Claims

[Scope of utility model registration request]

Providing a reverse-insertion prevention member near a contact that conducts contact with the positive electrode protrusion of the battery, which prevents contact conduction between the two when the negative electrode side of the battery faces the contact;
A reverse insertion prevention mechanism for a battery, characterized in that the reverse insertion prevention member is movable in the radial direction of the positive electrode projection of the battery.
