Abstract
A pump flow passagewhich extends in a flow direction Fand through which fluids introduced through first and second inlet pipeflow is disposed inside a main bodyof a purge pumpof an evaporative fuel processing device, a venturiwhich decreases in diameter toward downstream is formed in the pump flow passageat a position downstream of the first inlet pipein the flow direction F, the main bodyhas an upstream-side memberin which the first inlet pipeis disposed, and a downstream-side memberin which a discharge pipeis disposed, and connection facesof the upstream-side memberand the downstream-side memberare disposed upstream of the smallest diameter part, at which the inner diameter of the venturiis the smallest, in the flow direction F
