Here, the guide surface 138 has an upper surface portion 141 and a side surface portion 142 in which slits 140 are formed as shown in FIG. 8, and a pair of adjacent upper and lower portions attached to the attachment portions 116 and 118. The lower balls 36c of the balls 36a, 36c are accommodated in a state in which the lower balls 36c are covered from the outside in the left-right direction.

The slit 140 brings the ball chain connecting material 40 through the guide surface 138 to the insertion holes 120 of the mounting portions 118 and 116 when the ball chains 36 and 38 are mounted to the mounting portions 118 and 116. belongs to.
At this time, the lower ball 36c is first fitted into the inside of the guide surface 138 from the lower end of the slit 140, and in this state, the connecting member 40 together with the upper ball 36a along the slit 140 side Move to.

  Further, in order to prevent the ball chains 36 and 38 brought into the insertion hole 120 from falling off the slit 140, the mounting portions 118 and 116 are formed on a part of the upper surface portion 141 of the guide surface 138 provided with the slit 140. An inclined surface 139 that is inclined upward in the direction away from the center is provided. As a result, as shown in FIG. 8B, when the spindle 96 rotates and a downward force is applied to the ball chains 36 and 38, the inclined surface 139 supports the ball chains 36 and 38, thereby The movement is suppressed, and the ball chains 36 and 38 are configured not to fall out of the slit 140.

Next, the operation of this embodiment will be described.
In this embodiment, when the cleaning handle 94 is in the neutral state shown in FIG. 5, the valve portions 28 and 29 of the flapper valve 22 are closed as shown in FIG. 9, and the float 44 is submerged in water. The position is in contact with the stopper 90 at the position.

When the cleaning handle 94 is rotated from this state to the large cleaning side, that is, counterclockwise, the lifting arm 124 provided on the lever portion 112 rotates in the same direction, and the tip end portion 124a is moved to the large cleaning ball chain 38. Then, the ball chain 38 is pulled up by a predetermined distance by hooking the lower portion of the mounting portion 116 by a predetermined distance.
Thereby, as shown in FIG. 10, the valve parts 28 and 29 are pulled up integrally. Specifically, since the valve portion 29 is formed so as to have an opening 70 communicating with the drain port 20 at the center thereof, the valve portions 28 and 29 remain closed with the valve portion 28. Will be opened together. These valve portions 28 and 29 are maintained in an open state by the buoyancy of the floats 44 and 46 and are drained toward the toilet from the drain port 20 where the wash water in the tank 10 is opened.
Thereafter, the water level in the tank descends as the washing water in the tank 10 drains.
Then, when the water level is lowered to a lower position by a certain distance, the buoyancy acting on the floats 44 and 46 and the gravity of the valve portions 28 and 29 and the floats 44 and 46 themselves are in a balanced state. As the valve descends, the valves 28 and 29 are moved downward to close.

  On the other hand, when the cleaning handle 94 is rotated on the small cleaning side opposite to that at the time of large cleaning, that is, in the above-described clockwise direction, the lifting arm 124 of the lever portion 112 now has its tip end 124a connected to the ball chain 36 for small cleaning. The ball chain 36 is pulled up by a predetermined distance.

  As a result, only the valve portion 28 is pulled up as shown in FIG. 11, and the opening 70 of the valve portion 29 communicating with the drain port 20 is opened, so that the cleaning water in the tank 10 passes through the opening 70. The water is discharged from the drain 20 toward the toilet.

At the time of this small cleaning, the valve portion 28 is maintained in an open state by the buoyancy of only the float 44, and the position of the float 44 is higher than the position of the float 46. Close the valve.
Therefore, at the time of small washing, the amount of drainage of washing water is small and toilet flushing is performed with a small amount of water.

As described above, the cleaning operation device 92 according to the present embodiment does not cause the large cleaning ball chain and the small cleaning ball chain to fall out of the slit due to the rotation of the spindle, unlike the conventional cleaning operation device. Operation becomes possible.
That is, by providing an inclined surface 139 that is inclined upward in a direction away from the mounting portions 118 and 116 in a part of the guide surface 138 in which the slit is formed, the spindle and the lever portion rotate, and the ball Even when a downward force is applied to the chains 36 and 38, the slanted surface 139 can suppress the movement of the ball chains 36 and 38 and prevent the ball chains 36 and 38 from falling out of the slit.

Next, a second embodiment will be described with reference to FIG. Below, it demonstrates centering on a different point from 1st Embodiment.
As shown in FIG. 12, in the spindle and lever portion of the second embodiment, a lower ball insertion portion 52 is formed on a part of the guide surface 138. Therefore, in order to attach the ball chains 36 and 38 to the attachment portions 118 and 116, it is only necessary to fit the lower ball 36 c of the ball chains 36 and 38 from the lower ball insertion portion 52 to the inside of the guide surface 138. In a state where the chain is hung downward, it can be attached by moving horizontally from the side, and attachment work becomes easy.

Next, a third embodiment will be described with reference to FIGS.
As shown in FIG. 13, in the spindle and lever portion of the third embodiment, the slit 140 is formed by bending and is also provided on the regulation wall 128. And the lower ball insertion part 52 is formed in a part of slit 140 provided in the control wall 139 similarly to 2nd Embodiment.

  The method of attaching the ball chains 36 and 38 in the third embodiment is as follows. First, the ball chains 36 and 38 are inserted from the regulation wall 128 side. At this time, the ball chains 36 and 38 are bent in accordance with the shape of the slit 140 formed in the restriction wall 128 in advance, and the lower ball 36 c of the ball chain is fitted into the guide surface 138 from the lower ball insertion portion 52. Move the ball chain so that. The connecting material 36b between the upper ball 36a and the lower ball 36c moves along the upper slit 120a, and the connecting material 36d provided under the lower ball 36c extends along the lower slit 120b. Move. Thereby, the ball 36a on the upper side of the ball chain is guided to the mounting portions 118 and 116, and the ball chain is in a state of hanging downward.

  In the third embodiment, a part of the upper slit 120a is formed along the axial direction of the spindle 96, and is oriented in a direction perpendicular to the rotation direction of the head portion 114 of the lever portion 112. Therefore, the spindle 96 is rotated. As a result, the ball chain does not fall out of the slit 120 even when the head portion 114 of the lever portion 112 rotates. That is, since the upper slit 120a is provided in a direction orthogonal to the rotation direction of the head portion 114 of the lever portion 112, even if a downward force is applied to the ball chains 36 and 38, the upper slit 120a Therefore, the ball chain does not fall out of the slit 120 because the force is not in the direction of falling off.

  In the third embodiment, as in the first and second embodiments, an inclined surface 139 is formed on a part of the upper surface portion 142 of the guide surface 138 in which the slit is formed, and the ball chain 36 , 38 prevents the ball chain 36, 38 from falling out of the slit 120, no matter what force is applied.

  Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention varies the position of the ball chain attachment portion in the front-rear direction in the front view with respect to the spindle, for example, on the large washing side and the small washing side. It is also possible to make them different in the height direction, and it is also possible to provide the ball chain attachment part at a location different from the above. The present invention can be configured in various modifications without departing from the spirit of the present invention.
