PROBLEM TO BE SOLVED: To provide a complementary differential pressure type water flow control structure capable of achieving a water saving function. SOLUTION: This complementary differential pressure type water flow control structure is provided with a nut 1, a body 2, a spindle 3, an elastic component 4 and a piston 5. The elastic component 4 is fitted onto the spindle 3, and inserted into a gradually-narrowed hole 23 of a first end surface 21 of the body 2 after one end of the spindle 3 is screwed and fixed to the piston 5. The other end of the spindle 3 is fixed to be screwed by the nut 1 in the outside of a second end surface 22 of the body. Thus, the spindle 3, the elastic component 4 and the piston 5 operates in the body 2. When the piston 5 receives various kinds of water pressure to be moved, the spindle 3 is moved by the piston 5 and the elastic component 4 in conjunction with them, and slidably moved in the body 2. The size of a gradually-reducing space of the hole 23 in the body 2 is changed in response to the slide position of the piston 5, the water volume can be adjusted, a state of water pressure balance is formed, and a water-saving function can be achieved.
