Description of the Related Art A bottomed cylindrical vibrator having a sieve mesh is supported on a base via a plurality of coiled springs, and a motor is installed below the bottom plate of the vibrator. The rotary drive shaft is vertically fixed so that it is on the center line of the vibrator body, the rotary drive shaft is projected from both ends of the motor main body, and the weight is fixed to the eccentric position, whereby the rotary drive shaft is fixed. A vibrating sieving machine in which the vibrating body is vibrated by rotating and rotating the weight is known from Japanese Patent Publication No. 7-41173 and many other publications.

った。By the way, in the conventional vibrating and sieving machine in which the motor is directly fixed to the vibrating body in this way, there is a drawback that the power feeding cord to the motor is easily broken in a short period of time due to vibration, and the vibrating element is also used. Since the body and the motor vibrate integrally, the mass of the vibrating part becomes extremely large, mechanical strength is required for the spring or base for supporting it, the manufacturing cost becomes high, and noise is more likely to occur. There was a problem.

期間で折損するおそれがあった。On the other hand, in the drive device for the vibration sieving machine disclosed in Japanese Utility Model Laid-Open No. 54-141068 or Japanese Patent Publication No. 3-21234, the rotation of the motor fixedly mounted on the base is caused by rotation of the belt and the coil spring joint. Although the structure is such that the vibration is transmitted to the vibrator body via a universal joint or the like, in that case, the belt is worn in a short period of time, and the coil spring joint and the universal joint are easily broken, which is a drawback that maintenance is not easy. In addition, real public Sho 55
Since the vibration generator of Japanese Patent No. 6700 also transmits the rotation of the motor by the coil spring joint, it may be broken in a short period of time.

し合うようにしている。Reference numeral 17 denotes a motor which is installed and fixed to the center of the inner bottom portion of the base 1 by a bolt 19 with the rotary drive shaft 18 facing upward. The rotary magnet drive shaft 18 has an upper end on which the permanent magnet disk 14 is mounted.
The permanent magnet plate 20 is fixed so as to face each other through the gap G. The permanent magnets 21 and 21 are fixed to the upper surface of the tip of the permanent magnet board 20, and the permanent magnets 21 and 21 and the permanent magnets 16 and 16 are attracted to each other via the gap G.
