<P>PROBLEM TO BE SOLVED: To maintain the connection strength of a battery holder while avoiding an increase in its size. <P>SOLUTION: There are included a first holding member 27A for holding a battery cell 26 accommodated in a housing space 28 of a battery holder 22 so as not to fall off from the housing space 28 and a second holding member 27B for holding a battery cell 26 accommodated in a housing space 28 of a battery holder 22 so as not to fall off from the housing space 28, the latter being provided on a second coupling face 23B which is an end face on the other side of the former. In order for a plurality of the battery holders 22 to be coupled together in the longitudinal direction of the battery cell 26, a first coupling face 23A and the second coupling face 23B of each battery holder 22 are contacted as a connecting interface, while the first holding member 27A is protruded so as to be separate in plurality on the first coupling face 23A and the second holding member 27B is disposed at a position on the second coupling face 23B differing from the position at which the first holding member 27A is disposed, whereby the first holding member 27A and the second holding member 27B are contacted in such a way that the former does not overlap the latter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
