Abstract
The present application is intended to prevent an excessive pressure from acting on a battery due to an expansion of the battery. A battery accommodating device having a battery chamber, which is formed in a housing and in which a battery is accommodated, the battery chamber being covered with a cover member, and has a lock part which fixes the housing and the cover member and a lock release part which unlocks the lock part when the battery has expanded. An output device includes a lock member which, while the cover member is being mounted to the housing, engages with a part of the cover member to prevent separation of the cover member and a displacement transmitting member, which transmits an expansive displacement of a battery to the lock member and releases the engagement of the lock member with a part of the cover member.
