Abstract: Provided is a battery housing device that can satisfactorily protect a battery terminal and housing section terminal. A housing section of a battery housing device has an opening through which a battery can be inserted and removed, and a housing space in which the battery can be removably housed via the opening. The relative position of the housing section terminal with respect to the housing section is fixed, and the housing section terminal can be brought into contact with and connected to a battery terminal. A portable part can support the battery and is movable in relation to the housing section between a connected position at which the housing section terminal and the battery terminal are connected and a non-connected position at which the housing section terminal and the battery terminal are not connected. A regulating part releasably regulates movement of the portable part from the non-connected position to the connected position.

Abstract: Provided is a battery storage apparatus having improved switching operability between the locked state and the unlocked state of a lock. In the battery storage apparatus, a battery can be detachably stored in a storage space of a storage part, and the battery can be fixedly held in a holding position/location of the storage space. A portable part can support the battery and can move between the holding position and an insertion/extraction position within the storage space. In the portable part the battery is inserted and extracted at the insertion/extraction position. The lock enters a locked state that fixedly holds the battery to the storage part when the portable part is in the holding position, and enters an unlocked state that releases the fixed holding of the battery to the storage part when the portable part is in the insertion/extraction position.
