PURPOSE:To prevent a lid and a battery jar from being deposited or adhered while reversely keeping a polarity display provided on an inner lid by providing a projected part on one side of the upper periphery of the battery jar while providing a groove for position control corresponding to the projected part of the battery on one side of the lid back part. CONSTITUTION:A projected part is provided on one side of the upper periphery of a battery jar 1. On the other hand, a groove 9 for position control when fitting into is provided in the position corresponding to the projected part 8 of the battery jar 1 of the back part of a lid 4 while forming the ends 10 with no grooves on the other three sides. Accordingly, in case the lid 4 and the battery jar 1 are fitted into in a state of a reversed polarity display 6, the projected part 8 provided on the battery jar 1 hits on the end 10 of the back part of the lid 4 thus not enabling them to be fitted into while preventing the lid 4 and the battery jar 1 from being deposited or adhered with a reversely fitted polarity display. |
