PROBLEM TO BE SOLVED: To provide a low-pressure fuel injection device having good fuel controllability and excellent in atomizing characteristics. SOLUTION: An opening part 8A of a nozzle 8 in which bleed hole 8D is formed toward an inner passage 8B is opened to a venturi part V formed together with a negative pressure operating valve P, and the outer periphery 8C of the inner passage 8B is arranged in an annular chamber 9 with an annular clearance S. A rod-shaped member 10 is erected and arranged in the inner passage 8B of the nozzle 8 along the longitudinal axis of the nozzle 8 with a clearance P, and it is arranged so as to project from the opening part 8A of the nozzle 8 toward the venturi part V.
