Actuator for driving zoom

An actuator for a driving zoom, comprising:

• a first carrier, comprising
• a first mounter configured such that a first lens assembly is mountable on the first mounter,
• a first supporting part configured to extend from a first side of the first mounter toward a first direction,
• a first guider configured to extend from a second side of the first mounter toward the first direction, the second side being opposite to the first side;
• and
• a second carrier, comprising
• a second mounter configured such that a second lens assembly is mountable on the second mounter,
• a second supporting part configured to extend from a second side of the second mounter toward a second direction, the second direction being opposite to the first direction, and
• a second guider configured to connect to extend from a first side of the second mounter toward the second direction,
• wherein the first direction and the second direction are defined along an optical axis,
• wherein normals of the first side and the second side of the first mounter, which is aligned with the optical axis, or normals of the first side and the second side of the second mounter, which is aligned with the optical axis, are oriented toward a third direction and a fourth direction, respectively, wherein the third direction and the fourth direction are perpendicular to the optical axis and opposite to each other,
• wherein a first joint structure formed by the first mounter and the first supporting part is configured to define a first passage into which the second guider is inserted,
• wherein a second joint structure formed by the second mounter and the second supporting part is configured to define a second passage into which the first guider is inserted,
• wherein the first guider and the second guider respectively includes a first damper and a second damper, the first damper and the second damper being configured to limit a separation distance between the first carrier and the second carrier.
