Belt 3. Meanwhile, Ratchet 7 will be braked by Pawl 8 through the action force of the spring, and
the movement will be transferred to Center Gear 9, and then be retarded and transferred to
Tie-rod 10 through a planetary gear mechanism consisting of Center Gear 9, Planet Gear 10 and
Spin Shaft 4 (inner gear), then Tie-rod 10 is connected to Pulsator 12 via a spline shaft.Therefore,
Pulsator 12 will move along with the clockwise and counterclockwise rotation of the Motor 1.
During spinning, the rotation of Motor 1 is transferred to Follower 5 from Drive Wheel 2 through
Belt 3. Meanwhile, Pawl 8 will leave Ratchet 7 by the action of the puller. Clutch Reed 6is twisted
tightly on the down part of Spin Shaft 4. The Spin tub 13 is connected to Spin shaft 4 with flange.
The movement of Motor 1 will be retarded by V-belt, and then transferred to Spin shaft 4 and
make the Spin tub 13 to spin.
