BATTERY PACK SPACER AND BATTERY PACK

摘要

A spacer (140A) for a battery pack includes an end part (142A) of a first direction. Moreover, a compressibility of a second region to a single battery arrangement direction is greater than that of a first region when the spacer is divided into a first region which occupies half of the space from an end of the first direction to a second direction and also a second region which includes the end (144A) of the second direction; and occupies half to the space from the end part of the second direction to the first direction. As such, contact between the single battery and an electrode terminal is able to be prevented.
