Abstract

This invention relates to a flush toilet bowl, in particular, a stool type flush toilet bowl, in which the rear bottom surface (1') of the bowl part (1) of the toilet bowl main body (A) is formed into a roughly V-shaped recess (a) in cross-section so that fluctuation in directions of flush water flows may be decreased and energy of water flow may be concentrated in spite of fluctuation in size and position of the water flushing rim hole.
