<P>PROBLEM TO BE SOLVED: To provide a rotary operation member 50 which is provided to a rotation operation device comprising a panel 10, a circuit board 20 and a rotation detection element 30 provided on the circuit board 20, which can reliably move backward while keeping a correct posture when receiving over a constant pressing force even with a simple structure, and which can be easily designed. <P>SOLUTION: A rotation operation member 50 has an inner cylinder part 62 fitted with an operated shaft 34 of a rotation detection element 30, outside parts 63, 64 projecting from a panel surface side 15 and operated to rotate, and a restraining part 66 restraining the inner cylinder part 62 from moving backward. The restraining part 66 includes a projection part 68 connected to a tip end of the inner cylinder part 62, and projecting inward to contact a tip face 38 of the operated shaft 34. Furthermore, when a large pressing load is applied to the rotation operation member 50, the projection part 68 is detached from the tip face 38 of the operated shaft, and deformed to allow displacement of the inner cylinder part 62 along the operated shaft 34. <P>COPYRIGHT: (C)2012,JPO&INPIT |
