[0033] As shown in FIG. At this time, the returning of the contact member 8 may be performed through one embodiment of the separate return means described above, but may be performed by the own weight of the operation lever 100.

The length of the second lever 103 is preferably longer than the length of the first lever 102 so that the returning of the contact member 8 to the home position can be smoothly performed. 15 and 16, since the length of the second lever 103 is relatively longer than the length of the first lever 101 around the hinge 101 provided in the operation lever 100, The rotation range of the first lever 102 is relatively larger than the rotation range of the second lever 103. That is, since the height H of the second lever 103 is increased as the second lever 103 rotates, the distance L between the driving rods 6a connected to the contact member 8 is relatively increased. Even when the length of the outgoing outflow is relatively short, the drainage valve 5 is sufficiently opened so that drainage can be smoothly performed.

In other words, since the opening and closing of the drain valve is sufficiently performed in a state where the length of the contact member is relatively short, the driving line exposed to the outside of the toilet can be minimized and the aesthetic appearance can be improved. So that noise can be reduced.

15 and 16 show that the operation lever 100 is connected to the one end of the connecting member 7 formed in the water tank by the hinge 101. However, And may be rotatably coupled to a guide pipe 78 formed inside the tank or may be formed at a position close to the draw-out hole 11 or the draw-out hole 11 formed partly inside the water tank.

At this time, the first lever 102 of the operating lever 100 can be rotated on the upper portion of the connecting member 7, the guide pipe 78, or the drawing hole 11 to which the operating lever 100 is hinged And a driving rod 6a is also drawn through the cutout groove and is connected to one end of the first lever 102 in this state.

According to the present invention described above, the existing drain valve and the drive rope provided in the water tank are used as they are, and the connection member is installed in the water tank so as to penetrate the water tank. The driving rod is pulled out or drawn through the connecting member, so that it is possible to raise the habit of closing the toilet cover through a relatively simple structure change.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
