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 an attachment (44) to be coupled to the distal end (42a) of the tube main body (42) and including 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 distant position to protrude radially inward toward an axial line of the blower tube (4). The first projections (46) on the tube main body (42) and the second projections (48) on the attachment 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 caused by ejection of a high-speed airflow.
