[0002]

[Prior art]

 The tank lid of a tank-type flush toilet has conventionally been equipped with an auxiliary facility for hand washing, and drainage water after hand washing is temporarily stored in the tank through a round hole for drainage provided in the bottom of the recess in the tank lid.

However, in this case, there is a risk of closing the round hole for drainage in the recess of the lid. If used with the holes closed, water could overflow from the dents in the lid and could eventually flood the toilet.

[0004]

[Means for Solving the Problems]

 The present invention has a hole shape that does not block the bottom hole even if an object is placed in the recess of the tank lid, and was realized without increasing the number of parts.
