An operation knob apparatus includes a base a conductive transmitting member, an operation member that brings the transmitting member near to and away from a display panel, and a stabilizer disposed between the bases and the operation member. The stabilizer includes a main body, a pair of arms connected to respective ends of the main body, and a pair of base portions and connected to the respective arms. One of the base and the operation member has a holding portion configured to rotatably hold the main body, and the other has a pair of holding grooves respectively configured to slidably and rotatably hold the base portions.

Operation knob apparatus

An operation knob device includes an annular holder having an annular holding portion, an annular rotor arranged in the holding portion so as to allow rotation around an axis, an annular knob for which relative movement in a direction along the axis with respect to the rotor is allowed and relative movement in a circumferential direction around the axis is restricted, a first transmission member arranged on a side of a first end of the rotor so as to move with the knob, and a second transmission member attached to the first end so as to rotate integrally with the rotor. The knob has cylindrical inner and outer wall portions, and an opening through which part of a display panel can be visually recognized is defined by the inner wall portion. The first and second transmission members are arranged between the inner wall portion and the outer wall portion.

Operation knob device

An operation knob device includes a holder arranged adjacent to a display panel, a rotor arranged in a holding portion so as to allow rotation around an axis, a knob for which relative movement in a direction along the axis with respect to the rotor is allowed and relative movement in a circumferential direction around the axis is restricted, a conductive transmission member arranged on a first end side of the rotor. The transmission member includes a first transmission member that moves along the axis in conjunction with the knob, a second transmission member that is attached to the first end so as to rotate integrally with the rotor, and a connecting member that conductively connects the first transmission member and the second transmission member.
