9 comes into contact with the vibrating cam 17, and the action of the vibration cam 17 is transmitted to the polishing plate 21 via the contact protrusion 19.

In the above configuration, when the drive unit 4 is energized by driving the drive unit 4, the drive force is applied to the drive pulley 6a, the belt 9, the driven pulley 6b, and the eccentric pin 6
and transmitted to the oscillator 12 via the eccentric ring 6e and d.
The rocking body 12 is rocked. Then, the swinging motion is transmitted to the vibration cam 17 through the arm plate 13,
The vibrating cam 17 pushes the contact protrusion 19 according to the swinging motion of the arm plate 13. Then, the vibration plate 18 moves up and down (vibrates) in the mounting frame plate 20 due to the interaction between the own weight of the suction port main body 1 and the pressing force of the vibration cam 17, and the polishing cloth 2
2 will polish the floor.

FIG. 22 shows a variation of FIG.
A suction inflow path (dotted line 90) communicating with the suction port 2 of the suction port body.
Is shown in the floor polishing apparatus. In FIG. 22, the same members as those in FIG. 11 are denoted by the same reference numerals. According to the configuration of FIG. 22, when the floor polishing apparatus is attached to the suction port and used as an empty wipe without spraying wax, the empty wipe can be performed while sucking hair and dust on the flooring. Further, when the suction port comes into contact with the wall, the effect of suction is greatly exhibited.

Fourth Embodiment FIG. 21 shows that since the movable brush unit driven by the motor 4 is driven on one side, the pivot shaft at the other end inevitably oscillates (reciprocal swing). An embodiment in which an angle regulating mechanism is provided to regulate a shake is shown. This angle regulating mechanism is provided, for example, instead of the mechanism shown in FIGS.

In FIG. 21, a turning arm (turning member) 80 is fixed to the pivot 11 of the movable brush.
Reference numeral 81 denotes a fixed arm (an immovable member) that rotatably supports the pivot 11. The fixed arm 81 is fixed to the lower frame 1b. FIG. 21A is a diagram of the rotating arm 80 viewed from the left end, and FIG. 21C is a diagram of the fixed arm 81 viewed from the right.

An elliptical through hole 82 is formed in the fixed arm 81, and a pin 83 of the rotating arm 80 is inserted into the through hole 82. Therefore, when the pivot shaft 11 rotates, the rotation is in a range where the pin 83 can move in the through hole 82, and as a result, the rotation of the pivot shaft 11 is restricted. In FIG. 21C, the pin 83 is a solid line 8
It only moves between the position indicated by 3a and the position 83b indicated by the dotted line, and the angle is about 16 °.

The through-hole 82 is formed by a cylindrical portion 84, which is in contact with a leaf spring 85 at a lower portion. The leaf spring 85 is mounted on the rotating arm 80, and has a mountain shape at the center as shown in FIG. 21A. When the pivot 11 is rotated, the cylindrical portion 84 has the mountain shape. Strongly receives friction from the fixed arm 81, and consequently receives a braking action. This also provides a vibration damping effect.
