PROBLEM TO BE SOLVED: To improve reliability of a mechanism consisting of a lid member, a lock claw, and an assisting SP by avoiding unexpected troubles such as a fall of a battery even in the case of vibration or shock. SOLUTION: The lock mechanism, comprising a lid member 4, a lock claw 2 movable between a locking position and a release position, and an assisting SP biasing the lock claw toward a direction of the locking position, corrects a contacting angle of a lock part in contact with the lid member 4 by deforming the lock claw further toward the locking position than in an unloaded state by the biasing force of the assisting SP 3.
