The filter 56 rotates from the air suction supply source 8 while revolving around the first axis Y and rotating around the second axis X.
. Are jetted three-dimensionally radially from jet ports 59, 59a.

Here, when the gear ratio of the gear mechanism 62 is an integer, the rotation of the blower tube 56 by one revolution causes an integer number of revolutions. Therefore, when it is positioned at the same revolution angle, the same rotation angle is obtained. As a result, the direction of air injection is constant.

Next, when the decimal point of the gear ratio of the gear mechanism 62 is a predetermined number of digits, for example, an infinite decimal number, the blower tube 56
Does not rotate an integer number of times even if it revolves one time, so that it always rotates too much, even the fractional part below the decimal point. Changes constantly.

When the gear ratio is not an infinite decimal number but a finite decimal number, the injection direction changes during a predetermined number of revolutions, and thereafter, the same pattern is repeated.

In the cleaning device 45 in which the pitch surfaces P of the bevel gear 47 are formed at predetermined angles, as shown in FIG. 10, the pinion gear 61 and the bevel gear 47 on one side of the blower tube 56 are engaged. In the meantime, since the pinion gear 61a on the other side of the blower tube 56 does not mesh with the bevel gear 47, one of the blower tubes 56 rotates in the forward direction with respect to the revolving direction.
The other rotates in the direction opposite to the revolution direction.

Further, when the blower tube 56 revolves and the pinion gear 61 on one side of the blower tube 56 does not mesh with the bevel gear 47, the pinion gear on the other side of the blower tube 56 is turned on.
As a result, one of the blower tubes 56 rotates in the opposite direction to the revolving direction, while the other of the blower tubes 56 rotates in the forward direction with respect to the revolving direction. The rotation direction of the blower tube 56 is reversed between the normal and reverse directions.
