A second surface 31a having a first step in the optical axis direction with reference to 51a, and an inclined surface 31b having a preset angle with respect to the first surface 51a or the second surface 31b. can

For example, the inclined surface 31b may be formed at the edge of the housing 140 . In addition, the inclined surface 31b may be in contact with the second surface 31a and may extend from the second surface 31a.

In addition, the housing 140 may further include a third surface 51c having a second step in the optical axis direction with respect to the first surface 51a. For example, the first step and the second step may be the same, but the present invention is not limited thereto, and may be different from each other in another embodiment.

For example, the second surface 31a may be a horizontal surface parallel to the first surface 51a, and the third surface 51c may be parallel to the first surface 51a, but is not limited thereto. In the example, both may not be parallel to each other.

For example, the inclined surface 31b may be spaced apart from the first surface 51a and inclined downward with respect to the second surface 31a, which is a horizontal surface.

This is to secure a space in which the hole 147 is to be formed in the second surface 31a and to prevent the inclined surface 31b from spatially interfering with the cover member 300 .

For example, the ratio (L2:L1) of the length L2 of the inclined surface 31b to the length L1 of the second surface 31a may be 1:1.03 to 1:1.5. When the divided value (L1/L2) is less than 1.03, sufficient space to form the hole 147 in the second surface 31a cannot be secured, and when the divided value (L1/L2) is greater than 1.5, the cover member 300 Spatial interference between and the housing 140 may occur.

However, in another embodiment, the length L2 of the inclined surface 31b may be greater than the length L1 of the second surface 31a.

For example, the first surface 51a of the corner portions 142-1 to 142-4 may be positioned higher than the second surface 31a and the third surface 51c. This is to prevent the adhesive or damper from flowing into the third surface 51c when the adhesive is injected into the adhesive injection grooves 146a and 146b to be described later or the damper is applied to the second surface 31a.

For example, the guide protrusion 144 of the housing 140 may be disposed on the third surface 51c of each of the corner portions 142-1 to 142-4, but is not limited thereto.

For example, the first coupling portion 143 of the housing 140 may be disposed on the first surface 51a of the corner portions 142-1 to 142-4 of the housing 140 and may have a protrusion shape, It is not limited thereto, and in another embodiment, it may be a groove or a planar shape.

For example, the at least one adhesive injection groove 146a and 146b may be disposed on the second surface 31a of the corner portions 142-1 to 142-4 of the housing 140 . For example, the at least one adhesive injection groove (145a, 146b) may be in contact with the first surface (51a) of the corner parts (142-1 to 142-4) of the housing 140, but is not limited thereto.

When the diameter of the adhesive injection grooves 146a and 146b is less than 0.3 mm, the size is small and the adhesive may not be smoothly injected, and when it exceeds 0.8 mm, the size is too large to form the hole 147 of the housing 140. Can't get enough space to do it.

For example, the through-holes 46a and 46b may be provided in part of the bottom and part of the side of the at least one adhesive injection groove 145a and 146b. This is so that the adhesive injected into the adhesive injection grooves 145a and 145b is slowly injected into the seating portion 141a through the through holes 46a and 46b, so that the adhesive can be uniformly applied to the seating portion 141a. .

Two adhesive injection grooves 146a and 146b spaced apart from each other may be disposed in each of the corner portions 142-1 to 142-4 of the housing 140, and between the two adhesive injection grooves 146a and 146b. A stepped, protrusion or protrusion 47 protruding from the second surface 31a in the optical axis direction may be disposed. The protrusion 47 may serve to allow the adhesive to be uniformly injected into the two adhesive injection grooves 146a and 146b.

For example, in order to avoid spatial interference with the support members 220-1 to 220-4, the diameter of the uppermost end of the hole 147 of the housing 140 may be 0.4 mm to 0.6 mm, and the hole ( 147) may have a diameter of 0.3mm to 0.4mm at the lowermost end.

For example, the hole 147 of the housing 140 may be disposed to be positioned outside the adhesive injection grooves 146a and 146b.

The hole 147 of the housing 140 may be formed in at least one of the second surface 31a and the inclined surface 31b.

For example, the hole 147 of the housing 140 may be formed over the second surface 31a and the inclined surface 31b of the housing 140 .

For example, a portion of the hole 147 of the housing 140 may be formed on the second surface 31a, and the remaining portion may be formed on the inclined surface 31b.

For example, the hole 147 of the housing 140 may be positioned between the edge of the upper surface 51 of the corner portions 142-1 to 142-4 and the stopper 145 .

In general, in order to implement a low-height Renjae driving device, the thickness (length in the optical axis direction) of the protrusion 71a of the housing 140 may be reduced, and thus the strength of the protrusion 71a may be weakened.

However, the thickness (length in the optical axis direction) of the protrusion 71a according to the embodiment may be reduced in a direction from the center of the housing 140 to the corner portions 142-1 to 142-4 of the housing 140 . have.

Since the length L1 of the magnets 130-1 to 130-4 decreases from the center of the housing 140 toward the corner portions 142-1 to 142-4 of the housing 140, the sensing magnet Magnetic field interference between 180 and the magnets 130 - 1 and 130 - 4 and magnetic field interference between the balancing magnet 185 and the magnets 130 - 1 and 130 - 4 may be reduced.
