That is, the coupling protrusion 112 is approximately
It can protrude from the inner wall part 111 in a character shape.

At least one coupling protrusion 112 may be formed. However, since the coupling protrusion 112 serves to fix the second cover 140, if only one coupling protrusion 112 is formed, the second cover 140 may not be firmly coupled to the housing 110. Furthermore, when three or more coupling protrusions 112 are formed, the structure of the coupling site may become unnecessarily complicated. Therefore, it may be preferable that two coupling protrusions 112 be formed at positions facing each other inside the inner wall part 111.

A side surface of the housing 110 may protrude from one side of the housing 110 to one side. In other words, one side of the housing 110 may further protrude downward from the lower surface of the housing 110 . The first cover 130 may be seated inside a portion of the side surface of the housing 110 that protrudes from one side of the housing 110 .

The flange 142 can be formed larger than the first opening 01. When the second cover 140 passes through the first opening 01 of the first cover 130 and is coupled to the housing 110, the flange 142 of the second cover 140 may contact the stepped portion 132 of the first cover 130. Accordingly, the first cover 130 can be fixed to the housing 110 by the second cover 140.

One surface of the flange 142 is radially uneven. A plurality of unevenness can be formed. When a user rotates the second cover 140 to couple it to the housing 110 or unlock it, the unevenness may serve to increase frictional force and facilitate the rotation of the second cover 140.

Specifically, the user can attach or detach the second cover 140 while holding the handle of the battery 100. At this time, since the second cover 140 is combined or separated at the lower part of the housing 110, the user can operate the second cover 140 without being able to see it. The unevenness plays a role in allowing the user to easily locate the second cover 140 by touching it with the user's hand, and increases the frictional force between the user's hand and the second cover 140 . It can serve to facilitate rotation.

The second cover 140 may include a locking protrusion 143 . The locking protrusion 143 can protrude radially outward from the flange 142. A portion of the locking protrusion 143 may protrude from the other side of the flange 142 to the other side.
