As shown in FIG. 3 (a), a magnet group 5 as an attracting member is fitted in an annular shape on the inner periphery of the hole portion 2 of the operation knob 1, and the outer periphery of the shaft portion 4 of the mounting member 3. A magnet group 6 as an adsorbent is fitted in an annular shape. The operation knob 1 is supported by the mounting member 3 so as to be rotatable about a center line 4 a of the shaft portion 4, and the inner periphery of the magnet group 5 centering on the rotation center line 4 a of the operation knob 1 with respect to the mounting member 3. The surface and the outer peripheral surface of the magnet group 6 are opposed to each other with a slight gap therebetween or in contact with each other. As shown in FIG. 1B, a pointer 7 is attached to the flange 1 a formed on the outer periphery of the operation knob 1, and a plurality of scales 8 are provided on the mounting member 3 along the flange 1 a of the operation knob 1.

One adsorbent and the other adsorbent of the attachment member-side adsorbent and the operation knob-side adsorbent respectively move the N pole of the magnet and the S pole of the magnet in the relative movement direction of the operation knob. The magnet groups are arranged to generate an attractive magnetic force between the N pole of the magnet of one magnet group and the S pole of the magnet of the other magnet group at the moving operation position of the operation knob, and An attractive magnetic force is generated between the S pole and the N pole of the magnet of the other magnet group, and the operating knob has a moving operation force when the operating knob is moved relative to the mounting member from the moving operating position of the operating knob. So that a repulsive magnetic force is generated between the N pole of the magnet of one magnet group and the N pole of the magnet of the other magnet group, and the S pole of the magnet of one magnet group and the S pole of the magnet of the other magnet group. The operation dial according to claim 1, wherein a repulsive magnetic force is generated between Rick mechanism. Of the attachment member-side adsorption body and the operation knob-side adsorption body, one of the adsorption bodies is a magnet, and the other adsorption body is magnetically attracted by the magnet's attractive magnetic force at the operation knob moving operation position. The click mechanism for an operation dial according to claim 1, wherein the click mechanism is a body. Of the attachment member side adsorption body and the operation knob side adsorption body, one adsorption body is a magnet group in which the N pole of the magnet and the S pole of the magnet are arranged in the relative movement direction of the operation knob. In the adsorbent, the teeth of the magnetic body attracted by the magnetic attraction force of the magnet N-pole and magnet S-pole in this magnet group are arranged in the relative movement direction of the operation knob with a gap between them. The attractive magnetic force generated when the N-pole of the magnet and the S-pole of the magnet in this magnet group are opposed to the teeth of the magnetic body causes the N-pole and S-pole of the magnet in this magnet group to be magnetized. 2. The click mechanism in the operation dial according to claim 1, wherein the click mechanism is larger than an attractive magnetic force generated when facing a gap in the body.
