Abstract
A dry cell accommodating device includes a dry cell chamber, a cover and a dry cell holder. When a plurality of larger dry cells, for instance, size 'AA' dry cells are accommodated, they are fitted into the interior of the dry cell chamber without any necessity for the dry cell holder. When a plurality of smaller dry cells, for instance, size 'AAA' dry cells are accommodated, they are first held by means of the dry cell holder and the latter is then fitted into the dry cell chamber together with the dry cells. The device is provided with a mechanism for inhibiting an occurrence of incorrect fitting of the dry cell holder. The mechanism comprises a plurality of projections on the bottom of the dry cell chamber and a plurality of recesses formed at the lower part of the dry cell holder to be fitted over the projections when the dry cell holder is oriented in the correct direction. Further, the device is provided with another mechanism for inhibiting incorrect fitting of smaller dry cells. The last-mentioned mechanism comprises a pair of projections formed on one side of the dry cell holder and an insulation ring fitted around the outer periphery of the end part of a terminal rod disposed on the other side of the holder.
