1a, recess 201b, side surface 201c, battery housing 201
Since the case 201 including the d, the + electrode connecting terminal 202, and the − electrode connecting terminal 203 is provided, there is also a problem that the configuration is complicated and the cost is increased.

In view of the above circumstances, the present invention can prevent the occurrence of a momentary interruption phenomenon when an impact is applied from the outside, and is safe in loading a battery, and the cost can be reduced without deformation of members. It is an object of the present invention to provide a battery case and a device that are designed.

[0011]

The battery case of the present invention which achieves the above-mentioned object is a battery case in which a battery is detachably loaded, and a terminal of the loaded battery is brought into contact with and electrically connected to the terminal. And a shock absorbing member to which the contact fitting is fixed.

Further, since the battery case of the present invention includes the shock absorbing member to which the flat plate-like contact fitting is fixed, the shock absorbing member absorbs the shock from the outside. Therefore, it is possible to prevent the occurrence of the instantaneous interruption phenomenon. In addition, the simple configuration can reduce the cost.

The device of the present invention which achieves the above-mentioned object has a battery chamber in which a battery is detachably mounted and a battery lid which can openably close the battery chamber, and the battery is loaded in the battery chamber. In a device that operates by receiving electric power from the battery with the battery cover closed, the battery cover is installed in the battery chamber and the battery in the battery chamber is closed with the battery cover closed. It is characterized by comprising a flat plate-like contact fitting that comes into contact with the terminal and is electrically connected to the terminal, and a shock absorbing member to which the contact fitting is fixed.

In the device of the present invention, since the battery lid is provided with the flat plate-shaped contact fitting, it is safe and safe even when the user touches the contact fitting when loading the battery and the deformation of the contact fitting is prevented. To be done. Further, since the shock from the outside is absorbed by the shock absorbing member, the occurrence of the instantaneous interruption phenomenon is prevented. Therefore, malfunction of the device can be prevented. In addition, the simple configuration can reduce the cost.
