<p><P>PROBLEM TO BE SOLVED: To omit a space in the dropping direction for storing a member which adequately drops an operation knob when the size of the knob is increased and the load is applied from the outside in the dropping direction, and functions as a stopper. <P>SOLUTION: When the load equal to or more than a predetermined value is applied from the outside to an operation knob 1 in the dropping direction, stopper parts 11a, 11b provided on the inner circumferential side of a fitting cylindrical part 8 are bent, and an operation member 2 and a connection member 3 are integrally moved in the direction toward an encoder 4 side. In this condition, the stopper parts 11a, 11b bent in the axial direction from the radial direction are stored in storage parts 12a, 12b at which any movement of the fitting cylindrical part 8 in the axial direction along the outer circumference of a fitting part 14 is not impaired. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
