When a leaf spring,is rotated integrally with the rotation of a knob dial,, the leaf spring,is pushed and deflected by three corners of a cylindrical section,. After that, when three corners of the cylindrical section,get over the leaf spring,and new three surfaces are engaged with the leaf spring,, rotation of the knob dial,is regulated. In this case, the pushing direction of the leaf spring,is the same as the direction of deflection. Therefore, the rotational resistance of the knob dial,can be reduced. Accordingly, a feeling of operation of the knob dial,becomes light.
