Abstract
A blower apparatus has a drive motor and a blower device operatively connected to the drive motor. A blower tube is connected to the blower device and has an outlet opening remote from the blower device. A blower air stream conveyed by the blower device passes through the blower tube in the direction of a longitudinal center axis of the blower tube and exits through the outlet opening in an outflow direction. A pivoting device that pivots the blower tube is provided. A nozzle is supported to be freely pivotable on the blower tube about at least one pivot axis, wherein the outlet opening is formed on the nozzle. The nozzle forms the pivot device for pivoting the blower tube and utilizes a transverse force that is generated by the blower air stream in the nozzle for pivoting the blower tube.
