Abstract
A blower tube connected to a blower of an air-jet type cleaner comprises a straight tube part having one end connected to the blower; and a deflecting part, extending from the other end of the straight tube part, for receiving an airflow within the straight tube part and deflecting thus received airflow. A nozzle for jetting out the airflow deflected by the deflecting part is defined in the straight tube part and deflecting part. The deflecting part does not protrude sideways from the straight tube part. In this configuration, the blower tube can be handled as if it is a straight rod-like body, and can be inserted into a narrow space for cleaning.
