The sliding member 80 is fixed to the rotating body 50 by inserting it into 87 and caulking the tip thereof. On the other hand, the click plate 100 is disposed on the lower surface of the upper surface plate 131 of the cover 130, and at that time, the pair of attachment portions 139 of the cover 130 are inserted into the pair of cover attachment portions 103 of the click plate 100. The click plate 100 is attached to the lower surface of the upper surface plate 131 of the cover 130 by crimping.

  The grease 150 is attached to the outer peripheral portion (the portion that is supported by the shaft support portion 135 of the cover 130) (the portion A indicated by the dotted line in FIGS. 3 and 4) of the lower portion of the shaft portion 53 of the rotating body 50 to which the slider 80 is attached. , The rotating body main body 51 of the rotating body 50 is housed in the rotating body housing recess 13 of the case 10, and the vicinity of the outer periphery of the lower surface of the rotating body main body 51 is the rotating body mounting portion 25 of the case 10. Abuts and rests on the top surface. As the grease 150, mineral oil-based grease is used (other grease may be used).

  Next, the cover 130 is put on the case 10, and the shaft portion 53 of the rotating body 50 is inserted into the shaft support portion 135 of the cover 130 at that time. The upper surface plate 131 of the cover 130 is brought into contact with the upper surface of the case 10, and at this time, both end portions of the click plate 100 are accommodated in the click plate insertion portion 19 of the case 10, and the locking portion 17 of the case 10 is inserted into the cover 130. It is inserted into the locking portion 137 and positioned. At this time, both side plates 133 and 133 of the cover 130 abut against the opposing outer peripheral side surfaces of the case 10 exactly. And if the front-end | tip part of each case attaching part 143 of the cover 130 is bend | folded to the lower surface of the case 10 and the cover 130 and the case 10 are integrated, the rotary electronic component 1-1 will be completed.

  As described above, when the shaft portion 53 of the rotating body 50 is inserted into the shaft support portion 135 of the cover 130 from the lower surface side of the cover 130, a part of the grease 150 applied to the shaft portion 53 (the shaft portion 53 and the shaft support portion). The surplus grease other than the grease adhering between 135) is moved to the rotating body main body 51 side, reaches the upper surface of the bearing portion 55, and is smoothly introduced into the grease introduction recess 63. The grease 150 introduced into the grease introduction recess 63 is smoothly introduced into the click engagement recess 61 communicating with the grease introduction recess 63.

  That is, since the grease introduction recess 63 is provided on the upper surface of the rotating body main body 51, when the rotating electronic component 1-1 is assembled, it is applied between the shaft support portion 135 of the cover 130 and the shaft portion 53 of the rotating body 50. The grease 150 is guided to the click engagement recess 61 through the grease introduction recess 63. That is, the grease 150 is supplied to the two portions by a simple operation of applying the grease 150 to one place, thereby facilitating the assembling work of the rotary electronic component 1-1. In particular, according to the rotary electronic component 1-1, since the grease introducing recess 63 is provided in the portion of the bearing portion 55 originally formed in the rotating body main body 51, the structure of the rotating body 50 is not complicated. The grease introduction recess 63 can be easily formed.

  FIG. 7 is a perspective view showing a state in which the cover 130 is removed from the rotary electronic component 1-1. Since the click plate 100 is actually fixed to the cover 130, the state shown in FIG. The state shown in the figure shows a state where the elastic contact portion 101 of the click plate 100 is engaged with the click engagement recess 61 of the rotating body 50.

  When the rotating body 50 is rotated, the slider 80 slides on the sliding contact pattern 31 of the flexible circuit board 30, and the electrical output between the terminal boards 45 changes.

  On the other hand, when the rotary body 50 is rotated, the elastic contact portion 101 of the click plate 100 slides while elastically contacting the click elastic contact surface 57 of the rotary body 50, and a predetermined rotational position of the rotary body 50 (position shown in FIG. 7). In this way, the click engagement recess 61 is engaged to generate a click feeling. As described above, the grease 150 is introduced and accumulated in the click engagement recess 61, and the grease 150 adheres to the elastic contact portion 101. For this reason, even if a strong elastic contact force acts between the elastic contact portion 101 and the click elastic contact surface 57, the synthetic resin and the metal are not directly rubbed by the oil film of the grease 150 (the friction coefficient is small and the friction force is also small). Static electricity is unlikely to occur. For this reason, electrostatic noise does not enter the electrical output of the rotary electronic component 1-1.

  The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures. For example, in the above assembly example, after the rotating body main body 51 of the rotating body 50 coated with the grease 150 is stored in the rotating body storage recess 13 of the case 10, the cover 130 is put on the case 10. The shaft portion 53 of the rotating body 50 coated with the grease 150 may be inserted into the shaft support portion 135 from the lower side, and the cover 130 to which the rotating body 50 is attached may be put on the case 10. Also, the timing of applying the grease 150 can be changed, and the timing may be any time before the shaft portion 53 of the rotating body 50 is inserted into the shaft support portion 135 of the cover 130.

  As described above, the rotary electronic component 1-1 includes the case 10, the rotating body having the rotating body main body 51 housed in the case 10, and the shaft portion 53 protruding from the upper surface of the rotating body main body 51. 50, a cover 130 that has a shaft support portion 135 that supports the outer peripheral surface of the shaft portion 53 through the shaft portion 53 of the rotating body 50 and covers the upper portion of the case 10 that houses the rotating body main body portion 51, and the rotating body main body A click plate 100 having a resilient contact portion 101 that engages and disengages from a click engagement recess 61 provided on the upper surface of the portion 51, and a shaft portion 53 that protrudes from the shaft portion 53 on the upper surface of the rotating body main body 51 has a shaft The grease 150 applied between the support portion 135 and the shaft portion 53 is provided with a grease introduction recess 63 that leads to the click engagement recess 61.

  Further, in the rotary electronic component 1-1, a bearing portion 55 that abuts the cover 130 is provided at a root portion 71 that projects the shaft portion 53 on the upper surface of the rotating body main body 51. The grease introduction recess 63 is provided.

That is, the grease 150-2 is supplied to the two portions by a simple operation of applying the grease 150-2 in one place, thereby facilitating the assembling work of the rotary electronic component 1-2. In particular, according to the rotary electronic component 1-2, since the grease introduction recess 63-2 is provided in the portion of the bearing portion 55-2 originally formed in the rotary body main body 51-2, the rotary body 50-2 is provided. The grease introduction recess 63-2 can be easily formed without complicating the structure.

  FIG. 11 is an exploded perspective view showing a rotary electronic component 1-3 according to the third embodiment of the present invention. In the rotary electronic component 1-3 shown in the figure, the same or corresponding parts as those of the rotary electronic component 1-1 shown in FIGS. 1 to 7 are denoted by the same reference numerals (provided that “-3” is added to each reference numeral). To do.) Note that matters other than those described below are the same as those in the embodiment shown in FIGS. Also in the rotary electronic component 1-3, the rotary body main body 51-3 of the rotary body 50-3 to which the slider 80-3 is attached is stored in the rotary body storage recess 13-3 of the case 10-3. In addition, a click plate 100-3 is installed thereon, and a cover 130-3 is further placed thereon.

  The only difference between the rotary electronic component 1-3 and the rotary electronic component 1-1 is the structure of the rotating body 50-3. That is, in the rotating body 50-3 according to this embodiment, not only the grease introduction recess 63-3 is provided in the bearing portion 55-3 but also the grease introduction recess 63-3 provided in the bearing portion 55-3. It is provided so that it may be located also in the part of the axial part outer peripheral surface 73-3 of the axial part 53-3.
