案の実施による効果には多大なものがある。(Effect of the invention) According to the invention, the battery contact piece can be engaged and held by the locking protrusion and the connecting piece used to connect the base plate and the dust cover, so that the battery contact piece can be held. There is no need to separately provide a clamping part to hold the battery, and the battery contact piece only needs to be inserted into a notch in the base plate, so it is easy to assemble.
This is advantageous for automatic assembly. Furthermore, since the battery contact piece is exposed outside the frame, the battery contact piece can be easily used as an external terminal. There are many benefits from implementing this invention.
