and a driving unit disposed in the housing and rotating the mover on the basis of a first direction or a second direction perpendicular to the first direction, wherein the protrusions comprise: a first protrusion disposed on the one surface; a second protrusion spaced apart from the first protrusion; and a third protrusion separated from the first protrusion by a distance greater than from the second protrusion, and wherein the housing comprises: a groove in which the first protrusion is seated on an inner surface corresponding to the one surface; a first hole through which the second protrusion passes; and a second hole through which the third protrusion passes, wherein a side surface of the second protrusion is spaced apart from the first hole, and the housing includes a protruding part disposed on a side of the second hole and extending toward the third protrusion. ## Claims ### Claim 1 A camera actuator comprising: a housing; a mover disposed in the housing and including a boss, which protrudes toward the housing, on one surface of the mover; and a driving unit that is disposed in the housing and rotates the mover in a first direction or a second direction perpendicular to the first direction, wherein the boss includes a first boss disposed on the one surface, a second boss spaced apart from the first boss, and a third boss having a larger separation distance from the first boss than from the second boss, wherein the housing includes, in an inner surface corresponding to the one surface, a groove on which the first boss is seated, a first hole through which the second boss passes, and a second hole through which the third boss passes, wherein a side surface of the second boss is spaced apart from the first hole, and wherein the housing includes a protrusion disposed on a side surface of the second hole and extending toward the third boss. ### Claim 2 (depends on 1) The camera actuator of claim 1, wherein the protrusion is disposed at a center of the side surface of the second hole. ### Claim 3 (depends on 2) The camera actuator of claim 2, wherein the protrusion includes extension parts in contact with the third boss, and wherein the extension parts are disposed to be symmetrical to each other with respect to a center of the second hole and overlap each other in the first direction. ### Claim 4 (depends on 3) The camera actuator of claim 3, wherein the extension parts have a curvature and are convex toward the center of the second hole. ### Claim 5 (depends on 1) The camera actuator of claim 1, wherein the mover includes a cap surrounding an end of the second boss and includes a groove on which the second boss is seated. ### Claim 6 (depends on 5) The camera actuator of claim 5, wherein the cap is disposed in the first hole and is spaced apart from a side surface of the first hole. ### Claim 7 (depends on 1) The camera actuator of claim 1, wherein the first hole includes a first inner surface having a side surface disposed on an outermost side from a center of the first hole, a second inner surface in contact with the first inner surface and extending to the center of the first hole, a third inner surface in contact with the second inner surface and inclined toward the mover, and a fourth inner surface closest to the second boss, and wherein the fourth inner surface is disposed closer to the mover than is the side surface of the second hole. ### Claim 8 (depends on 1) The camera actuator of claim 1, wherein a radius of the first hole is greater than a radius of the second hole, and a diameter of the second boss is greater than a diameter of the third boss. ### Claim 9 (depends on 1) The camera actuator of claim 1, wherein the driving unit includes a driving magnet and a driving coil, wherein the driving magnet includes a first magnet, a second magnet, and a third magnet, wherein the driving coil includes a first coil, a second coil, and a third coil, wherein the first magnet and the second magnet are arranged to be symmetrical to each other on the mover in the first direction, wherein the first coil and the second coil are arranged to be symmetrical to each other between the housing and the mover in the first direction, wherein the third magnet is disposed on a bottom surface of the mover, and wherein the third coil is disposed on a bottom surface of the housing. ### Claim 10 (depends on 7) The camera actuator of claim 7, wherein the first inner surface is the surface with the largest separation distance from the center of the first hole. ### Claim 11 (depends on 7) The camera actuator of claim 7, wherein the third inner surface is an inclined surface in contact with the second inner surface and the fourth inner surface. ### Claim 12 (depends on 7) The camera actuator of claim 7, wherein the fourth inner surface has the smallest distance from the center of the first hole among the side surfaces of the first hole. ### Claim 13 (depends on 7) The camera actuator of claim 7, wherein the fourth inner surface is at least partially spaced apart from the second boss. ### Claim 14 (depends on 1) The camera actuator of claim 1, wherein the protrusion is located in a center of the side surface of the second hole. ### Claim 15 (depends on 1) The camera actuator of claim 1, wherein the side surface of the second hole is an exposed surface exposed by the second hole. ### Claim 16 (depends on 1) The camera actuator of claim 1, wherein the third boss is not in contact with a bottom surface of the second hole. ### Claim 17 (depends on 1) The camera actuator of claim 1, wherein the protrusion supports the third boss. ### Claim 18 A camera actuator comprising: a housing; a mover disposed in the housing and including a boss, which protrudes toward the housing, on one surface of the mover; and a driving unit that is disposed in the housing and rotates the mover in a first direction or a second direction perpendicular to the first direction, wherein the boss includes a first boss disposed on the one surface, a second boss spaced apart from the first boss, and a third boss having a larger separation distance from the first boss than from the second boss, wherein the housing includes, in an inner surface corresponding to the one surface, a groove on which the first boss is seated, a first hole through which the second boss passes, and a second hole through which the third boss passes, wherein a side surface of the second boss is spaced apart from the first hole, and wherein the housing includes a protrusion disposed on a side surface of the second hole and disposed in contact with the third boss.
