A signal is output in response to the pressing operation. Further, a spacer 15 is provided so as to face the insulating case 14.

  After incorporating the above-described components, each of the legs 2b of the mounting plate 2 shown in FIG. 1 and the like is bent toward the back side of the spacer 15 to form a single product, that is, a rotary encoder.

  In the embodiment configured as described above, in the assembled state as shown in FIGS. 2 and 3, the bearing 4 is fixed by the mounting plate 2, and the leaf spring 5 is attached to the bearing 4. 8 is held so as to be movable in the axial direction of the rotary shaft 1 with respect to the bearing 4, and the insulating cases 11 and 14 and the spacer 15 are fixed by the mounting plate 2 with the metal contacts 12 and 13 interposed therebetween.

  The spacer 6 and the click member 8 are accommodated in the large diameter hole 4b of the large diameter portion 4a of the bearing 4 together with the coil spring 7 in a state where the coil spring 7 is compressed. As a result, the click member 8 is urged toward the rotating member 9 by the coil spring 7.

  The non-circular portion 1c forming the shaft portion of the rotating shaft 1 is inserted into the non-circular hole 9e of the boss portion 9d of the rotating member 9, and further the non-circular hole of the driving body 10 that rotates integrally with the rotating member 9. 10c is also inserted. Further, the pair of pressing portions 5 c of the leaf spring 5 presses the outer peripheral portion 9 h of the plate-like portion 9 c of the rotating member 9.

  Then, the common pattern portion 9m of the rotating member 9 and the pair of first sliders 11b of the insulating case 11 come into contact with each other, and the code pattern portion 9n of the rotating member 9 and the second slider 11c of the insulating case 11 and the third slider 11b. The state in which the slider 11d is in selective contact is maintained.

  The driving body 10 is inserted into the hole 11 a of the insulating case 11, and the hemispherical projection 10 b of the driving body 10 is held in contact with the top of the metal contact 12.

  In such a state, when the knob 1a of the rotating shaft 1 is rotated, the rotational force causes the non-circular hole 9e formed in the boss portion 9d of the rotating member 9 to engage with the non-circular portion 1c of the rotating shaft 1. Via the boss portion 9d of the rotating member 9. Further, the rotational force applied to the rotating shaft 1 rotates through the engagement between the non-circular portion 1c of the rotating shaft 1 and the non-circular hole 10c formed in the driving body 10 and the convex portion 10a of the driving body 10. This is transmitted to the plate-like portion 9 c of the member 9. As a result, the rotating member 9 rotates smoothly.

  During this time, each of the plurality of uneven portions 9f of the rotating member 9 is engaged with and disengaged from each of the plurality of uneven portions 8b of the click member 8, and a good click feeling is obtained. In the click operation, the click member 8 moves in the axial direction of the rotary shaft 1 against the elastic force of the coil spring 7 through the movement of the convex portion 8 a of the click member 8 in the concave portion 4 c of the bearing 4.

  Further, when the pair of pressing portions 5 c of the leaf spring 5 presses the outer peripheral portion 9 h of the rotating member 9, rotational torque is obtained. That is, when the rotary shaft 1 is rotated, a relatively large resistance feeling due to the elastic force of the leaf spring 5 can be felt.

  Further, the pair of first sliders 11b of the insulating case 11 is always in conduction with the common pattern portion 9m of the rotating member 9, and the second slider 11c of the insulating case 11 is connected to the code pattern portion 9n of the rotating member 9 with. By selectively conducting with the third slider 11d, the rotation angle and the rotation direction of the rotating shaft 1 can be detected.

It contacts the central fixed contact 14 i of the insulating case 14. As a result, the peripheral fixed contact 14 h and the central fixed contact 14 i are brought into conduction through the metal contacts 12 and 13, and an ON signal can be output from the insulating case 14. The drive body 10 is made of an elastomer, and thereby, undesired sound is generated as compared with the case where the metal contacts 12 and 13 are pressed by a shaft portion such as the non-circular portion 1c of the rotating shaft 1 made of metal. Can be reduced.

  According to the present embodiment configured as described above, the leaf spring 5 for applying a load to the rotating member 9, that is, the leaf spring 5 for generating the rotational torque is arranged on the outer peripheral side of the click member 8. The shape dimension is not restricted by the click member 8. Therefore, the shape and size of the leaf spring 5 can be increased, the elastic force of the leaf spring 5 can be set large, and the pressing position 5c of the rotating member 9 against the plate-like portion 9c by the pressing portion 5c of the leaf spring 5 ( The distance between the portion 9c1) and the axis of the rotary shaft 1 can be increased. Thereby, rotational torque can be made heavy.

  Further, since both the leaf spring 5 and the click member 8 may be incorporated on the front side of the rotating member 9, they can be easily assembled. As a result, excellent incorporation is obtained.

  Further, since the leaf spring 5 is brought into contact with the outer peripheral portion 9h of the plate-like portion 9c of the rotating member 9 at a position facing the axis of the rotating shaft 1, a large load caused by the leaf spring 5 is rotated at two locations. It can be added to the member 9. This contributes to increasing the rotational torque.

  Further, the thickness dimension of the portion 9c1 of the rotating member 9 with which the pressing portion 5c of the leaf spring 5 abuts is determined from the thickness dimension of the portion 9c2 of the uneven portion 9f of the rotating member 9 with which the uneven portion 8b of the click member 8 is engaged and disengaged. Therefore, the strength of the portion 9c1 of the rotating member 9 with which the leaf spring 5 abuts can be ensured. Thereby, deformation of the rotating member 9 due to urging of the leaf spring 5 can be prevented.

  In addition, the click member 8 includes a plurality of uneven portions 8 b that engage with and disengage from the plurality of uneven portions 9 f of the rotating member 9, and the coil member 7 that biases the click member 8 toward the rotating member 9. As the rotary shaft 1 rotates, each of the plurality of uneven portions 8b of the click member 8 and each of the plurality of uneven portions 9f of the rotating member 9 can be engaged and disengaged simultaneously. Thereby, a favorable click feeling is obtained over a long period of time.

  Further, at least the concave portion 9f1 of the concave-convex portion 9f of the rotating member 9 is depressed so as to form a step 9g between the outer peripheral portion 9h, and the concave-convex portion 9f of the rotating member 9 and the concave-convex portion 8b of the click member 8 are formed. Since the grease is provided between them, the wear of the uneven portion 9f of the rotating member 9 and the uneven portion 8b of the click member 8 accompanying the rotation of the rotating shaft 1 can be suppressed by the grease. As a result, a good click feeling over a long period can be maintained. Further, by interposing the grease, it is possible to reduce the generation of abnormal noise when a click feeling is generated.

  In the above embodiment, the metal plate for forming the conductive portion 9i is insert-molded on the plate-like portion 9c of the rotating member 9 made of synthetic resin. However, the present invention is not limited to this configuration. I can't. An insulating substrate on which a pattern is printed may be attached to the rotating member 9.
