[0022] (About the housing 20)
[0023] The housing 20 is formed into a roughly double-layered cylindrical shape with the front-rear direction as the axial direction. That is, the housing 20 has an outer cylinder 20A and an inner cylinder 20B, and the inner cylinder 20B is arranged on the radial inner side of the outer cylinder 20A. In addition, the second direction ends of the front ends of the outer cylinder 20A and the inner cylinder 20B are connected to each other. A pair of fixing pieces 20C are formed on the outer periphery of the outer cylinder 20A on both sides in the first direction. When viewed from the second direction, the fixing pieces 20C are inclined toward the front side as they approach the radial outer side of the housing 20. In addition, the fixing pieces 20C are engaged with the instrument panel of the vehicle, etc., and the housing 20 (that is, the switch device 10) is fixed to the vehicle. A fitting recess 20D is formed at the inner periphery of the rear end of the outer cylinder 20A, which is one layer lower toward the radial outer side. The inner cylinder 20B is formed into a roughly bottomed cylindrical shape that is open to the front side, and the rear wall of the inner cylinder 20B is located at a position closer to the front side than the rear end of the outer cylinder 20A. In addition, a hole portion through which a part of a rubber contact member 50 described later is exposed and a hole portion through which a lens 56 is inserted are appropriately formed in the rear wall of the inner cylinder 20B.
[0024] A bezel 22 is mounted on the front end of the housing 20. Specifically, a cylindrical fitting tube 20E is provided on the front end of the housing 20, and the fitting tube 20E protrudes forward from the front end of the outer tube 20A. The bezel 22 is formed into a substantially cylindrical shape with the front-rear direction as the axial direction. The bezel 22 is externally inserted into the fitting tube 20E and is mounted on the outer tube 20A by claw fitting so as to be relatively immovable.
[0025] (About subject 30)
[0026] like Figure 2 to Figure 7As shown, the main body 30 is formed into a substantially bottomed cylindrical shape with the front-rear direction as the axial direction and open to the front side. The main body 30 is inserted into the housing 20 from the rear side and is mounted to the housing 20 by means of claw engagement so as to be unable to move relatively. When the main body 30 is mounted to the housing 20, the inner cylinder 20B is located inside the main body 30. That is, the front portion of the main body 30 is arranged between the outer cylinder 20A and the inner cylinder 20B, and the main body 30 is covered by the outer cylinder 20A from the radial outside. In addition, the rear surface of the main body 30 is arranged at a position flush with the rear end surface of the outer cylinder 20A. A step portion 30A that is one level higher toward the radial outside is formed on the outer peripheral portion of the rear end portion of the main body 30, and the step portion 30A is embedded in the fitting recess 20D of the housing 20.
[0027] The front end of the main body 30 constitutes the skeleton part 30B. The skeleton part 30B is formed into a concave shape that is open to the radial outer side of the main body 30 and extends along the circumferential direction of the skeleton part 30B. The interior of the skeleton part 30B is set as an antenna wire accommodating part 30B1, and the antenna wire 60 described later is wound around the skeleton part 30B in the antenna wire accommodating part 30B1. When the main body 30 is installed in the shell 20, the rear end of the skeleton part 30B abuts against the inner circumferential surface of the outer cylinder 20A, and the main body 30 is arranged on the radial outer side of the inner cylinder 20B with a predetermined gap. That is, it becomes a structure that restricts the movement of the main body 30 in the radial direction by the outer cylinder 20A and the inner cylinder 20B.
[0028] An opening 30C is formed at the side wall of the main body 30 at the other end in the second direction. The opening 30C is formed in a groove shape with the longitudinal direction being the front-rear direction and penetrating in the radial direction (the second direction), and the front end of the opening 30C is open to the front side (refer to Figure 5 to Figure 7 ). That is, a part of the frame part 30B is cut away through the opening part 30C, and the inside of the opening part 30C is connected to the antenna wire accommodating part 30B1. The opening part 30C is formed from the frame part 30B to the step part 30A, and the rear end of the opening part 30C constitutes an opening exposed part 30C1 for arranging the antenna connecting part 42A of the substrate 42 described later and exposing the antenna connecting part 42A. The width dimension of the opening exposed part 30C1 is set to be larger than the width dimension of the opening part 30C.
[0029] A restriction portion 20F (see FIG. 2 ) is formed on the outer periphery of the inner tube 20B of the housing 20 at the other end portion in the second direction (a position corresponding to the opening 30C). Figure 2 and Figure 4 The limiting portion 20F is formed into a columnar shape extending in the front-to-back direction, and is formed from the front end portion to the rear end portion of the inner tube 20B. The width dimension of the limiting portion 20F is set to be slightly smaller than the width dimension of the opening portion 30C, and the limiting portion 20F is embedded in the opening portion 30C and engaged with the main body 30 in the circumferential direction of the main body 30.
[0030] A plurality of installation ribs 30D for installing a base plate 42 described later are provided on the rear wall of the main body 30. The installation ribs 30D protrude forward from the rear wall and are located on the rear side of the inner tube 20B. The installation rib 30D at one location is formed into a substantially rectangular plate shape with the second direction as the plate thickness direction, and is arranged close to the second direction side of the opening exposed portion 30C1 in a manner that closes the rear portion of the opening exposed portion 30C1 from the second direction side (see Figure 2 and Figure 5 A connector portion 30E is provided at a substantially central portion of the rear wall of the main body 30. The connector portion 30E is formed in a substantially rectangular cylindrical shape with the front-rear direction as an axial direction, and protrudes from the rear wall of the main body 30 to the rear side.
[0031] (Regarding the switch mechanism 40)
[0032] like Figure 2 , Figure 3 as well as Figure 5 As shown, the switch mechanism 40 is accommodated inside the main body 30. The switch mechanism 40 is configured to include a substrate 42, a rubber contact member 50, a sliding member 52, and a lens 56.
[0033] (Regarding substrate 42)
[0034] like Figure 6 As also shown in FIG. 1 , the base plate 42 is formed into a roughly circular plate shape with the front-to-back direction being the plate thickness direction. The base plate 42 is accommodated in the rear end side portion of the main body 30, and is sandwiched by the setting rib 30D of the main body 30 and the rear wall of the inner tube 20B of the shell 20 in the front-to-back direction, and is fixed to the shell 20 and the main body 30.
[0035] Fixed contacts 43 are provided at both ends in the first direction of the front surface of the substrate 42. An illumination LED (light emitting diode) 44 is provided at the approximate center of the front surface of the substrate 42, and an indication LED 45 is provided at one end in the second direction of the front surface of the substrate 42. The illumination LED 44 and the indication LED 45 form a structure that emits light to the front side.
[0036] A plurality of (eight in the present embodiment) connector terminals 46 as connector terminals extending in the front-to-back direction are provided on the rear surface of the substrate 42. Four connector terminals 46 are arranged in a manner arranged in a first direction, with the connector terminals 46 arranged in the first direction forming a group, and two groups of connector terminals 46 are arranged in a manner arranged in a second direction. The front end portion of the connector terminal 46 is bent outward in the second direction and connected to the rear surface of the substrate 42. The rear end portion of the connector terminal 46 protrudes rearward from the rear wall of the main body 30 and is arranged in the connector portion 30E. It should be noted that a through hole is formed through the rear wall of the main body 30 for the connector terminal 46 to be inserted. In addition, the external connector inserted into the connector portion 30E is connected to the connector terminal 46, and the substrate 42 is electrically connected to the control portion of the vehicle.
[0037] A pair of antenna connection parts 42A are integrally provided at the end of the other side in the second direction of the substrate 42. The radial cross-section of the pair of antenna connection parts 42A is rectangular, and the pair of antenna connection parts 42A protrude radially outward (the other side in the second direction) from the outer peripheral portion of the substrate 42, and are arranged along the first direction. The pair of antenna connection parts 42A are arranged in the approximately central portion of the opening exposed portion 30C1 of the main body 30, and before the housing 20 is mounted on the main body 30, the antenna connection parts 42A are exposed radially outward through the opening exposed portion 30C1 (refer to Figure 5 and Figure 7 On the other hand, after the housing 20 is mounted on the main body 30, the antenna connection portion 42A is covered by the outer tube 20A of the housing 20 from the radially outer side (see Figure 2 ). In addition, the width dimensions of the antenna connection portion 42A and the opening portion 30C are set so that when viewed from the front side, the pair of antenna connection portions 42A are arranged in the opening portion 30C (refer to Figure 4 ). Specifically, the distance between the side surface on the first direction side of the antenna connection part 42A on one side of the first direction and the side surface on the first direction side of the antenna connection part 42A on the other side of the first direction is set to be slightly shorter than the width dimension of the opening portion 30C. The surface of the antenna connection part 42A is pre-plated, and the antenna connection part 42A and the connector terminal 46 are connected by a pattern formed on the substrate 42. That is, the antenna connection part 42A is conductive with the connector terminal 46. In addition, by plating the surface of the antenna connection part 42A having a radial cross-section rectangle, the corners of the radial cross-section rectangle of the antenna connection part 42A can be removed to form a smoother shape, and the load applied to the antenna wire 60 when the antenna wire 60 is wound around the antenna connection part 42A can be reduced.
[0038] (Regarding the rubber contact member 50)
[0039] like Figure 2 , Figure 3 as well as Figure 5As shown, the rubber contact 50 has a base portion 50A, which is formed in a plate shape with the front-to-back direction as the plate thickness direction, and is arranged in an adjacent manner on the front side of the substrate 42. A pair of switch portions 50B are formed at the base portion 50A at positions corresponding to the fixed contacts 43 of the substrate 42. The switch portion 50B is formed in a substantially dome shape that bulges from the rubber contact 50 to the front side, and a movable contact (not shown) is provided inside the switch portion 50B. And, a structure is formed in which the switch portion 50B is operated by pressing the switch portion 50B to the rear side (the fixed contact 43 side). Specifically, it is configured so that the movable contact contacts the fixed contact 43 to turn on the switch portion 50B.
[0040] The base part 50A is provided with a lighting cylinder 50C at a position corresponding to the lighting LED 44. The lighting cylinder 50C is formed in a substantially rectangular cylinder shape and protrudes forward from the rubber contact 50, and the interior of the lighting cylinder 50C is penetrated in the front-back direction. The base part 50A is provided with an indication cylinder 50D at a position corresponding to the indication LED 45. The indication cylinder 50D is formed in a substantially rectangular cylinder shape and protrudes forward from the rubber contact 50.
[0041] (Regarding Slider 52)
[0042] The slider 52 is formed in a substantially rectangular cylindrical shape with the front-rear direction as the axial direction. The slider 52 is inserted into the inner cylinder 20B of the housing 20 and is connected to the inner cylinder 20B in a manner that allows sliding along the front-rear direction. That is, the slider 52 is accommodated in the main body 30 in a manner that allows sliding along the front-rear direction. When the slider 52 is accommodated in the main body 30, the front end of the slider 52 protrudes to the front side than the main body 30 and the housing 20.
[0043] A switch pressing portion 52A is formed on the side wall of the slider 52 at a position corresponding to the switch portion 50B of the rubber contact member 50. The switch pressing portion 52A is formed in a substantially cross-shaped columnar shape extending in the front-to-back direction, and is disposed adjacently to the front side of the switch portion 50B. In addition, a lens accommodating portion 52B for accommodating a lens 56 described later is formed on a portion on one side of the slider 52 in the second direction. The lens accommodating portion 52B is formed in a substantially rectangular cylindrical shape with the front-to-back direction as an axial direction, and is disposed at a position overlapping with the indication LED 45 in a front view.
[0044] A knob portion 52C is integrally provided at the front end of the slider 52. The knob portion 52C is formed in a substantially circular plate shape with the front-rear direction being the plate thickness direction, and protrudes from the outer periphery of the slider 52 in a manner that covers the main body 30 and the inner cylinder 20B from the front side. A substantially rectangular lens hole 52D is formed through a portion of the knob portion 52C on one side in the second direction. In addition, an illumination hole 52E is formed through a substantially central portion of the knob portion 52C. The illumination hole 52E is formed in a substantially rectangular shape and is arranged at a position overlapping with the illumination LED 44 in a front view.
[0045] A decorative panel 54 is provided on the front side of the knob portion 52C, and the decorative panel 54 is made of a light-transmitting resin material. The decorative panel 54 is formed into a circle corresponding to the knob portion 52C in a front view, and is formed into a concave shape that is open to the rear side. In addition, the decorative panel 54 is fixed integrally with the knob portion 52C by two-color molding. The decorative panel 54 is arranged on the radial inner side of the cover ring 22, and is exposed to the cabin side of the vehicle in an operable manner. Thus, the following structure is formed: by the operator pressing the decorative panel 54 to the rear side, the slider 52 slides to the rear side, and the switch portion 50B of the switch mechanism 40 works.
[0046] The decorative panel 54 has an indication hole 54A formed through it at a position corresponding to the lens hole 52D of the knob portion 52C. In addition, a display mark 54B composed of characters, marks, etc. is formed on the decorative panel 54, and the display mark 54B is located in front of the lighting hole 52E of the knob portion 52C. The display mark 54B is formed, for example, by painting the front surface of the decorative panel 54 black and removing the symbol corresponding to the display mark 54B by laser processing. Thus, it is configured that the light emitted by the lighting LED 44 passes through the slider 52 and the lighting hole 52E to illuminate the display mark 54B.
[0047] (About lens 56)
[0048] The lens 56 is made of a transparent resin material that can transmit light. The lens 56 is formed into a roughly long strip with the second direction as the plate thickness direction and the front-to-back direction as the long dimension direction. In addition, the lens 56 is inserted into the lens accommodating portion 52B of the sliding member 52 from the rear side and is installed on the sliding member 52 by claw engagement. An indication portion 56A is provided at the front end portion of the lens 56. The indication portion 56A is inserted into the lens hole 52D of the knob portion 52C and the indication hole 54A of the decorative panel 54 from the rear side, and is exposed from the decorative panel 54 to the front side. The lens 56 is located in front of the indication LED 45, and the light emitted by the indication LED 45 is guided to the front side by the lens 56, lighting the indication portion 56A.
[0049] (About antenna wire 60)
[0050] like Figure 2 to Figure 5as well as Figure 7 As shown, the antenna wire 60 is wound around the skeleton portion 30B of the main body 30 along the circumferential direction and arranged in the antenna wire accommodating portion 30B1. That is, the antenna wire 60 is wound around the skeleton portion 30B between the outer cylinder 20A and the inner cylinder 20B of the housing 20. One end 60A and the other end 60B of the antenna wire 60, which are ends, extend rearward from the antenna wire accommodating portion 30B1 and are arranged in the opening portion 30C of the main body 30. In addition, one end 60A of the antenna wire 60 is wound around and soldered to one antenna connecting portion 42A on the substrate 42, and the other end 60B of the antenna wire 60 is wound around and soldered to another antenna connecting portion 42A on the substrate 42. That is, the one end 60A and the other end 60B of the antenna wire 60 are directly connected to the substrate 42, and the antenna wire 60 is electrically connected to the connector terminal 46.
[0051] (Effect)
[0052] Next, the operation and effects of the switch device 10 according to the present embodiment will be described.
[0053] In the non-operating state of the switch device 10 constructed as described above, the slide member 52 is arranged in the initial position ( Figure 2 and Figure 3 4. The position shown in FIG. 4 ). Furthermore, when the decorative panel 54 of the sliding member 52 is pressed, the sliding member 52 slides to the rear side. As a result, the switch pressing portion 52A of the sliding member 52 presses the pair of switch portions 50B of the rubber contact member 50. As a result, the movable contacts of the pair of switch portions 50B contact the fixed contacts 43 of the substrate 42, the pair of switch portions 50B are turned on, and the turn-on signal is output to the control unit of the vehicle. On the other hand, when the operation of the sliding member 52 is released, the sliding member 52 slides to the front side by the restoring force of the switch portion 50B of the rubber contact member 50. As a result, the knob portion 52C is reset to the initial position.
[0054] Furthermore, the control unit of the vehicle is connected to the portable device held by the operator through communication, and by operating the switch device 10 in a state where the authentication between the control unit and the portable device is completed, the control unit starts or stops the engine (power unit) of the vehicle. In addition, the switch device 10 has an antenna wire 60. Therefore, when the battery of the portable device held by the operator is exhausted and communication with the portable device is impossible, communication with the portable device can be performed by forwarding communication. In detail, when the portable device is placed on the decorative panel 54 of the switch device 10, the portable device receives the starting radio wave sent from the coil-shaped antenna wire 60 of the switch device 10, and the coil part in the repeater of the portable device generates an electromotive force. The portable device uses the power to send an ID signal to the authentication device of the vehicle, thereby enabling communication between the authentication device of the vehicle and the portable device.
[0055] Here, the switch device 10 has a cylindrical main body 30. A skeleton portion 30B is provided at the front end portion of the main body 30, and an antenna wire 60 is wound around the skeleton portion 30B. In addition, a substrate 42 is arranged inside the main body 30, and a connector terminal 46 is provided on the rear surface of the substrate 42. Moreover, an antenna connecting portion 42A that is conductive with the connector terminal 46 is provided on the substrate 42, and one end 60A and the other end 60B of the antenna wire 60 are soldered to the antenna connecting portion 42A. As a result, compared with a main body in which the connector terminal is insert-molded as in the prior art, the main body 30 can be manufactured at a low cost, and the antenna wire 60 can be connected to the connector terminal 46. That is, by directly connecting the antenna wire 60 to the substrate 42 provided with the connector terminal 46, the main body 30 can be manufactured at a low cost. Therefore, the manufacturing cost of the switch device 10 can be reduced.
[0056] In addition, an opening portion 30C is formed on the side wall of the main body 30 and penetrates in the radial direction, and the antenna connection portion 42A is exposed to the radial outside of the main body 30 through the opening portion 30C. Thus, the one end 60A and the other end 60B of the antenna wire 60 wound on the skeleton portion 30B can be connected to the antenna connection portion 42A exposed from the opening portion 30C. Thus, the workability during installation of the switch device 10 can be improved. Therefore, the manufacturing cost of the switch device 10 can be further reduced.
[0057] In addition, the skeleton part 30B is formed into a concave shape open to the radial outer side of the main body 30, and the interior of the skeleton part 30B is set as an antenna wire accommodating part 30B1. And the antenna wire accommodating part 30B1 is connected to the opening part 30C. Thus, the one end 60A and the other end 60B of the antenna wire 60 wound on the skeleton part 30B can be led out from the antenna wire accommodating part 30B1 to the rear side and arranged in the opening part 30C to connect the one end 60A and the other end 60B to the antenna connecting part 42A exposed from the opening part 30C (opening exposed part 30C1). In addition, the opening part 30C can be used to clearly grasp the part of the one end 60A and the other end 60B that is led out from the antenna wire 60 wound on the skeleton part 30B. As a result, the operability of the switch device 10 during installation can be further improved. Therefore, the manufacturing cost of the switch device 10 can be further reduced.
[0058] Furthermore, the antenna connection portion 42A protrudes from the outer peripheral portion of the substrate 42 toward the radially outer side of the main body 30, and is disposed in the opening exposed portion 30C1 of the opening portion 30C. Thus, the one end portion 60A and the other end portion 60B of the antenna wire 60 can be soldered to the antenna connection portion 42A while the antenna connection portion 42A is disposed radially outward from the inner peripheral surface of the main body 30. Therefore, the workability when soldering the antenna wire 60 to the antenna connection portion 42A can be further improved.
[0059] In the main body 30, the width of the opening exposed portion 30C1 is wider than the width of the opening portion 30C, and the antenna connection portion 42A is disposed in the opening exposed portion 30C1. This ensures the rigidity of the main body 30 and a sufficient working area for soldering the antenna wire 60 to the antenna connection portion 42A.
[0060] In addition, the opening 30C is formed in a groove shape extending in the front-to-back direction, and the front end of the opening 30C is open to the front side at the front end of the main body 30. Thus, in the process of installing the substrate 42 and the antenna wire 60 on the main body 30, the substrate 42 can be first arranged on the front side of the main body 30 (see Figure 6 ), from this state, the antenna connection part 42A is inserted into the opening part 30C from the front side, and the substrate 42 is accommodated in the main body 30. That is, the substrate 42 can be accommodated in the main body 30 while suppressing the interference of the antenna connection part 42A with the main body 30 through the opening part 30C. In addition, after accommodating the substrate 42 in the main body 30, the antenna wire 60 can be wound around the skeleton part 30B, and then the one end 60A and the other end 60B of the antenna wire 60 can be connected to the antenna connection part 42A arranged in the opening exposed part 30C1 by soldering (refer to Figure 7 ). Thus, the workability during installation of the switch device 10 can be effectively improved. Therefore, the manufacturing cost of the switch device 10 can be effectively reduced.
[0061] Furthermore, as described above, the antenna connection portion 42A protrudes radially outward from the outer peripheral portion of the substrate 42, and the one end portion 60A and the other end portion 60B of the antenna wire 60 are soldered to the antenna connection portion 42A. That is, the antenna connection portion 42A constitutes a part of the substrate 42, the surface of the antenna connection portion 42A is plated, and the antenna connection portion 42A is electrically connected to the connector terminal 46 through a pattern. Thus, compared with a structure in which, for example, a connection terminal for connecting the antenna wire 60 to the substrate 42 is separately provided on the substrate 42, the substrate 42 can be manufactured at a low cost.
[0062] In addition, the main body 30 is fixed to the housing 20. The housing 20 is configured to include an outer cylinder 20A covering the main body 30 from the radially outer side and an inner cylinder 20B arranged inside the main body 30, and the slider 52 is connected to the inner cylinder 20B in a manner that can slide along the front-back direction. As a result, it is not necessary to provide a structure for slidably connecting the slider 52 on the main body 30. Therefore, the main body 30 having the skeleton part 30B can be set to a simple structure. In other words, the shape of the main body 30 can be suppressed from being complicated. As a result, it can further contribute to the cost reduction of the main body 30.
[0063] In addition, the skeleton part 30B is arranged between the outer cylinder 20A and the inner cylinder 20B of the housing 20. That is, the antenna wire 60 is arranged between the outer cylinder 20A and the inner cylinder 20B, and is covered by the outer cylinder 20A from the radially outer side. Thus, for example, the waterproofness and dustproofness of the antenna wire 60 can be improved. Therefore, the reliability of the switch device 10 can be improved.
[0064] Furthermore, after the main body 30 is mounted on the housing 20, the antenna connection portion 42A is covered from the radially outer side by the outer tube 20A of the housing 20. Thus, even if the antenna connection portion 42A is configured to be exposed from the main body 30 through the opening 30C, the housing 20 can ensure the waterproofness and dustproofness of the antenna connection portion 42A.
[0065] In addition, when the main body 30 is mounted on the housing 20, the rear end of the skeleton portion 30B abuts against the inner circumferential surface of the outer cylinder 20A, and the main body 30 is arranged radially outside the inner cylinder 20B with a predetermined gap, and the movement of the main body 30 in the radial direction is restricted by the outer cylinder 20A and the inner cylinder 20B. Thus, even if a part of the side wall of the main body 30 is cut away through the opening 30C, the deformation of the side wall in the radial direction can be suppressed by the housing 20.
[0066] In addition, a limiting portion 20F is formed at the outer peripheral portion of the inner tube 20B of the housing 20 at the end portion on the other side in the second direction, and the limiting portion 20F is embedded in the opening portion 30C and engaged with the main body 30 in the circumferential direction of the main body 30. Thus, even if a part of the side wall of the main body 30 is cut away through the opening portion 30C, the deformation of the side wall in the circumferential direction can be suppressed by the limiting portion 20F. In addition, by forming the limiting portion 20F on the outer peripheral portion of the inner tube 20B, the limiting portion 20F can be embedded in the opening portion 30C while suppressing interference between the antenna wire 60 wound on the skeleton portion 30B and the limiting portion 20F.
[0067] Furthermore, the antenna connection portion 42A is formed integrally with the substrate 42 so as to protrude radially outward from the outer peripheral portion of the substrate 42. Thus, the antenna connection portion 42A does not require other components such as terminals, and the manufacturing cost can be further reduced.
[0068] It should be noted that in this embodiment, "soldering" is used as a method for fixing the one end 60A and the other end 60B of the antenna wire 60 to the antenna connecting portion 42A, but the method for fixing the antenna wire 60 to the antenna connecting portion 42A is not limited to this. For example, the antenna wire 60 and the antenna connecting portion 42A may also be fixed by a method such as "welding".
[0069] In addition, in the present embodiment, the one end portion 60A and the other end portion 60B of the antenna wire 60 are wound around the antenna connection portion 42A and fixed by soldering, but the method of connecting the antenna wire 60 to the antenna connection portion 42A is not limited thereto. For example, a through hole may be formed in the antenna connection portion 42A, and the one end portion 60A or the other end portion 60B of the antenna wire 60 may be inserted through the through hole and fixed by soldering.
[0070] In addition, in the present embodiment, the antenna wire 60 is electrically connected to the connector terminal 46 by providing the antenna connection portion 42A on the outer periphery of the substrate 42 and soldering the one end 60A and the other end 60B of the antenna wire 60 to the antenna connection portion 42A, but the method of connecting the antenna wire 60 to the connector terminal 46 is not limited thereto. For example, although not shown in the figure, it is also possible to provide a connection terminal that is conductive with the connector terminal 46 on the substrate 42, expose one end of the connection terminal from the opening 30C, and solder the one end 60A and the other end 60B of the antenna wire 60 to one end of the connection terminal. In this case, the connection terminal corresponds to the antenna connection portion of the present application.
