A battery chamber comprising: a claw mechanism for a battery including: a movable member that is movable in insertion and removal directions of a battery, and abuts a front face of the battery in the insertion direction when the battery is inserted and completely loaded; an urging member that urges the movable member in the removal direction; and a stopper having: a locking claw that locks a back face of the battery from behind in the insertion direction when the battery is completely loaded, wherein in a case where the battery is inserted, and the movable member is pressed and moved in the insertion direction by the battery, and then an interval in the insertion direction between the movable member and the locking claw becomes a length of the battery in the insertion direction, the locking claw moves from an evacuation position of the locking claw where the locking claw does not interfere with the battery when the battery is inserted to a locking position of the locking claw where the locking claw locks the back face of the battery from behind in the insertion direction when the battery is completely loaded.
