a lengthwise moving member coupled to the pair of electrode lead support members and coupled to the lengthwise rotary shaft to move along the lengthwise rotary shaft when the lengthwise rotary shaft rotates so that the pair of electrode lead support members are moved,

wherein the lengthwise moving member is provided in a pair so that the pair of lengthwise moving members are respectively coupled to the pair of electrode lead support members, and

the pair of lengthwise moving members move along the lengthwise rotary shaft so that the pair of electrode lead support members move closer to each other or move away from each other.

2. The battery transporting apparatus according to claim 1 ,

wherein the frame member includes:

a first frame disposed in the length direction of the battery cell;

a second frame spaced apart from the first frame to form a space between the first frame and the second frame and disposed in the length direction of the battery cell;

a third frame configured to connect a first end of the first frame to a first end of the second frame; and

a fourth frame configured to connect a second end of the first frame to a second end of the second frame at a location opposite to the third frame,

wherein the lengthwise rotary shaft is disposed in the length direction of the battery cell inside the space between the first frame and the second frame.

3. The battery transporting apparatus according to claim 2 , further comprising:

a lengthwise rotating member coupled to the lengthwise rotary shaft to rotate the lengthwise rotary shaft,

wherein a first side of the lengthwise rotary shaft is coupled to the fourth frame and a second side of the lengthwise rotary shaft is fixed to the lengthwise rotating member, and

the lengthwise rotary shaft rotates in association with the rotation of the lengthwise rotating member.

4. The battery transporting apparatus according to claim 1 ,

wherein the lengthwise rotary shaft includes:

a lengthwise first thread portion coupled to a first lengthwise moving member among the pair of lengthwise moving members;

7. The battery transporting apparatus according to claim 6 ,

wherein the lengthwise connector guide includes:

a lengthwise first guide having an inner surface of a regular hexagonal shape; and

a lengthwise second guide having an inner surface of a circular shape, and

wherein the lengthwise connector includes:

a lengthwise first outer surface portion having an outer surface of a regular hexagonal shape to correspond to the lengthwise first guide; and

a lengthwise second outer surface portion having an outer surface of a circular shape to correspond to the lengthwise second guide.

8. A battery transporting apparatus, comprising:

a frame member configured to support a battery cell;

a pair of electrode lead support members movably mounted to the frame member to be adjustable in a length direction of the battery cell among length, width and thickness directions of the battery cell and configured to support electrode leads of the battery cell, respectively;

a cell support member movably mounted to the frame member to be adjustable in the thickness direction of the battery cell and configured to support a center portion of the battery cell;

a frame supporting adjustable member coupled to a lower side of the frame member to be adjustable in the width direction of the battery cell;

a thickness-wise rotary shaft coupled to the frame member; and

a thickness-wise moving member coupled to the cell support member and coupled to the thickness-wise rotary shaft, the thickness-wise moving member being configured to move along the thickness-wise rotary shaft when the thickness-wise rotary shaft rotates so that the cell support member is moved,

wherein the cell support member includes:

a first support member having a plurality of first support portions spaced apart from each other at preset intervals, each of the plurality of first support portions having a hollow; and

a second support member having a plurality of second support portions spaced apart from each other at preset intervals,

wherein the second support member is smaller than the first support member, and

wherein the plurality of second support portions are inserted into the hollows of the plurality of first support portions to move through the hollows.

9. The battery transporting apparatus according to claim 8 ,

wherein each of the plurality of first support portions includes:

a first straight section formed vertically;

a second straight section spaced apart from the first straight section and formed vertically; and

a third straight section configured to connect the first straight section and the second straight section,
