た。尚、６は軸受、７はパツキングを示す。 1 is a motor, 2 is a motor holder, and 3 is a stirring tank. The holder 2 has a cylindrical shape, and its lower end is fixed on the lid 3a of the stirring tank 3, and its upper end has a locking protrusion 2a. is formed to protrude inward, and the motor 1 is fixed to the upper surface of the locking protrusion 2a. In the motor holder 2, a harmonic drive is connected between the drive shaft 1a, which is the rotating shaft of the motor 1, and the blade shaft 4a, which is supported through the center hole of the lid 3a and has a stirring blade 4 attached to its lower end. They were connected by a type reducer 5. The speed reducer 5 includes a wave generator 5a, a flex spline 5b, and a circular spline 5c. The spline 5b is a thin-walled cylindrical elastic metal body whose inner circumferential surface is in sliding contact with the ball bearing 5e, and its outer circumferential surface is notched with teeth, and the circular spline 5c is a cylindrical rigid body whose inner circumferential surface is in sliding contact with the ball bearing 5e. The teeth of the same pitch as the flexspline 5b are knurled, and the number of teeth is n (for example, 2) more than the number of teeth of the flexspline 5b. Then, the cam 5d of the wave generator 5a is connected to the drive shaft 1.
a, and the wing shaft 4a is fixed to the cup-shaped lower surface of the circular spline 5c,
Further, the flexspline 5b is formed into a cylindrical shape with a bottom, and a flange 5f is formed at the upper end of the flexspline 5b, and the flexspline 5b is sealed and fixed to the locking protrusion 2a at the flange 5f. Note that 6 indicates a bearing and 7 indicates packing.

て同一方向に回転し、前記液体を撹拌する。 Thus, when a predetermined liquid is put into the stirring tank 3, the inside of the stirring tank 3 is brought into a high pressure or vacuum state, and the motor 1 is driven, the blade shaft 4a, that is, the stirring blade 4 is moved relative to the drive shaft 1a of the motor 1. It is reduced in speed by a reduction ratio of i and rotates in the same direction, stirring the liquid.
尚、フレクスプライン５ｂの歯数Zf、サーキユ
ラ・スプライン５ｃの歯数Zc（＝Zf＋ｎ）とする

Since the flexspline is tightly fixed to the lower surface of the locking protrusion of the motor holder, the flexspline acts as a seal wall, eliminating the need for a shaft seal and making it possible to maintain high pressure or vacuum in the stirring tank, for example. Since the wall is formed from one component of the reducer, the structure is simple, it does not take up much space, and it is safe.Furthermore, since the reducer does not use magnets, there is no slippage caused by high loads as in the conventional case. It has various effects.
