Abstract

A battery holder includes storage chamber for storing a battery. The storage chamber includes: opening end surface through which battery can be taken in or out; and upper surface section, lower surface section, and first and second side-surface sections (opposing each other) for holding the battery. Projection is formed on the inner wall of first side-surface section at a portion including the end on the opening end surface side. Outward deformable flexible section is formed on second side-surface section at a portion including the end on the opening end surface side. Slit that extends from third side-surface section opposite to the opening end surface toward the opening end surface and stops at the position corresponding to a part of the battery is formed in upper surface section and/or lower surface section. The end of the flexible section is located closer to the third side-surface section than the projection.

First claim

1 . A battery holder comprising:
a storage chamber for storing a button battery,
wherein the storage chamber including:
an opening end surface through which the button battery is taken in or out while being led by a side surface of the button battery; and
an upper surface section, a lower surface section, a first side-surface section, and a second side-surface section for holding flat surfaces and a side surface of the button battery, the first side-surface section and the second side-surface section opposing each other,

wherein a projection projecting toward an inside of the storage chamber is formed on an inner wall of the first side-surface section at a portion including an end on an opening end surface side,
a flexible section deformable toward an outside of the storage chamber is formed on the second side-surface section at a portion including an end on the opening end surface side,
a slit is formed in at least one of the upper surface section and the lower surface section, the slit extending from a third side-surface section opposite to the opening end surface toward the opening end surface, and extending to a position corresponding to a part of the button battery,
an end of the flexible section on the opening end surface side is located closer to the third side-surface section than the projection in an extending direction of the flexible section.

2 . The battery holder according to claim 1 , wherein
the flexible section is configured so that a pair of cutouts extending from the end on the opening end surface side toward the third side-surface section are formed in the second side-surface section.

3 . The battery holder according to claim 1 , wherein
the storage chamber further includes an elastic piece for pressing at least one of the flat surface and the side surface of the button battery.

4 . The battery holder according to claim 1 , wherein
a width of the slit is narrower than a diameter (5.6 mm) of a test finger defined by International Electrotechnical Commission (IEC).

5 . A portable lighting apparatus integrally comprising:
the battery holder according to claim 1 ; and a lighting unit coupled to the storage chamber of the battery holder and using the button battery as a power source, wherein the storage chamber is detachably mounted on a holding unit disposed at an end of a neck strap.

6 . The battery holder according to claim 1 , wherein
the slit is located at the second side-surface section from a center line passing a center of the button battery and being parallel with the first side-surface section and the second side-surface section.
