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. In a non-actuated state of the pivoting device the outflow direction is parallel to the longitudinal center axis of the blower tube. The pivoting device has a tilting device that tilts the outflow direction relative to the longitudinal center axis of the blower tube and utilizes a transverse force that is generated by the blower air stream at the outlet opening for pivoting the blower tube.
