The first shaft member (4) located in the center of the pulsator (3) is rotatably mounted in the main motor (2) formed on the bottom of the outer tub (1) of the washing machine in a forward and reverse direction, and the first shaft member (4). A threaded portion 4A is formed at the outer circumference of the screw, an annular groove 4B and 4C are formed at the upper and lower ends of the threaded portion 4A, and a locking jaw 4D having a stopper function is formed above the groove 4B. Is formed.

Thread portions 5A and 5B are formed on the inner and outer circumferences of the second shaft member 5 which are screwed with the first shaft member 4 described above, and an annular groove 5C is formed on the upper and lower ends of the thread portion 5B of the outer circumference. 5D is formed, and the stopping step 5E of the stopper function is formed above the groove 5C. The first and second elevating bodies 6 and 7 formed of a multi-stage rod which are antenna-folded on the outer peripheral screws 4A and 5B of the first and second shaft members 4 and 5 described above are lifted and lowered. Possibly mounted.

The rotating plate 10 is mounted on the rotating shaft 9 mounted on the sub-motor 8 formed on one side of the outer tub 1 on the bottom of the outer tub 1, and the rotating pin 10 mounted on the rotating plate 10 ( The bottom surface of the 11) is mounted on the upper surface of the rotating plate 12 is formed to be bent to the upper surface is mounted on the inner bottom of the outer tub (1), the fixing pin interlocked with the rotating pin (11) described above and penetrate the inner tank (13) of the washing machine The plate 15 is fixed to the lower end of the 14 and the lower friction member 16 is fixed to the upper end, and the lower friction member 16 is detachably formed with respect to the upper friction member 17.

The second plate member having the first shaft member 4 having the semicircular protrusion 18A formed on the upper surface thereof is fixed to the first shaft member 4 and the engaging hole 19A corresponding to the protrusion 18A being formed. (19) is formed to be raised and lowered relative to the fixing member 20 fixed to the pulsator (3), the second plate member (19) in accordance with the attachment or detachment of the friction member (16) (17) An elastic bias is installed as the elastic member 21 in the fixing member 20 so as to maintain an initial state connecting the power of the main motor 2.

Referring to the operation of the present invention configured as described above, when the sub-motor (8) is driven to rotate the rotating plate 10 through the rotating shaft 9, accordingly the rotating pin 11 mounted on the rotating plate (10) Since the rotary plate 12 is rotated along the curved upper surface and flows in the vertical direction, the rotational motion of the sub-motor 8 is changed to linear motion.

The friction member 16 and 17 are brought into contact with the plate 15 and the fixing pin 14 interlocked with the vertical pin 11 by the pivot pin 11, and the fixing pin 22 fixed to the upper friction member 17. As the second plate member 19 is separated from the first plate member 18 fixed to the above-mentioned first shaft member 4 by means of), the pulsator 3 is connected to the pulsator 3 through the first shaft member 4. Since the driving force of the main motor 2 to be transmitted is cut off, the pulsator 3 is to be stopped.

Since the pulsator 3 stops and only the first shaft member 4 is rotated, as shown in FIG. 3 and FIG. 4, along the threaded portion 4A formed on the outer periphery of the first shaft member 4.
