Abstract

PROBLEM TO BE SOLVED: To facilitate the removal of separation type battery pack used for a cellular phone and the like for improving operability and appearance design. SOLUTION: A projection part to be engaged in a groove part in a head part of a battery pack 50 is arranged in a cellular phone main body 10. An elastic body is arranged in the groove part. A recess part to be engaged in a hooking part in the bottom part of the battery pack 50 is arranged in a cellular phone main body 10. When the groove part in the head part of the battery pack 50 is fitted and pushed onto the projection part of the cellular phone main body 10 after the hooking part in the bottom part of the battery pack 50 is engaged in the recess part of the cellular phone main body 10, a claw of a sliding knob 20 is engaged in the battery pack 50 and is fixed. Because of deformability of the elastic body in the groove part in the head part of the battery pack 50, the claw is held stably. When the sliding knob 20 is pulled, the battery pack 50 is pushed up by means of the elastic body in the groove part, and the battery pack 50 is lifted while using the hooking part in its bottom part as a rotation support point so that the battery pack 50 can be removed with ease.
