摘要：A blower tube (4) to be connected to a power blower has a tube main body (42)having a distal end portion (42a) diminished in diameter toward its distal end and anattachment (44) to be coupled to the distal end (42a) of the tube main body (42) andincluding a distal end portion (44a) gradually diminished in diameter toward its distal end.
Both these distal end portions (42a, 44a) are each provided three projections at distantposition to protrude radially inward toward an axial line of the blower tube (4). The firstprojections (46) on the tube main body (42) and the second projections (48) on theattachment are positioned offset in phase to align in an alternate order. The blower tube(4) having the projections (46, 48) at the distal end portion can reduce the noise causedby ejection of a high-speed airflow.
