2, and a storage recess 23 is formed in the support protrusion 22, and the storage recess 23 has inclined stopper parts 23a, as shown in FIG. 3, on both left and right sides of the upper end. 23b. 24 is a support base attached to the support protrusion 22 with a tatsu pin screw 25;
It has a support part 26 located above, and a pivot pin 28 which is a pivot part and projects from an arm part 27 extending from the support part 26 into the storage recess 23. Reference numeral 29 denotes a lever, which is pivotally supported by having its lower end fitted into the pivot pin 28 through its fitting hole 30 and housed together with the pivot pin 28 in the storage recess 23. At the same time, the upper end portion is inserted into and engaged with the engagement hole 21 of the operating member 17, so that the lever 29 is rotationally displaced about the pivot pin 28 by the sliding operation of the operating member 17. It is becoming more and more like this. Further, this lever 29 has an engagement hole 31 formed in the middle thereof. Here, the lower end of the lever 29 has its front and rear surfaces (left and right sides in FIG.
4 and the right inner wall of the storage recess 23 in the figure, and therefore the storage recess 2
It is housed in a locked state inside 3. Reference numeral 32 denotes an inverted dog-shaped bending lever that is bent as shown in FIGS. 3 and 4 at the intermediate portion 32a;

In FIG. 2, numerals 35 and 36 are an upper strainer and a lower strainer that close the opening of the overflow chamber 5 facing into the washing tub 2.

Next, the operation of the above configuration will be explained. Now, drain port 6
When the drain valve 8 is closed, as shown in FIG. 4, the slider 18 of the operating member 17 is located at the operation end position (operation start position) at the left end in the figure. On the other hand, the lever 29 is the bending lever 3
The other end 32c of 2 receives the biasing force of the compression coil spring 11 and the tensile force such as the own weight of the support body 9 through the string 33, so that it comes into contact with the left stopper part 23a of the storage recess 23. It is held in a tilted position. In this case, a gap G exists between the upper end of the lever 29 and the left end of the engagement hole 21 in the slider 18 of the operating member 17. From this state, move the operating member 17 to the operating panel 1.
3 in the direction of arrow A (to the right in the figure)
The sliding operation is performed through the position shown in FIG. 5 to the operation end position at the right end of FIG. 6. By operating this operating member 17, the lever 29 moves in the direction of arrow B in FIG. 4 about the pivot pin 28 with the left end of the engagement hole 21 of the slider 18 in contact with the upper end of the lever 29. At the same time, the rotation of the lever 29 causes the bending lever 32 to turn in the direction of the arrow B around the intermediate portion 32a, and the rotation of the bending lever 32 causes the support body 9 to be connected via the string 33. In turn, the drain valve 8 is displaced upward to open the drain port 6. In the state shown in FIG. 5, the tensile force (indicated by a vector f for convenience) applied to the other end 32c of the bending lever 32 via the string 33 is at the neutral position on the intermediate portion 32a, which is the center of rotation of the bending lever 32. Therefore, when the lever 29 rotates in the direction of arrow B from the state shown in FIG.
When the state shown in the figure is reached, the lever 29 is held in contact with the right stopper portion 23b of the storage recess 23. In the state shown in FIG. 6, a gap G still exists between the upper end of the lever 29 and the right end of the engagement hole 21 in the slider 18 of the operating member 17. , when the lever 29 changes from the state shown in FIG. 5 to the state shown in FIG.
This prevents it from colliding with the receiving slider 18, and the impact force of the folding is not transmitted to the operating member 17 and, by extension, the operating panel 13 side. On the other hand, in order to change the drain port 6 from the open state to the closed state by the drain valve 8, the operating member 17
This can be done by a sliding operation in the direction opposite to the above-mentioned arrow A, and even at this time, the gap G shown in FIG. 4 prevents any impact from being transmitted to the operating member 17.

In this embodiment, when the lever 29 is pivoted to the pivot pin 27 of the support base 4, the lever 29 is attached to the base 12 with the fitting hole 30 of the lever 29 fitted to the pivot pin 27. By simply storing the lever 29 in the storage recess 23 of the lever 29, the lever 29 can be prevented from coming off, and the ease of assembly can be improved compared to the conventional art.

Further, especially according to this embodiment, the stopper parts 23a and 23b formed at the upper end of the storage recess 23 receive the impact of the lever 29 when the operating member 17 is operated, and the impact force is reduced. Since the signal is not transmitted to the operating member 17, the operating feeling can be improved. Furthermore, since the stopper portions 23a and 23b are formed by the storage recess 23, they do not need to be provided separately and can be formed easily.

Note that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the lever 29
The relationship between the fitting hole 30 and the pivot pin 28 of the support base 24 may be reversed, and other modifications may be made as appropriate without departing from the spirit of the invention.

[Effect of idea]
