Referring to <FIG> and <FIG>, a loosening prevention portion <NUM> may be inserted into the hole <NUM> of the machined coupling portion <NUM> in a top-down direction. In this case, the groove of the loosening prevention portion <NUM> may be disposed at a position corresponding to the hole <NUM> of the coupling portion <NUM> of the camera module <NUM>. In another embodiment of the present invention, the loosening prevention portion <NUM> is described as an example of a donut shape, but is not limited thereto and may be variously modified, such as a rectangular plate of the loosening prevention portion <NUM>.

Referring to <FIG>, the elastic member <NUM> is disposed on the support portion <NUM> of the bracket <NUM>, and the view angle adjustment member <NUM> is disposed on the elastic member <NUM> and the support portion <NUM>. Thereafter, by screw-coupling the view angle adjustment member <NUM> to the coupling portion <NUM> of the camera module <NUM>, the view angle of the camera module <NUM> with respect to the bracket <NUM> may be adjusted.

<FIG> is a perspective view of a camera angle adjustment device according to another embodiment of the present invention. <FIG> is an enlarged view of part C of <FIG>. <FIG> is a cross-sectional view of a partial configuration of a camera angle adjustment device according to another embodiment of the present invention.

Referring to <FIG> and <FIG>, the camera adjustment device <NUM> according to another embodiment of the present invention may include a bracket <NUM>, a camera module <NUM>, a view angle adjustment member <NUM>, an elastic member <NUM>, and a loosening prevention portion <NUM>, but may be implemented excluding some of the configurations, and additional configurations are not excluded.

The second sidewall <NUM> of the support portion <NUM> of the bracket <NUM> may include grooves <NUM> and <NUM>. The grooves <NUM> and <NUM> may include two grooves <NUM> and <NUM>. The grooves <NUM> and <NUM> may be formed to be spaced apart from the second opening <NUM>. One of the two grooves <NUM> and <NUM> is formed in the central region of the second sidewall <NUM> located on one side of the second opening <NUM>, and the other may be formed in a central region of the second sidewall <NUM> located on the other side of the second opening <NUM>. The grooves <NUM> and <NUM> may not be overlapped with the protrusions <NUM> and <NUM>. Through the grooves <NUM> and <NUM>, the protrusions <NUM> and <NUM> can be easily molded.

<FIG> and <FIG> are views showing a manufacturing process of a camera angle adjustment device according to another embodiment of the present invention.

Referring to <FIG> and <FIG>, a process of forming the projections <NUM> and <NUM> of the camera angle adjustment device <NUM> according to another embodiment of the present invention will be described.

Claim 1:
A camera device, comprising:
a bracket (<NUM>);
a camera module (<NUM>) coupled to the bracket (<NUM>) so as to be rotatable about a first axis;
a view angle adjustment member (<NUM>) comprising a first portion coupled to the bracket (<NUM>) and a second portion coupled to the camera module (<NUM>); and
an elastic member (<NUM>) disposed on the bracket (<NUM>) to contact the first portion of the view angle adjustment member (<NUM>) with the bracket (<NUM>), wherein the view angle adjustment member (<NUM>) comprises a body (<NUM>), a thread (<NUM>) formed in the second portion and an end portion (<NUM>),
characterized in
a locking portion (<NUM>) protruding from the first portion, and
wherein the end portion (<NUM>) and the locking portion (<NUM>) of the view angle adjustment member (<NUM>) are spaced apart,
wherein the elastic member (<NUM>) comprises a first region (<NUM>) disposed between the end portion (<NUM>) and the locking portion (<NUM>), and a second region (<NUM>) being formed by being bent relative to the first region (<NUM>) and disposed between the end portion (<NUM>) and one surface of the bracket (<NUM>),
wherein the bracket (<NUM>) comprises a support portion (<NUM>) in which the elastic member (<NUM>) and the end portion (<NUM>) are disposed and supported, and
wherein the support portion (<NUM>) comprises a first sidewall (<NUM>) disposed between the camera module (<NUM>) and the first portion of the view angle adjustment member (<NUM>), a second sidewall (<NUM>) facing the first sidewall (<NUM>), and a third sidewall (<NUM>) and a fourth sidewall (<NUM>) connecting the first sidewall (<NUM>) and the second sidewall (<NUM>).
