PURPOSE: To make the connecting work easy and reduce the size by providing a wire connecting part for a tooth rest spring on the outer part of the inner case, fixing the tooth rest spring to the inner case, and then connecting an external wire thereto.
CONSTITUTION: A case 10 is made exposed in an important point of the outer shell 20 covering the inner case 10 to form a plug tooth inserting port 11. An external wire 30 is pulled out from the shell 20, one end part of said wire 30 is connected to the tooth rest spring within the case 10 in the wire connecting part 34, and the other end part is connected to a plug 31. The connecting part 34 is formed in the part to be buried within the shell 20 in the outside of the case 10. The connecting part 34 is composed of a crump-style terminal fixing the wire 30 by caulking, and the direction of the wire 30 toward the connecting part 34 is almost in accord with the direction of the center line of the connecting part 34. Hence, no space for receiving the wire 30 is required, so that the size is reduced as the whole. As the electric wire 30 is never bent, any unnecessary elastic force does not act, and the connecting work is made easy.
