30)-(30) in FIG. FIG. 31 shows (31) of FIG.
It is a longitudinal section of shank 81 in the-(31) line.

As shown in FIG. 29, the spindle 62 of the drain lever 60 is inserted through and fixed to a spindle guide 64 attached to the inner container side wall 2c. The shank 8 from the knob 61 is inserted into the engagement hole 73 in the spindle 62.

The tip of the shank 163 reaches the inside of the inner container 2 through the notch 168 formed in the side wall 2c of the inner container 2. Inside the shank 163, a deep engagement hole 166 is formed along the central axis from the tip surface. The proximal end portion of the spindle 167 having the arm 83 at the distal end is inserted into the engagement hole 166. On the inner surface near the notch 168 of the side wall 2c of the inner container 2, a positioning bar 169 for deciding an appropriate position of the arm 83 is provided upright. The spindle is moved until the tip of the positioning bar 169 contacts the arm 83. 167 is inserted into the shank 163.

At the tip of the shank 163, the fixing pin 14
2 is externally fitted. The fixing pin 142 fixes the spindle 167 to the shank 163 according to the same principle as that shown in FIGS. Near the distal end of the positioning bar 169, there is a neck 171 that is thinned so that it can be easily folded. After the spindle 167 is fixed to the shank 163 so that the positioning bar 169 does not hit the arm 83 when the arm 83 moves, the portion of the positioning bar 169 beyond the neck 171 is broken and removed.

Note that the positioning bar 169 may be provided on the arm 83 side. Forming the positioning bar 169 on the arm 83 side is generally easier. When the positioning bar 169 provided on the arm 83 obstructs the operation of the arm 83, it is preferable that a part or all of the positioning bar 169 can be cut off.
