Description of the Related Art In a device using a battery as a power source, for example, an electronically controlled camera, a battery is mounted as a power source for a drive mechanism and control circuit of each section. Generally, when mounting a battery on a device, the battery is placed in a battery chamber provided in the device and the lid is closed to fix the battery. The battery compartment is provided with battery contact pieces that come into contact with the positive and negative electrodes of the battery, and power is supplied to each drive mechanism, circuit, etc. via the battery contact pieces. A certain amount of load (contact pressure) is applied between the battery contact piece and the electrode of the battery to ensure the contact. Although it depends on the usage of the device, generally, the load between the electrode of the battery and the contact piece needs to be set to a high value in consideration of the self-weight of the battery and shocks during use. However, if the load is too large, the battery contact pieces will be urged in a direction to press the batteries against each other, which makes it difficult to install the battery, or when installing the battery in the battery chamber There was a case where a large force was applied to the armature and the armature was bent.
