Slide switch 20C is a selector switch for selecting the focus position, and push button switch 22 is a confirmation switch for setting the focus position to a predetermined position.

[0039] Each slide switch 20 has a slidable operation unit 24. The operation direction of each slide switch 20 (i.e., the direction in which the operation unit 24 moves) is set to the direction of arrow X. The push button switch 22 has a pressable operation unit 26. The operation direction of the push button switch 22 (i.e., the direction in which the operation unit 26 moves) is set to the radial direction of the fixed frame 16.

[0040] The switch unit 18 has a plurality of slide switches 20 and a push button switch 22, but any one of the plurality of slide switches 20 and the push button switch 22 may be omitted. The switch unit 18 may also have switches other than those described above as an example of a plurality of switches. The switch unit 18 may also have switches related to operations other than those of the lens. Examples of switches related to operations other than those of the lens include a power switch.

[0041] Next, the configuration of the switch unit 18 will be described. As shown in FIGS. 3 and 4, the switch unit 18 is configured as a unit before being attached to the fixed frame 16 (see FIGS. 1 and 2), and includes an outer case 28 and an inner case 30 in addition to a plurality of slide switches 20 and push button switches 22. The outer case 28 is an example of an "outer member" according to the technology of the present disclosure, and the inner case 30 is an example of an "inner member" according to the technology of the present disclosure. The outer case 28 and the inner case 30 are formed in an arc shape. The outer case 28 forms the outer periphery of the switch unit 18, and the inner case 30 forms the inner periphery of the switch unit 18.

[0042] More specifically, the outer case 28 has an exterior portion 32 and a case portion 34. The exterior portion 32 is formed in the shape of an arc-shaped plate, and the case portion 34 is provided on the inner periphery of the exterior portion 32.

[0043] The inner case 30 is attached to the case portion 34 from the inner circumferential side of the switch unit 18. The inner case 30 and the case portion 34 form a storage portion 36 that stores the components (see FIG. 5) that make up the switch unit 18, which will be described later. The exterior portion 32 is formed in an elongated shape with the direction of arrow X as its short side direction and the direction around the optical axis as its long side direction. The exterior portion 32 is formed larger than the storage portion 36 and has a flange portion 38 that protrudes from the periphery of the storage portion 36. More specifically, the flange portion 38 has a pair of first flange portions 38A extending in the long side direction of the exterior portion 32 and a pair of second flange portions 38B extending in the short side direction of the exterior portion 32.

[0044] As shown in FIG. 5, the switch unit 18 has an outer case 28, an inner case 30, a plurality of first screws 40, a sealing member 42, a flexible cable 44, a plurality of switch members 46, a switch member 48, a plurality of second screws 50, an attachment member 52, a plurality of click members 54, a holding member 56, a plurality of double-sided tapes 58, a plurality of operating units 24, and an operating unit 26.

[0045] The plurality of first screws 40 are used to fasten the case portion 34 of the outer case 28 to the inner case 30. The seal member 42 is sandwiched between the case portion 34 of the outer case 28 and the inner case 30, and seals the gap between the case portion 34 and the inner case 30. The flexible cable 44 has a plurality of input portions 60 and an output portion 62. The plurality of input portions 60 and the output portion 62 are connected by wiring members (not shown). The output portion 62 is connected to, for example, a control board (not shown) provided in the lens device 10. Each switch member 46 constitutes a switch body of each slide switch 20, and the switch member 48 constitutes a switch body of the push button switch 22. Each switch member 46 and switch member 48 are connected to each input portion 60.

[0046] Each click member 54 is a member for imparting a clicking sensation to the operating portion 24 of each slide switch 20, and is formed from a sheet metal plate. Each second screw 50 is a screw for fixing each click member 54 to the outer case 28. A plurality of openings 64 and an opening 66 are formed in the outer case 28. Each opening 64 penetrates the outer case 28 in the thickness direction and opens to both the outer periphery and the inner periphery of the outer case 28. Similarly, opening 66 also penetrates the outer case 28 in the thickness direction and opens to both the outer periphery and the inner periphery of the outer case 28.

[0047] The operating portion 24 of each slide switch 20 is provided on the outer periphery of the outer case 28, and is fixed to the click member 54 with double-sided tape 58 through openings 64. Each click member 54 is attached to the switch member 46 of each slide switch 20. The holding member 56 is fixed to the switch member 48 of the push button switch 22 through an attachment member 52. The operating portion 26 of the push button switch 22 is held by the holding member 56, and is exposed to the outer periphery of the outer case 28 through openings 66.

[0048] Next, a fixing structure for fixing the switch unit 18 to the fixed frame 16 will be described. As described above, the direction of arrow X indicates the direction along the optical axis OA. The direction of arrow Y indicates the mounting direction of the switch unit 18 to the fixed frame 16. The side of arrow Y1 indicates the front side in the mounting direction, and the side of arrow Y2 indicates the rear side in the mounting direction. The direction of arrow Z indicates the direction along the tangential direction of the fixed frame 16. The side of arrow Z1 indicates the first side in the tangential direction of the fixed frame 16, and the side of arrow Z2 indicates the second side in the tangential direction of the fixed frame 16. The directions of arrow X, arrow Y, and arrow Z are perpendicular to each other.

[0049] 6 to 8, the fixed frame 16 has an opening 68. The opening 68 is formed by a hole penetrating in the direction of arrow Y. The opening 68 is formed in a rectangular shape corresponding to the outer shape of the inner case 30. The direction of arrow Y corresponds to the direction along the radial direction of the fixed frame 16. The opening 68 may also be formed by a notch penetrating the fixed frame 16 in the radial direction.

[0050] The outer shape of the outer case 28 is larger than the opening 68, and the outer shape of the inner case 30 is smaller than the opening 68. The outer shape of the outer case 28 is formed by the outer periphery of the flange portion 38. The outer shape of the inner case 30 is formed by the outer periphery of the inner case 30. The outer shape of the case portion 34 is also smaller than the opening 68. The outer shape of the case portion 34 is formed by the outer periphery of the case portion 34. Since the outer shapes of the inner case 30 and the case portion 34 are smaller than the opening 68, they are configured to be insertable into the opening 68 from outside the fixed frame 16. The switch unit 18 is unitized at a stage before the inner case 30 and the case portion 34 (i.e., the storage portion 36) are inserted into the opening 68.

[0051] The switch unit 18 is assembled to the fixed frame 16 by inserting the inner case 30 and the case portion 34 into the opening 68. When the switch unit 18 is assembled to the fixed frame 16, the flange portion 38 of the outer case 28 is overlapped with the peripheral edge of the opening 68 from the outside of the fixed frame 16. The flange portion 38 is an example of an "overlapping portion" according to the technology of the present disclosure. Furthermore, when the switch unit 18 is assembled to the fixed frame 16, the outer case 28 is disposed facing the outside of the fixed frame 16, and the inner case 30 is disposed facing the inside of the fixed frame 16. In other words, the outer case 28 is exposed to the outside of the fixed frame 16, and the inner case 30 is exposed to the inside of the fixed frame 16.

[0052] The lens device 10 has a pair of fixing members 70. When the switch unit 18 is assembled to the fixed frame 16, it is fixed to the fixed frame 16 by the pair of fixing members 70. Specifically, each fixing member 70 has a fixed portion 72 and a mating portion 74. The inner case 30 of the switch unit 18 has a pair of fixing portions 76, and the inner circumferential surface of the fixed frame 16 has a pair of mating portions 78. When the inner case 30 and the case portion 34 are inserted into the opening 68 and the switch unit 18 is assembled to the fixed frame 16, the fixed portions 72 of each fixing member 70 are fixed to the respective fixing portions 76, and the mating portions 74 of each fixing member 70 are mated with the respective mating portions 78, thereby fixing the switch unit 18 to the fixed frame 16.

[0053] One of the pair of fixing portions 76 is provided at a first end of the inner case 30, and the other of the pair of fixing portions 76 is provided at a second end opposite the first end of the inner case 30. The first end of the inner case 30 is an end located on one side of the inner case 30 in the circumferential direction of the fixed frame 16, and the second end of the inner case 30 is an end located on the other side of the inner case 30 in the circumferential direction of the fixed frame 16. The first end is an example of a "first end of the switch portion" according to the technology of the present disclosure, and the second end is an example of a "second end of the switch portion" according to the technology of the present disclosure.

[0054] One of the pair of fixing members 70 is fixed to one fixing portion 76 and is thereby arranged at a first end of the inner case 30, and the other of the pair of fixing members 70 is fixed to the other fixing portion 76 and is thereby arranged at a second end of the inner case 30. With one fixing member 70 arranged at the first end of the inner case 30 and the other fixing member 70 arranged at the second end of the inner case 30, the pair of fixing members 70 are arranged spaced apart in the circumferential direction of the fixing frame 16. In other words, the pair of fixing members 70 are arranged spaced apart in the direction of arrow Z, which indicates the tangential direction of the fixing frame 16. One of the pair of fitting portions 78 is formed at a position corresponding to one of the fixing portions 76, and the other of the pair of fitting portions 78 is formed at a position corresponding to the other fixing portion 76.

[0055] Although a pair of fixing members 70 are used to fix the switch unit 18 to the fixing frame 16, three or more fixing members 70 may be used. Any number of fixing members 70 may be used. Below, an example will be described in which a pair of fixing members 70 is used. The pair of fixing members 70 is an example of "multiple fixing members" according to the technology of the present disclosure. One of the fixing members 70 is an example of a "first fixing member" according to the technology of the present disclosure. The other fixing member 70 is an example of a "second fixing member" according to the technology of the present disclosure.

[0056] The fixing structure of one fixing member 70 to the switch unit 18 and the fixing structure of the other fixing member 70 to the switch unit 18 are configured symmetrically in the direction of the arrow Z. Similarly, the fitting structure of one fixing member 70 to the fixing frame 16 and the fitting structure of the other fixing member 70 to the fixing frame 16 are configured symmetrically in the direction of the arrow Z. Below, the fixing structure located on the arrow Z1 side of the pair of fixing structures will be described, and a description of the fixing structure located on the arrow Z2 side of the pair of fixing structures will be omitted. Similarly, the fitting structure located on the arrow Z1 side of the pair of fitting structures will be described, and a description of the fitting structure located on the arrow Z2 side of the pair of fitting structures will be omitted.

[0057] 9 and 10 , a fixing portion 76 for fixing the fixing member 70 to the switch unit 18 is formed on the inner case 30. By being formed on the inner case 30, the fixing portion 76 faces the inside of the fixing frame 16. In other words, the fixing portion 76 is exposed to the inside of the fixing frame 16.

[0058] The fixing portion 76 has a first fixing portion 80, a second fixing portion 82, and a snap-fit ​​portion 84. The first fixing portion 80 is formed at a first end portion of the fixing portion 76 on the arrow X1 side, and the second fixing portion 82 is formed at a second end portion of the fixing portion 76 on the arrow X2 side. The first fixing portion 80 and the second fixing portion 82 are located on both sides of the snap-fit ​​portion 84 in the arrow X direction. Specifically, the first fixing portion 80 is located on the arrow X1 side of the snap-fit ​​portion 84, and the second fixing portion 82 is located on the arrow X2 side of the snap-fit ​​portion 84.

[0059] The first fixing portion 80 has a first groove 86 extending in the direction of arrow Z. Similarly, the second fixing portion 82 has a second groove 88 extending in the direction of arrow Z. The first groove 86 and the second groove 88 each penetrate in the direction of arrow Z. Furthermore, the first groove 86 opens on the second groove 88 side (i.e., the arrow X2 side), and the second groove 88 opens on the first groove 86 side (i.e., the arrow X2 side).

[0060] The snap fit portion 84 is formed by an elastic piece extending in the direction of arrow Z. The snap fit portion 84 is located in the center between the first fixing portion 80 and the second fixing portion 82 in the direction of arrow X. A pair of slits 90 is formed on both sides of the snap fit portion 84 in the direction of arrow X. The pair of slits 90 extend in the direction of arrow Z. Each slit 90 penetrates in the direction of arrow Y.

[0061] The end of the snap-fit ​​portion 84 on the arrow Z1 side is a connected end connected to the inner case 30, and the end of the snap-fit ​​portion 84 on the arrow Z2 side is a free end that is not connected to the inner case 30. A protrusion 92 is formed at the free end of the snap-fit ​​portion 84. The protrusion 92 protrudes from the free end of the snap-fit ​​portion 84 in the direction of the arrow Y1.

[0062] As shown in Figures 10 and 11, a fitting portion 78 for fixing the fixing member 70 to the fixing frame 16 is formed on the inner peripheral surface of the fixing frame 16. The fitting portion 78 is formed in a concave shape. The fitting portion 78 is formed adjacent to the opening 68. Specifically, the fitting portion 78 is formed on the peripheral edge of the opening 68 on the inner peripheral surface of the fixing frame 16, on the edge portion on the arrow Z1 side relative to the opening 68. The fitting portion 78 is formed to open on the arrow Z2 side. Note that, because the fitting portion 78 is formed in a concave shape, it is not exposed on the outer peripheral surface of the fixing frame 16. In other words, the fitting portion 78 does not penetrate the fixing frame 16 in the radial direction, but terminates inside the outer peripheral surface of the fixing frame 16.

[0063] Of the inner surfaces of the recessed fitting portion 78, the side surface on the arrow X1 side is formed as a first locking portion 94, and the side surface on the arrow X2 side is formed as a second locking portion 96. The first locking portion 94 and the second locking portion 96 are examples of the "locking portion" according to the technology of the present disclosure.

[0064] Furthermore, an abutment portion 100 is formed on the side surface 98 on the arrow Y2 side of the inner surface of the recessed fitting portion 78. The abutment portion 100 is formed in the center of the side surface 98 in the direction of arrow X, and is formed in the shape of a protrusion that protrudes from the side surface 98 in the direction of arrow Y1.

[0065] As shown in Fig. 12, the fixing member 70 is formed in a plate shape. As an example, the fixing member 70 is made of metal and is configured as a sheet metal member manufactured from sheet metal. The fixing member 70 has a fixed portion 72 and a fitted portion 74. The fixed portion 72 is a portion that is fixed to the fixing portion 76 (see Fig. 10) and is configured as a portion of the fixing member 70 on the arrow Z2 side. The fitted portion 74 is a portion that is fitted into a fitting portion 78 (see Fig. 11) and is configured as a portion of the fixing member 70 on the arrow Z1 side.

[0066] The fixed portion 72 has a first fixed portion 102 and a second fixed portion 104. The first fixed portion 102 is formed by the end portion of the fixed portion 72 on the arrow X1 side, and the second fixed portion 104 is formed by the end portion of the fixed portion 72 on the arrow X2 side.

[0067] The fixed portion 72 also has a notch 106. The notch 106 is formed at the end of the fixed portion 72 on the arrow Z2 side. The notch 106 penetrates in the direction of arrow Y and opens on the arrow Z2 side. The notch 106 is located in the center of the fixed portion 72 in the direction of arrow X.

[0068] The fitted portion 74 has a first hook portion 108, a second hook portion 110, and an elastic portion 112. The first hook portion 108, the second hook portion 110, and the elastic portion 112 are aligned in the direction of the arrow X. As an example, the first hook portion 108 is located on the arrow X1 side of the elastic portion 112, and the second hook portion 110 is located on the arrow X2 side of the elastic portion 112. The elastic portion 112 is located between the first hook portion 108 and the second hook portion 110 in the direction of the arrow X.

[0069] The fitted portion 74 has the first hook portion 108 and the second hook portion 110, but may have one hook portion or may have three or more hook portions. The number of hook portions is not limited. Below, an example will be described in which the fitted portion 74 has the first hook portion 108 and the second hook portion 110. The first hook portion 108 and the second hook portion 110 are an example of "multiple hook portions" according to the technology of the present disclosure.

[0070] A slit 114 is formed between the first hook portion 108 and the elastic portion 112. Similarly, a slit 114 is formed between the second hook portion 110 and the elastic portion 112. Each slit 114 extends along the direction of arrow Z. By forming a pair of slits 114 in the fitted portion 74, the fitted portion 74 is formed with the first hook portion 108, the second hook portion 110, and the elastic portion 112. The first hook portion 108, the second hook portion 110, and the elastic portion 112 are each formed by an elastic piece extending in the direction of arrow Z. The direction of arrow Z is an example of a "direction along a direction intersecting the optical axis" according to the technology of the present disclosure.

[0071] Then, with the switch unit 18 assembled to the fixed frame 16, the switch unit 18 is fixed to the fixed frame 16 using the fixing member 70 in the following manner. First, the first hook portion 108 and the second hook portion 110 are inserted into the first groove 86 and the second groove 88 from the arrow Z2 side. When the first fixed portion 102 and the second fixed portion 104 are inserted into the first groove 86 and the second groove 88 from the arrow Z2 side, the elastic portion 112 comes into contact with the protrusion 92 of the snap fit portion 84, causing the snap fit portion 84 to elastically deform in the arrow Y2 side.

[0072] Then, when the tip ends of the first hook portion 108 and the second hook portion 110 pass through the first groove 86 and the second groove 88, the first fixed portion 102 and the second fixed portion 104 are inserted into the first groove 86 and the second groove 88. The base ends of the first hook portion 108 and the second hook portion 110 are also inserted into the first groove 86 and the second groove 88. Furthermore, when the protrusion 92 climbs over the elastic portion 112 and the fixed portion 72, the snap fit tries to return to its original shape and is deformed in the direction of arrow Y1, and the protrusion 92 is inserted inside the notch 106. As a result, the protrusion 92 is engaged with the notch 106 from the side of arrow Z2. The first fixed portion 102 and the second fixed portion 104 are inserted into the first groove 86 and the second groove 88, and the protrusion 92 is engaged with the notch 106, whereby the fixed portion 72 is fixed to the fixing portion 76. In this way, the fixed portion 72 is fixed to the fixing portion 76 from the arrow Z2 side.

[0073] Furthermore, when the tips of the first hook portion 108 and the second hook portion 110 pass through the first groove 86 and the second groove 88, they are hooked onto the side surface 98 of the fitted portion 74 from the arrow Y1 side. Furthermore, the elastic portion 112 is elastically deformed in the arrow Y1 side by abutting against the abutting portion 100. The abutting portion 100 has a shape that elastically deforms the elastic portion 112 in the arrow Y1 side. The first hook portion 108 and the second hook portion 110 are hooked onto the side surface 98 of the fitted portion 74, and the elastic portion 112 is elastically deformed by abutting against the abutting portion 100, so that the fitted portion 74 is fitted into the fitting portion 78. In this way, the fitted portion 74 is fitted into the fitting portion 78 from the arrow Z2 side. Furthermore, when the fitted portion 74 is fitted into the fitting portion 78, the first hook portion 108 is fitted with the first locking portion 94 from the side indicated by the arrow X2, and the second hook portion 110 is fitted with the second locking portion 96 from the side indicated by the arrow X1. The first hook portion 108 and the second hook portion 110 are examples of the "fitted portion" according to the technology of the present disclosure.

[0074] In this manner, the switch unit 18, when assembled to the fixed frame 16, is fixed to the fixed frame 16 using the fixing member 70. As shown in Fig. 13, when the switch unit 18 is fixed to the fixed frame 16 using the fixing member 70, the elastic portion 112 abuts against the abutting portion 100 and is elastically deformed in the direction of arrow Y1, so that a pulling force F acts on the switch unit 18, pulling it inward of the fixed frame 16 (i.e., toward the direction of arrow Y1).

[0075] As a result of the pulling force F acting on the switch unit 18, the flange portion 38 of the outer case 28 is brought into overlapping engagement with the peripheral edge of the opening 68 from the outside of the fixed frame 16 (i.e., the arrow Y2 side). The first hook portion 108 and the second hook portion 110 are hooked onto the side surface 98 of the fitting portion 78 in a direction that restricts removal of the switch unit 18 from the outside of the fixed frame 16 (i.e., the arrow Y2 side) (see FIG. 9). That is, the switch unit 18 is fixed to the fixed frame 16 with the fixed member 70 and the flange portion 38 sandwiching the fixed frame 16.

[0076] As described above, in the lens device 10, a screwless fitting structure that does not use screws is used as the fixing structure for fixing the switch unit 18 to the fixed frame 16. In addition, in the fitting structure, a fitting portion 78 is formed on the inner peripheral surface of the fixed frame 16, and a structure is adopted in which the fitted portion 74 is fitted into the fitting portion 78 from inside the fixed frame 16. Furthermore, in the fitting structure, the fitting direction of the fitted portion 74 with respect to the fitting portion 78 is set to the direction of arrow Z. The direction of arrow Z is an example of a "direction along a direction intersecting the optical axis" according to the technology of the present disclosure.

[0077] As shown in FIG. 14 , the inner case 30 is formed with a holding portion 116 that holds a portion of the flexible cable 44. The holding portion 116 is formed with a pair of claws 118. As shown in FIG. 15 , the inner case 30 is formed with a plurality of windows 120. Each window 120 opens at a position corresponding to a slide switch 20. Each window 120 faces the inside of the fixed frame 16. That is, each window 120 is exposed to the inside of the fixed frame 16.

[0078] Next, a method for assembling the lens device 10 of this embodiment will be described.

[0079] The method of assembling the lens device 10 of this embodiment includes an assembly step of assembling the lens barrel 12 and an attachment step of attaching the plurality of lenses 14 to the inside of the lens barrel 12. The attachment step includes an assembly step of inserting the inner case 30 into the opening 68 from the outside of the fixed frame 16 and attaching the switch unit 18 to the fixed frame 16, and a fixing step of fixing the switch unit 18 to the fixed frame 16 using a pair of fixing members 70.

[0080] The fixing step includes a fitting step of fixing the pair of fixing members 70 to the respective fixing portions 76 from inside the fixing frame 16 and fitting the fitted portions 74 of the pair of fixing members 70 into the respective fitting portions 78. The fitting step includes elastically deforming the elastic portions 112 of the fitted portions 74 by abutting them against the abutting portions 100 of the fitting portions 78, and hooking the first hook portions 108 and the second hook portions 110 onto the side surfaces 98 of the fitted portions 74. The method of assembling the lens device 10 of this embodiment is an example of a "method of manufacturing a lens device" according to the technology of the present disclosure.

[0081] Next, the effects of this embodiment will be described.

[0082] (1) As described above in detail, in the lens device 10 according to this embodiment, the fixing member 70 is used to fix the switch unit 18 to the fixing frame 16. The fixing frame 16 has a fitting portion 78, and the fixing member 70 has a fixed portion 72 that is fixed to the fixing portion 76 of the switch unit 18, and a fitted portion 74 that fits into the fitting portion 78. Therefore, by fixing the fixed portion 72 of the fixing member 70 to the fixing portion 76 and fitting the fitted portion 74 of the fixing member 70 into the fitting portion 78, the switch unit 18 can be fixed to the fixing frame 16.

[0083] (2) The fitted portion 74 has an elastic portion 112 having elasticity, and the fitting portion 78 has an abutting portion 100 that abuts against the elastic portion 112 and elastically deforms the elastic portion 112. Therefore, for example, compared to when the fitted portion 74 fits into the fitting portion 78 without elastic deformation of the elastic portion 112, the elastic deformation of the elastic portion 112 allows the fitted portion 74 to fit firmly into the fitting portion 78. As a result, screws are not required to fix the switch unit 18 to the fixed frame 16.

[0084] (3) The fixing structure for fixing the fixed frame 16 and the switch unit 18 is a fitting structure using a fitting portion 78 and a fitted portion 74. Therefore, since there is no need to use screws to fix the switch unit 18 to the fixed frame 16, it is possible to avoid various problems caused by screws loosening over time. Furthermore, it is possible to avoid various problems caused by using screws, as explained in (4) to (6) below.

[0085] (4) For example, if screws are used to secure the switch unit 18 to the fixed frame 16 and the switch unit 18 is further secured to the fixed frame 16 by screws from the outside of the fixed frame 16, the screws will be exposed to the outside of the fixed frame 16, which may impair the appearance of the area surrounding the switch unit 18. In contrast, if screws are not used to secure the switch unit 18 to the fixed frame 16, it is possible to avoid impairing the appearance of the area surrounding the switch unit 18.

[0086] (5) For example, when fixing the switch unit 18 to the fixed frame 16 with screws from inside the fixed frame 16 to avoid impairing the appearance of the area around the switch unit 18, a screwdriver is inserted into the inside of the fixed frame 16 from a direction oblique to the optical axis of the fixed frame 16 and the screw is tightened with the screwdriver. However, in this case, when inserting the screwdriver inside the fixed frame 16, there is a risk that the tip of the screwdriver may hit the fixed frame 16 and scratch it, or that the tip of the screwdriver may get caught on the flexible cable 44 and damage the flexible cable 44. In contrast, when screws are not used to fix the switch unit 18 to the fixed frame 16, it is possible to avoid the tip of the screwdriver hitting the fixed frame 16 and scratching it, or that the tip of the screwdriver may get caught on the flexible cable 44 and damage the flexible cable 44.

[0087] (6) For example, when the switch unit 18 is fixed to the fixed frame 16 using screws at multiple positions spaced apart in the circumferential direction of the fixed frame 16, the tightening force of the screws at multiple positions may deteriorate the roundness of the fixed frame 16, which may reduce the operability of an operation ring (not shown) provided on the lens device 10. In contrast, when screws are not used to fix the switch unit 18 to the fixed frame 16, it is possible to prevent the roundness of the fixed frame 16 from being deteriorated, and therefore it is possible to prevent the operability of the operation ring from being reduced.

[0088] (7) The switch unit 18 has an outer case 28 arranged facing the outside of the fixed frame 16 and an inner case 30 arranged facing the inside of the fixed frame 16, and the fixed frame 16 has an opening 68. The outer shape of the outer case 28 is larger than the opening 68, and the outer shape of the inner case 30 is smaller than the opening 68. Therefore, even if the outer case 28 and the inner case 30 are assembled to form the switch unit 18 as a unit at a stage before the switch unit 18 is assembled to the fixed frame 16, the switch unit 18 can still be assembled to the fixed frame 16.

[0089] (8) The outer case 28 has an overlapping portion that overlaps the periphery of the opening 68 from the outside of the fixed frame 16. Therefore, when the switch unit 18 is assembled to the fixed frame 16, the outer case 28 can be prevented from rattling relative to the fixed frame 16. This improves the ease of fitting the fitted portion 74 into the fitting portion 78 when the switch unit 18 is assembled to the fixed frame 16. Furthermore, the overlapping portion can prevent a gap from being formed between the outer case 28 and the fixed frame 16, thereby preventing foreign matter from entering between the outer case 28 and the fixed frame 16.

[0090] (9) The switch section unit is assembled as a unit before the inner case 30 and the case section 34 are inserted into the opening 68. Therefore, the workability of assembly can be improved compared to, for example, when the switch unit 18 is not assembled as a unit before the inner case 30 is inserted into the opening 68 and the components of the switch unit 18 (e.g., the outer case 28 and the inner case 30, etc.) are assembled separately to the fixed frame 16.

[0091] (10) The switch unit 18 has windows 120 that open at positions corresponding to the slide switches 20. The windows 120 are formed in the inner case 30 that is disposed facing the inside of the fixed frame 16. Therefore, when the switch unit 18 is assembled to the fixed frame 16, the positions of the operating parts 24 of the slide switches 20 can be confirmed from inside the fixed frame 16 through the windows 120.

[0092] (11) A pair of fixing members 70 are used to fix the switch unit 18 to the fixed frame 16. One of the pair of fixing members 70 is fixed to a fixing portion 76 provided at a first end of the inner case 30, and the other of the pair of fixing members 70 is fixed to a fixing portion 76 provided at a second end of the inner case 30. Therefore, the switch unit 18 can be fixed to the fixed frame 16 at two locations, the first end and the second end of the inner case 30. This makes it possible to fix the switch unit 18 to the fixed frame 16 more stably than, for example, when the switch unit 18 is fixed to the fixed frame 16 at one location. Furthermore, compared to, for example, when a single fixing member configured by connecting the pair of fixing members 70 (i.e., a single fixing member extending from one fixing portion 76 to the other fixing portion 76 in the arrow Z direction) is used, the space required to arrange the pair of fixing members 70 can be reduced, thereby enabling the lens device 10 to be made more compact.

[0093] (12) The switch unit 18 has a fixing portion 76, and the fixing member 70 has a fixed portion 72 that is fixed to the fixing portion 76. A snap-fit ​​structure using a snap-fit ​​portion 84 that is an elastic piece is applied to the fixing portion 76. Therefore, for example, compared to when a snap-fit ​​structure is not applied to the fixing portion 76, the fixed portion 72 can be more firmly fixed to the fixing portion 76, and therefore it is possible to prevent the fixing member 70 from coming off the switch unit 18 due to impact, deterioration over time, or the like.

[0094] (13) The fixing portion 76 provided on the switch unit 18 faces the inside of the fixing frame 16. Therefore, compared to when the fixing portion 76 faces the outside of the fixing frame 16, for example, it is possible to avoid impairing the appearance of the peripheral portion of the switch unit 18.

[0095] (14) The fixing portion 76 has a first fixing portion 80 formed at a first end portion of the fixing portion 76 on the arrow X1 side and a second fixing portion 82 formed at a second end portion of the fixing portion 76 on the arrow X2 side, and the fixing portion 72 has a first fixing portion 102 fixed to the first fixing portion 80 and a second fixing portion 104 fixed to the first fixing portion 80. Therefore, for example, the fixing portion 72 can be fixed to the fixing portion 76 more stably than when the fixing portion 72 is fixed to the fixing portion 76 at one point.

[0096] (15) The fitting portion 78 is formed on the inner peripheral surface of the fixed frame 16 and is not exposed on the outer peripheral surface of the fixed frame 16. Therefore, for example, compared to when the fitting portion 78 is exposed on the outer peripheral surface, it is possible to avoid impairing the appearance of the periphery of the switch unit 18.

[0097] (16) The mating direction of the mated portion 74 with respect to the mating portion 78 is set to the direction of arrow Z. Therefore, for example, an operator can mating the mated portion 74 with the mating portion 78 by pushing the fixing member 70 in the direction of arrow Z with their fingers.

[0098] (17) The fitting portion 78 is formed in a concave shape. Therefore, for example, compared to when the fitting portion 78 is formed in a convex shape, the fitting portion 78 can be prevented from protruding inward from the fixed frame 16.

[0099] (18) The fitting portion 78 has a first locking portion 94 and a second locking portion 96, and the fitted portion 74 has a first hook portion 108 and a second hook portion 110 that engage with the first locking portion 94 and the second locking portion 96 in the direction of arrow X. Therefore, when the fitted portion 74 is fitted into the fitting portion 78, it is possible to prevent the fitted portion 74 from rattling in the direction of arrow X relative to the fitting portion 78.

[0100] (19) The contact portion 100 has a shape that elastically deforms the elastic portion 112 in a direction that draws the switch unit 18 toward the inside of the fixed frame 16. Therefore, when the elastic portion 112 comes into contact with the contact portion 100, the elastic portion 112 can generate a drawing force F that draws the switch unit 18 toward the inside of the fixed frame 16. This allows the switch unit 18 to be fixed to the fixed frame 16 in a state where it is drawn toward the inside of the fixed frame 16.

[0101] (20) The fitted portion 74 has a first hook portion 108 and a second hook portion 110 that can be hooked onto the fitting portion 78. Therefore, by hooking the first hook portion 108 and the second hook portion 110 onto the fitting portion 78, the first hook portion 108 and the second hook portion 110 can prevent the switch unit 18 from slipping out to the outside of the fixed frame 16. Furthermore, because the fitting portion 78 can be hooked onto the first hook portion 108 and the second hook portion 110 at two locations, the first hook portion 108 and the second hook portion 110, the force preventing the switch unit 18 from slipping out can be increased compared to, for example, when the fitting portion 78 is hooked onto the fitting portion 78 at one location.

[0102] (21) The first hook portion 108 is aligned with the elastic portion 112 on the arrow X1 side, and the second hook portion 110 is aligned with the elastic portion 112 on the arrow X2 side. Therefore, by positioning the first hook portion 108 and the second hook portion 110 on both sides of the elastic portion 112 in the arrow X direction, a balanced retaining force on the switch unit 18 can be exerted compared to, for example, when one side of the elastic portion 112 is hooked onto the fitting portion 78.
