ｂから突出させるようにすることができる。When the battery pack is placed on the placing portion 1a, the battery charger having the above-mentioned structure pushes the contact portion 7b of the battery connecting terminal 7 whose battery pack terminal projects from the terminal hole 1b as described above. By doing so, connection for charging is performed. However, in this case, the pack terminal is the contact portion 7
Since b is not pushed below the upper end opening of the terminal hole 1b, the tip of the contact 7b does not reach the stopper 6a. Further, when the battery pack is not placed on the placing portion 1a, the upper portion of the placing portion 1a is open, so that a thin object such as a ballpoint pen accidentally enters the terminal hole 1b and contacts. There is a risk of pushing the portion 7b. However, in the case of the present embodiment, even if the contact portion 7b of the battery connection terminal 7 is pushed into the inside of the terminal hole 1b by being pushed by a thin object, the tip of the contact portion 7b is further pushed into the stopper 6a. Since they come into contact with each other, they do not completely enter the inside of the outer casings 1 and 2, and when the pressure is released, the terminal hole 1 is securely held by elasticity.
It can be made to project from b.
