[0010] However, in the rotation operation type electronic component described in Patent Document 1, for example, in the case where the elastic portion disengages from the click engagement hole and in other cases, the operation torque varies, and thus it is not possible to obtain a stable and large operation torque for both the first rotation object and the second rotation object (both shafts).

[0030] The first block 10 is disposed on the axial direction side (+X direction). The first block 10 has a cylindrical portion 12. The cylindrical portion 12 has a first hole 14 that penetrates in the axial direction (X direction). The first hole 14 is demarcated by an inner peripheral surface 14a that connects an axial direction one side end surface 12a of the cylindrical portion 12 and an axial direction opposite side end surface 12b of the cylindrical portion 12.

[0032] The second hole 24 has a first space 241 disposed on the axial direction one side, a second space 242 disposed on the axial direction opposite side, and a third space 243 disposed on the axial direction central portion. The first space 241 is demarcated by a circular ring-shaped surface 241a facing the right side direction and an inner peripheral surface 241b connecting the surface 241a and an axial direction one side end surface 22a of the block portion 22. The second space 242 is demarcated by a surface 242a facing the left side direction and an inner peripheral surface 242b connecting the surface 242a and an axial direction opposite side end surface 22b of the block portion 22. The third space 243 is demarcated by an inner peripheral surface 243a connecting the surface 241a and the surface 242a.

[0033] ​​​The electronic signal control section 31 is disposed in the axial gap between the first block 10 and the second block 20. The electronic signal control section 31 corresponds to the "third block" of the present application.

[0034] The electronic signal control section 31 has a housing 311, a seat portion 312, and a terminal 313 that leads in and out an electric signal. The housing 311 has a rectangular parallelepiped shape. The housing 311 accommodates a variable resistor (not shown) that is rotationally driven by the outer operation shaft 40. An axial other side end surface 311a of the housing 311 abuts against an axial one side end surface 22a of the block portion 22. The seat portion 312 is disposed on the axial one side (right side) of the housing 311. The seat portion 312 has a seat surface 312a that abuts against an axial other side end surface 12b of the cylindrical portion 12.

[0035] The electronic signal control section 32 is disposed at a position farther on the axial other side than the second block 20. The electronic signal control section 32 has a housing 321 and a terminal 322 that leads in and out an electric signal. The housing 321 has a rectangular parallelepiped shape. The housing 321 accommodates a variable resistor (not shown) and a switch (not shown) that are rotationally driven by the inner operation shaft 50. An axial one side end surface 321a of the housing 321 abuts against an axial other side end surface 22b of the block portion 22.

[0036] The outer operation shaft 40 has a first cylindrical portion 41 and a first large diameter cylindrical portion 42. The first cylindrical portion 41 is fitted in the first hole 14 in a manner of rotating around the shaft. A radial gap S11 of a prescribed size is provided between the inner peripheral surface of the first hole 14 and the outer peripheral surface of the first cylindrical portion 41. The shape and size of the radial gap S11 are set by the inner diameter of the first hole 14 and the outer diameter of the first cylindrical portion 41. An axial other side end surface 41a of the first cylindrical portion 41 abuts against the seat surface 312a.

[0037] The first large diameter cylindrical portion 42 is disposed at a position farther on the axial one side (+X direction) than the first cylindrical portion 41, and has a larger diameter than the first cylindrical portion 41. An annular surface 43 that faces the left direction is disposed between the outer peripheral surface of the first cylindrical portion 41 and the outer peripheral surface of the first large diameter cylindrical portion 42. An axial gap S12 of a prescribed size is provided between the surface 43 and the axial one side end surface 12a.

[0038] The inner operation shaft 50 extends in the axial direction (X direction). The inner operation shaft 50 penetrates the first cylindrical portion 41, the inside of the seat portion 312, the inside of the housing 311, the second hole 24, and the inside of the housing 321. The inner operation shaft 50 has a small diameter portion 51, a large diameter portion 52, and a rotation stopping portion 53. The small diameter portion 51 is fitted in the first cylindrical portion 41 in a manner of rotating around the shaft. The large diameter portion 52 is disposed at a position farther on the axial one side (+X direction) than the small diameter portion 51, and has a larger diameter than the small diameter portion 51. An operation knob (not shown) is attached to the large diameter portion 52. The rotation stopping portion 53 is disposed at a position farther on the axial other side (-X direction) than the small diameter portion 51.

[0039] The axial other end portion 54 of the inner operation shaft 50 protrudes in the left direction (-X direction) from the axial other end surface 321b of the housing 321. A fall prevention ring 55 is attached to the axial other end portion 54 of the inner operation shaft 50.

[0040] The rotating body 60 has a second cylindrical portion 61 and a second large-diameter cylindrical portion 62. The second cylindrical portion 61 is fitted in the rotation-stopping portion 53 and is fitted in the third space 243. A radial gap S21 of a prescribed size is provided between the outer circumferential surface of the second cylindrical portion 61 and the inner circumferential surface of the third space 243. The shape and size of the radial gap S21 are set by the inner diameter of the third space 243 and the outer diameter of the second cylindrical portion 61. In the present embodiment, the shape and size of the radial gap S21 are set to be the same as the shape and size of the radial gap S11. The second large-diameter cylindrical portion 62 is fitted in the rotation-stopping portion 53 and is fitted in the first space 241. By the second cylindrical portion 61 and the second large-diameter cylindrical portion 62 being fitted in the rotation-stopping portion 53, the rotating body 60 rotates integrally with the inner operation shaft 50.

[0041] The second large-diameter cylindrical portion 62 is disposed at a position axially closer to the first space 241 than the second cylindrical portion 61, and has a larger diameter than the second cylindrical portion 61. The second large-diameter cylindrical portion 62 has a circular ring-shaped surface 62a facing in the left direction. An axial gap S22 of a prescribed size is provided between the surface 62a and the surface 241a.

[0042] Next, reference will be made to Figure 1 and Figure 2 An example of the first radial elastic member 70 will be described. Figure 2 is a perspective view showing an example of the first radial elastic member 70.

[0043] The first radial elastic member 70 is disposed in the radial gap S11 of a prescribed size. The first radial elastic member 70 is formed from a rectangular metal plate having a restoring force. On the metal plate, slits 70D are arranged parallel to each other at a prescribed interval in the long direction, the slits 70D being rectangular slits longer in the short direction of the metal plate. Thus, a plurality of spring plates 70A are formed, the ends of the plurality of spring plates 70A being connected to each other by two connecting bands 70B. The central region of each spring plate 70A in the length direction is formed so as to protrude in a bent shape to the same side with respect to the surface of the original metal plate. The spring plates 70A are wound so that the central region of each spring plate 70A in the length direction protrudes to the radial outside, and the two ends 70E, 70F of the metal plate are adjacent to each other, thereby obtaining a cylindrical spring. In the cylindrical spring, the connecting bands 70B function as fulcrums of the two ends of the spring plates 70A, and the central region of each spring plate 70A in the length direction functions as a fulcrum.

[0044] The first radial elastic member 70 is set so that its minimum inner diameter (inner diameter of the link band 70B) is smaller than the outer diameter of the first cylindrical portion 41 in a free state. Therefore, if the first radial elastic member 70 is attached to the first cylindrical portion 41, the interval 70C between the both ends 70E, 70F of the metal plate in the longitudinal direction expands against the restoring force, and the first radial elastic member 70 is held to the first cylindrical portion 41 by the restoring force. Also, the first radial elastic member 70 is set so that its maximum outer diameter (outer diameter of the central region of the spring plate 70A in the longitudinal direction) is larger than the diameter of the first hole 14 in this state.

[0045] If the outer side operation shaft 40 on which the first radial elastic member 70 is attached is inserted into the first hole 14, the spring plate 70A is pressed by the inner peripheral surface of the first hole 14 so that the height of the spring plate 70A in the radial direction is lowered to the inside in the radial direction. The outer side operation shaft 40 rotates together with the first radial elastic member 70, and the first radial elastic member 70 is rotationally slid with respect to the inner peripheral surface of the first hole 14. Thus, the outer side operation shaft 40 receives a frictional resistance from the inner peripheral surface of the first hole 14 via the first radial elastic member 70, and therefore, a torque required for the rotational operation can be obtained.

[0046] Next, the second radial elastic member 80 will be described with reference to Figure 1 and Figure 2 The second radial elastic member 80 is a general-purpose member used commonly with the first radial elastic member 70. The reason for using the general-purpose member is as described above, because the shape of the radial gap S21 is set to be the same size as the shape of the radial gap S11. Also, in the description of the second radial elastic member 80, the same reference numerals as those of the first radial elastic member 70 are used for the description.

[0047] The second radial elastic member 80 is disposed in the radial gap S21 having a prescribed size. The second radial elastic member 80 is set so that its minimum inner diameter (inner diameter of the link band 70B) is smaller than the outer diameter of the second cylindrical portion 61 in a free state. Therefore, if the second radial elastic member 80 is attached to the second cylindrical portion 61, the interval 70C between the both ends 70E, 70F of the metal plate in the longitudinal direction expands against the restoring force, and the second radial elastic member 80 is held to the second cylindrical portion 61 by the restoring force. Also, the second radial elastic member 80 is set so that its maximum outer diameter (outer diameter of the central region of the spring plate 70A in the longitudinal direction) is larger than the diameter of the second hole 24 in this state.

[0048] The rotating body 60 is fitted to the rotation-preventing portion 53 of the inner operating shaft 50, and thus rotates integrally with the inner operating shaft 50. As described above, the second radial elastic member 80 is attached to the second cylindrical portion 61 of the rotating body 60. When the rotating body 60 to which the second radial elastic member 80 is attached is inserted into the second hole 24, the spring plate 70A is pressed by the inner circumferential surface of the second hole 24, and the height of the spring plate 70A in the radial direction is lowered toward the inner side in the radial direction. The inner operating shaft 50 that rotates integrally with the rotating body 60 rotates together with the second radial elastic member 80, and the second radial elastic member 80 rotates in sliding contact with the inner circumferential surface of the second hole 24. Thus, the inner operating shaft 50 (the rotating body 60) receives a frictional resistance from the inner circumferential surface of the second hole 24 via the second radial elastic member 80, and thus a torque required for the rotational operation can be obtained.

[0049] Next, the operation of the second radial elastic member 80 will be described with reference to FIG. 6. Figure 1 The first axial elastic member 91 is a spring washer, for example, which is sandwiched in the axial gap S12 in a state of being bent against a restoring force. The outer operating shaft 40 rotates in sliding contact with the first axial elastic member 91. Thus, the outer operating shaft 40 receives a frictional resistance from the first axial elastic member 91, and thus a torque required for the rotational operation can be obtained.

[0050] Next, the operation of the second axial elastic member 92 will be described with reference to FIG. 7. Figure 1 The second axial elastic member 92 is a general-purpose member that is used commonly with the first axial elastic member 91. The reason for using the general-purpose member is that the size of the axial gap S21 is set to be the same as the size of the axial gap S22. The second axial elastic member 92 is sandwiched in the axial gap S22 in a state of being bent against a restoring force. The rotating body 60 that rotates integrally with the inner operating shaft 50 rotates in sliding contact with the second axial elastic member 92. Thus, the inner operating shaft 50 (the rotating body 60) receives a frictional resistance from the second axial elastic member 92, and thus a torque required for the rotational operation can be obtained. Furthermore, in order to improve the operability, it is preferable that the operation torque of the inner operating shaft 50 and the operation torque of the outer operating shaft 40 be within a prescribed range.

[0051] However, a deviation occurs in the axial gap S22 due to dimensional tolerances of the components and the like. In the case where the axial gap S22 is large, the frictional resistance from the second axial elastic member 92 decreases, and the operation torque of the inner operating shaft 50 decreases. In the case where the axial gap S22 is small, the frictional resistance from the second axial elastic member 92 increases, and the operation torque of the inner operating shaft 50 increases. Due to the deviation of the axial gap S22, the operation torque of the inner operating shaft 50 sometimes deviates from the prescribed range.

[0052] The operation torque of the inner operation shaft 50 is adjusted by disposing the torque adjustment member 100 in the axial gap between the axial one side end surface 62b of the second large diameter cylindrical portion 62 and the axial other side end surface 311a of the housing 311. The torque adjustment member 100 is, for example, a washer. The operation torque of the inner operation shaft 50 is adjusted by selectively using a washer suitable for the axial gap from among a plurality of washers that differ in plate thickness.

[0053] The rotation operation type electronic component 1 of the above embodiment includes: a first block 10 disposed on an axial one side and having a first hole 14; a second block 20 disposed on an axial other side and having a second hole 24; an outer operation shaft 40 having a first cylindrical portion 41 that is inserted into the first hole 14 in a manner of rotating around an axis; an inner operation shaft 50 extending in an axial direction, penetrating the first cylindrical portion 41 and the second hole 24, and being inserted into the first cylindrical portion 41 in a manner of rotating around an axis; a rotation body 60 having a second cylindrical portion 61 that is inserted into the inner operation shaft 50 in a manner of rotating integrally with the inner operation shaft 50 and is inserted into the second hole 24 in a manner of rotating around an axis; a first radial elastic member 70 that is sandwiched in a radial gap S11 between an inner peripheral surface of the first hole 14 and an outer peripheral surface of the first cylindrical portion 41 in a state of being bent against a restoring force; and a second radial elastic member 80 that is sandwiched in a radial gap S21 between an inner peripheral surface of the second hole 24 and an outer peripheral surface of the second cylindrical portion 61 in a state of being bent against a restoring force.

[0054] With the above structure, the outer operation shaft 40 receives a frictional resistance from the inner peripheral surface of the first hole 14 via the first radial elastic member 70 in a case where the outer operation shaft 40 is rotationally operated, and thus a torque required for the rotation operation can be obtained. Also, the inner operation shaft 50 receives a frictional resistance from the inner peripheral surface of the second hole 24 via the second radial elastic member 80 in a case where the inner operation shaft 50 is rotationally operated, and thus a torque required for the rotation operation can be obtained. Thus, both of the shafts (the outer operation shaft 40 and the inner operation shaft 50) can obtain a stable and large operation torque.

[0055] Also, the rotation operation type electronic component 1 of the above embodiment includes: a first axial elastic member 91 that is sandwiched in an axial gap S12 in a state of being bent against a restoring force; and a second axial elastic member 92 that is sandwiched in an axial gap S22 in a state of being bent against a restoring force. Thus, both of the shafts can obtain a higher operation torque.

[0056] Also, the rotation operation type electronic component 1 of the above embodiment includes a washer (torque adjustment member) that is disposed in an axial gap between the second large diameter cylindrical portion 62 and the housing 311 and adjusts an operation torque of the inner operation shaft. Thus, the operation torque of the inner operation shaft 50 can be adjusted by selectively using a washer suitable for the above axial gap from among a plurality of washers that differ in plate thickness.

[0057] Next, referring to Figure 3A and Figure 3B , each modification of the rotation operation type electronic component 1 of the above embodiment will be described. In the description of the modifications, the structure different from the above embodiment will be mainly described, and the same reference numerals will be given to the same structure and the description thereof will be omitted. Further, in the description of the modifications, the same reference numerals will be given to the same structure as that of the above embodiment and the description thereof will be omitted. Figure 3A In Modification 1 shown in FIG. 17 and Figure 3B Modification 2 shown in FIG. 18, the axial gap S22 is emphasized and depicted.

[0058] In Modification 2, the operation torque of the inner operation shaft 50 is adjusted without using a washer (torque adjustment member).

[0059] The reason why the axial gap S22 is made larger as shown in Figure 3A , for example, is that in a case where the operation torque of the inner operation shaft 50 is larger than the operation torque of the outer operation shaft 40 and exceeds a prescribed range, a rotation body 60 having a thinner plate thickness of the second large diameter cylindrical portion 62 is selected, the axial gap S22 is made larger than a reference dimension, and the operation torque of the inner operation shaft 50 is decreased to converge within the prescribed range.

[0060] The reason why the axial gap S22 is made smaller as shown in Figure 3B , for example, is that in a case where the operation torque of the inner operation shaft 50 is smaller than the operation torque of the outer operation shaft 40 and does not reach a prescribed range, a rotation body 60 having a thicker plate thickness of the second large diameter cylindrical portion 62 is selected, the axial gap S22 is made smaller than a reference dimension, and the operation torque of the inner operation shaft 50 is increased to converge within the prescribed range.

[0061] According to each of the above modifications, for example, the operation torque of the inner operation shaft 50 can be adjusted by selectively using a suitable rotation body 60 from among a plurality of rotation bodies 60 different in plate thickness of the second large diameter cylindrical portion 62.

[0062] Further, the above embodiment merely shows one example of the embodiment of the present application, and the technical scope of the present application is not limitedly interpreted thereby. That is, the present application can be embodied in various ways without departing from the gist or main features thereof.

[0063] In the above-described embodiment, the rotation operation type electronic component 1 is provided with both the first axial elastic member 91 and the second axial elastic member 92, but the present application is not limited to this, and for example, it can be provided with only one of the first axial elastic member 91 and the second axial elastic member 92, or it can be provided with neither of the first axial elastic member 91 and the second axial elastic member 92 for the reason that sufficient operation torque and the like can be obtained with the first radial elastic member 70 and the second radial elastic member 80.

[0064] The present application is based on Japanese Patent Application (JP 2020-010788) filed on January 27, 2020, the contents of which are incorporated by reference.
