<p>A floor nozzle for a vacuum cleaner which includes a housing (H), and an agitator (12), a driving motor (17) for the agitator (12), and a switch (29) for changing over rotating directions of the motor (17) which are accommodated in the housing (H), and a coupling pipe (4) connected to the housing (H) so as to be displaceable at least back and forth, and communicated with a suction passage to a vacuum cleaner main body (1), and an associating device (33) for transmitting the back and forth displacement of the coupling pipe (4) to the switch (29). The associating device (33) is adapted to be held at two stabilized positions with respect to a boundary dead point and provided with a movable member (35) arranged to be displaced through quick action, to one of the stabilized positions after passing through the dead point, with the movable member (35) being associated with the switch (29).</p> |
