ABSTRACT:
An operation key3is fitted in a guide hole4of an operation section cover2while making contact with support pieces12of a film member 10a. Thus, the support pieces12are pressed, widened, and then bent by an operation section 3b, thus sandwiching the support pieces12between the operation section 3band the guide hole4. Here, the film member 10ahas an elastic force; thus, the operation key3is positioned at a substantially vertical center of the guide hole4by restoring forces of the support pieces12.
