<P>PROBLEM TO BE SOLVED: To provide a structure that gives a feeling of clicking at an equal level to or higher level than that of conventional products and can be easily regulated for the rotation range even if a register has a small dimension in a height direction. <P>SOLUTION: A leaf spring portion is formed by offset in an axial direction inside the tooth portion of a dial knob, and a projection protruding from the leaf spring portion outward in a radial direction is formed in the leaf spring portion, in such a manner that when the dial knob is rotated, the projection interferes with an interference projection formed as protruding from a retainer. Even if the leaf spring portion slightly moves by the pressure upon operating the dial knob, the projection reliably interferes with the interference projection, thereby the sense of clicking is not degraded. <P>COPYRIGHT: (C)2012,JPO&INPIT |
