Technical Examples

The battery housing structure having the battery cavity for housing the battery and the battery cavity lid for closing the opening of the battery cavity, is provided with: the pushing portion for pushing the battery housed in the battery cavity toward the battery cavity lid; the supporting member that supports the battery cavity lid so as to be pivotable about the shaft substantially parallel to the pushing direction of the pushing portion; the battery armature that is provided on the battery cavity lid and is in contact with the electrode of the battery housed in the battery cavity; the slanting part provided on the side, of the battery armature, that comes into contact with the electrode of the battery first when the battery cavity lid is pivoted from the position to open the battery cavity to the position to close the battery cavity. The battery armature pivots while pushing the battery housed in the battery cavity in the direction of the pushing portion. Consequently, the battery cavity lid is easily opened and closed, the battery cavity lid is never lost and the contact resistance of the electrode of the battery can be reduced.
