[Prior art]
Some toilet equipment is configured to supply toilet flushing water to a toilet bowl of a toilet bowl from a low tank installed on the upper rear surface of a Western-style toilet bowl, and is provided with a row tank cover that covers the row tank. A toilet seat is attached to the low tank cover so as to be rotatable in the up-and-down direction.
[0003]
Dirt such as urine is infiltrated between the low tank cover and the upper surface of the Western-style toilet bowl, which is likely to cause odor. In view of this, a proposal has been proposed in which the low tank cover can be moved up and down by a lifting device with respect to the western-style toilet using a guide member, and the low-tank cover is moved upward together with the toilet seat when the western-style toilet is cleaned (JP-A-9-28619). Publication).
[0004]
If the low tank cover can be simply moved up and down, flushing, that is, toilet flushing water may flow out during cleaning, and the cleaning staff may be splashed with water, or the cleaning tool may be washed away with water.
[0005]
In view of this, the present applicant has proposed in Japanese Patent Application Laid-Open No. 2000-104307 an improved toilet equipment with a toilet seat up-and-down movement function that prevents the flushing of flush toilet water when the low tank cover rises. Yes.
[0006]
FIG. 8 shows an embodiment of the same publication in which the manual flush handle is configured not to raise the float valve when the low tank cover is lifted. The handle 150 is provided on the low tank cover 156 and the handle shaft 152 is provided on the low tank cover. Projecting into 156. The tip of the shaft 152 is a flat plate portion 154.

[0007]
When the low tank cover 156 is at the lower limit, the flat plate portion 154 is fitted into the groove 164 and the rotation of the handle 150 is transmitted to the shaft 160 as it is. When the low tank cover 156 is raised (floated), the flat plate portion 154 is detached from the groove 164 and the shaft 152 and the shaft 160 are separated. For this reason, when the low tank cover 156 is in the raised state, the float valve is not pulled up even if the handle 150 is turned, and the toilet flushing water is not discharged from the low tank 158.
[0008]
[Problems to be solved by the invention]
In the conventional example shown in FIG. 8, since the shafts 152 and 160 need to be accurately coaxially arranged when the low tank cover 156 is lowered to the lowering limit, the raising and lowering guide mechanism of the low tank cover 156 and the low tank 158 are arranged. position must accurately perform 置合 Align, it takes time and labor to assembly work of the low tank 158 and the low tank cover 156.
