The present invention relates an actuator including a housing, a drive unit installed in the housing and provided with a rotatable shaft, a bearing part installed in the housing to rotatably support the shaft at different positions, at least one bearing part included in the bearing part being fixed to the housing, and a gear unit accommodated in the housing, the gear unit being rotated about different axes rotational power transmitted thereto from the shaft.

Actuator and electronic device having the same

The invention relates generally to a step actuator, in which a lead screw coupled with a screw thread formed in a nut member is installed in a rotor magnet and moves back and forth in an axial direction responding to a rotation of the rotor to transmit power in an axial direction. A cylindrical bearing for rotatably supporting the nut member is disposed at an upper part of the nut member and integrally formed therewith, to fundamentally remove a gap in the axial direction in the coupled area between the cylindrical bearing and the nut member, thereby significantly reducing the feeding error of a rotator in the axial direction when the lead screw moves back and forth in the axial direction, and reducing the number of parts to be assembled to lower the material cost and the labor cost for assembly.
