摘要：PROBLEM TO BE SOLVED: To provide an air flow measurement device 1 withwhich it is possible to reduce the inflow of dust D taken in from a main bypass 11 into asub-bypass 12.SOLUTION: A housing 4 of an air flow measurement device 1 comprises achange wall 31 for changing the flow direction of passing air AF taken in from an intakeport 13 to the upstream side of a branch portion 21 of a sub-bypass 12 from a mainbypass 11. The change wall 31 includes an intake port side face 46 that does not lie atright angles to the arrangement direction of the intake port 13 and the change wall 31.Thus, the dust D bumps against and rebounds on a recessed surface 46a of an outercircumferential wall 33 of a first curve 15 and again bumps against the recessed surface46a. Therefore, as the kinetic energy of the dust D can be reliably deprived, it is possibleto further reduce the amount of dust D taken in from the main bypass 11 into the sub-bypass 12.SELECTED DRAWING: Figure 4
