Here, the reason why the power transmission unit is composed of a plurality of gears is to meet the reduction ratio while occupying little space.

That is, the rotational speed of the first cleaning member 100 is set to be larger than the rotational speed of the second cleaning member 200. At this time, when a single gear is used to match the reduction ratio, the size of the gear is increased. The space in which the gear can be placed cannot be secured.

However, when using a plurality of gears as in this embodiment, it is possible to match the reduction ratio while occupying little space.

In detail, the second guide part 320 is formed by extending the rotation shaft 324 of a predetermined length. In addition, the rotation shaft 324 penetrates through the first gear seating portion 340, and the first gear 350 is coupled to the rotation shaft 324 through.

In addition, the second gear 360 includes an inner gear 362 engaged with the first gear 350 and an outer gear 364 having a smaller size than the inner gear 362. In addition, the second gear 360 is coupled to the rotation shaft 344 formed on the first gear seating portion 340.

In addition, one side of the third gear 370 is engaged with the outer gear 362, and the other side of the third gear 370 is engaged with the fourth gear 380.

In this case, as described above, the state in which the first guide part 310 and the second guide part 320 are engaged by the elastic member 350 is maintained.

And, when the first gear 350 is rotated in the clockwise direction, the second gear 360 is rotated in the counterclockwise direction, when the second gear 360 is rotated in the counterclockwise direction, the third gear 370 is rotated clockwise.

When the third gear 370 is rotated counterclockwise, the fourth gear 380 is rotated counterclockwise when viewed from above. As a result, the second cleaning member 200 is rotated counterclockwise by the counterclockwise rotation of the fourth gear 380.

On the other hand, referring to FIG. 5, when the first cleaning member 100 and the second cleaning member 200 are rotated at the same time, the second cleaning member 200 is not rotated due to an obstacle or the like. The power transmission part connected to the cleaning member 200, that is, the first to fourth gears 360 to 380, and the second guide part 320 do not rotate.

In this state, the rotational force of the rotary motor 30 is continuously transmitted to the first guide part 310. Then, the unevenness 312 of the first guide part 310 receives a resistance force from the unevenness 322 of the second guide part 320 while the elastic member 330 is compressed, so that the first guide part 310 The unevenness 312 of) passes over the unevenness 322 of the second guide part 320.

In addition, while the second cleaning member 200 is stopped, the unevenness 312 of the first guide part 310 rotates while repeating the process of riding over the unevenness 322 of the second guide part 320. do.
