PROBLEM TO BE SOLVED: To favourably balance a flow rate separated from a Y pipe. SOLUTION: An opening adjusting sleeve 2 made of a flexible elastic material as rubber, etc., is loaded in the inside of a branched pipe body 1 free to elastically deform, a pressure rod 3 is arranged on the outside of an intermediate part of the opening adjusting sleeve 2 in its diametrical direction, at the time of adjusting a flow rate of a fluid material in accordance with its advance and retreat, a hydraulic pressure pressure chamber filled with oil is formed in a cavity between a hydraulic pressure working sleeve made of a flexible elastic material of rubber, etc., loaded in the inside of a large diametrical pipe body on the lower converting side and an inner peripheral surface of the large diametrical pipe body is formed, a plural number of elastic force support bodies elastically pressurized by springs on a plural number of points in the longitudinal direction are arranged on an outer periphery of the hydraulic pressure working sleeve free to advance and retreat in the diametrical direction of the hydraulic pressure working sleeve, and at the time when pressure of the fluid material force fed in the inside of the hydraulic pressure working sleeve pressurizes oil in the hydraulic pressure chamber by competing with the elastic force support bodies, contact quantity is adjusted by advancing and retreating the pressure rod 3 by its pressure oil.
