Document Type and Number:
WIPO Patent Application WO/2015/119381
Kind Code:
A1
Abstract:
A reciprocating rotational motion device and a cleaning device including the same are disclosed. The reciprocating rotational motion device, according to one embodiment of the present invention, comprises: a motor part which generates axial torque; an eccentric shaft part of which one end is coupled to the motor part and the other end has an eccentric shaft so as to axially rotate by the torque generated in the motor part; ring part which is coupled to the eccentric shaft so as to enable the ring part to idle and move along the trajectory of the eccentric shaft during axial rotation of the eccentric shaft part; and a cam part having the ring part interposed between a pair of protrusion pieces that protrude so as to face each other on one side thereof, and carrying out reciprocating rotational motion on a reciprocating rotation axis formed at the center thereof when the ring part is moved.
