At this time, the moving member 730 is moved by the rotation of the height adjusting member 710, and accordingly, the first and second moving shafts 706 and 707 move together, and the first and second links 701 and 702 As the crossing angle of is adjusted, the first bracket 300 and the second bracket 320 may be moved to approach each other or move away from each other.

That is, according to the rotation of the height adjustment member 710, the base member 211 rises and falls, and through this, the battery can be mounted regardless of the height of the battery. For example, when the base member 211 is raised to the maximum, a battery having a height standard of about 100 to 110 mm can be accommodated, and when the base member 211 is lowered to the maximum, a height of about 200 mm to 220 mm Batteries with specifications can be accommodated.

In the cassette assembly 9 for height adjustment of the present invention, the height of the base member 211 may be adjusted according to the rotation direction of the height adjustment member 710, and accordingly, batteries of various standards having different heights may be mounted.

Accordingly, in one embodiment of the present invention, the battery tray may drive one or more of a width adjustment unit, a thickness adjustment unit, and a height adjustment unit, and thus accommodate batteries of various standards related to width, thickness, and height. Therefore, it is possible to expand the application range according to the standard of the battery.

Although an embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiment presented in the present specification, and those skilled in the art who understand the spirit of the present invention can add components within the scope of the same idea It will be possible to easily propose other embodiments by changing, deleting, adding, etc., but it will be said that this is also within the scope of the present invention.
