Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, the stud pin is inserted through a sheet metal to which the stud pin itself is fixed, and a first substrate and a second substrate along the sheet metal above and below the sheet metal. That is, the stud pin positions the first substrate and the second substrate with respect to the sheet metal.

[0005] Here, in a housing such as an electronic device, a plurality of substrates may be arranged inside. A connector for electrically connecting the plurality of substrates to each other is arranged. Such a housing structure requires positioning of the substrates as described above in order to ensure the connection state of each connector. On the other hand, in the housing structure, in order to improve the assembly accuracy, it is desired to also position members such as an outer housing that have a different orientation from the substrates. However, in the housing structure, in order to position a large number of members, the number of parts increases, and thus the assemblability tends to deteriorate.

[0006] An object of the present invention is to provide a housing structure capable of positioning a large number of members having different orientations.

Means for Solving the Problems

[0007] To achieve the above objective, a housing structure according to one aspect of the present invention comprises a reference member, a pin member fixed to the reference member and extending in a predetermined direction, a first positioning hole provided in a plurality of first members through which the pin member is inserted, and a second positioning hole provided in a second member arranged in a different orientation from the first member through which the pin member is inserted. [Effects of the Invention]

[0008] According to the present invention, it is possible to position multiple members with different orientations. [Brief explanation of the drawing]

[0010] Hereinafter, embodiments for carrying out the invention (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiments described below. Furthermore, the components in the embodiments described below include those that are easily conceivable by those skilled in the art, those that are substantially the same, and those that fall within the so-called equivalent range. Moreover, the components disclosed in the embodiments described below can be combined as appropriate.

[0011] As shown in Figures 1 to 3, the housing structure according to this embodiment is applied to an electronic device 1, which is mounted inside a vehicle and is, for example, a navigation system or an audio system. The electronic device 1 has a housing 2 and a display panel 3.

[0012] The enclosure 2 has an open front and is enclosed on the top, bottom, right, left, and rear sides with sheet metal. Therefore, the enclosure 2 has an outer shell consisting of an upper plate 2A, a lower plate 2B, a right plate 2C, a left plate 2D, and a rear plate 2E, and is formed in a rectangular parallelepiped shape overall. That is, the enclosure 2 has an upper plate 2A and a lower plate 2B arranged parallel to each other with their plate surfaces facing vertically, a right plate 2C and a left plate 2D arranged parallel to each other with their plate surfaces facing horizontally, and a rear plate 2E arranged with its plate surface facing front to back. Therefore, the right plate 2C, left plate 2D, and rear plate 2E are arranged perpendicular to the upper plate 2A and lower plate 2B and have different orientations. These upper plate 2A, lower plate 2B, right plate 2C, left plate 2D, and rear plate 2E are assembled with screws 10. Here, the front, top, bottom, right, left, and rear of the electronic device 1 are defined with the electronic device 1 mounted in front of the driver's seat of the vehicle. That is, the side facing the driver's seat is the "front," the side facing the windshield at the front of the vehicle is the "rear," and the right and left sides are the directions when viewing the electronic device 1 from the front. The housing 2 is located inside the vehicle cluster (also called the dashboard).

[0013] The display panel 3 is installed on the front side of the housing 2 with its panel surface facing forward. The display panel 3 has a panel frame 3A and a display section 3B that forms the panel surface. The panel frame 3A covers the front side of the housing 2 and is made of synthetic resin. In this embodiment, the panel frame 3A is slightly larger than the housing 2 in the vertical and horizontal directions. The display section 3B is smaller than the panel frame 3A in the vertical and horizontal directions and is housed inside the panel frame 3A in the vertical and horizontal directions. Although not shown in the figure, operation buttons for various operations of the electronic device 1 can be provided on the panel frame 3A in the vertical and horizontal directions. The display section 3B has, for example, a liquid crystal display (LCD) or an organic electro-luminescence (OLED) display. Although not shown in the figure, the display section 3B can be configured as a touch panel.

[0014] As shown in Figures 2 and 3, the electronic device 1 houses a plurality of circuit boards (first components) 6A and 6B inside the housing 2. In this embodiment, two circuit boards 6A and 6B are provided. The circuit boards 6A and 6B are oriented with their surfaces facing vertically and are arranged parallel to the upper plate 2A and the lower plate 2B. In other words, the circuit boards 6A and 6B are arranged perpendicular to the right plate 2C, the left plate 2D, and the rear plate 2E, and have different orientations. As shown in Figure 3, the circuit boards 6A and 6B are provided with connectors 6Ab and 6Bb that mate with each other, and are electrically connected to each other when the connectors 6Ab and 6Bb are mated. In the electronic device 1 of this embodiment, the circuit boards 6A and 6B are positioned by the housing structure of this embodiment so that the connectors 6Ab and 6Bb are securely mated with each other.

[0015] As shown in Figures 2 to 4, the housing structure of the embodiment comprises a reference member 4, a pin member 5, first positioning holes 6Aa and 6Ba provided in the first members, substrates 6A and 6B, second positioning holes 2Ca and 2Da provided in the second members, the right plate 2C and the left plate 2D, and a third positioning hole 2Ba provided in the third member, the bottom plate 2B.

[0016] The reference member 4 is disposed between the substrates 6A and 6B. The reference member 4 is formed of sheet metal and is disposed parallel to the substrates 6A and 6B with the plate surface facing in the vertical direction. The reference member 4 is provided with a plurality of first contact portions 4b (see FIG. 3) formed by cutting and bending the sheet metal along the upper surface of the substrate 6A so as to contact the substrate 6A. The reference member 4 is disposed parallel to the substrate 6A when each first contact portion 4b contacts the upper surface of the substrate 6A. The substrate 6A is fixed to each first contact portion 4b of the reference member 4 via a screw 10. Further, the reference member 4 is provided with a plurality of second contact portions 4c (see FIG. 3) formed by cutting and bending the sheet metal along the lower surface of the substrate 6B so as to contact the substrate 6B. The reference member 4 is disposed parallel to the substrate 6B when each second contact portion 4c contacts the lower surface of the substrate 6B. The substrate 6B is fixed to each second contact portion 4c of the reference member 4 via a screw 10.

[0017] The lower plate 2B is fixed to the reference member 4. The lower plate 2B is provided with first fixing portions 2Bb (see FIG. 3) formed by bending the sheet metal along the lower surface of the substrate 6A so as to contact the substrate 6A in a state where the housing 2 is assembled. A pair of first fixing portions 2Bb are provided so as to face each other in the left - right direction. The lower plate 2B is disposed parallel to the substrate 6A when each first fixing portion 2Bb contacts the lower surface of the substrate 6A. Then, the lower plate 2B is fixed together with each first contact portion 4b of the reference member 4 and the substrate 6A to each first fixing portion 2Bb via a screw 10.

[0018] The right plate 2C and the left plate 2D are fixed to the reference member 4. The reference member 4 is provided with third contact portions 4d (see FIG. 3) formed by bending the sheet metal along the inner surfaces of the right plate 2C and the left plate 2D so as to contact the right plate 2C and the left plate 2D in a state where the housing 2 is assembled. The third contact portions 4d are provided on both the left and right sides of the reference member 4 respectively. The right plate 2C and the left plate 2D are disposed perpendicular to the reference member 4 when the inner surfaces thereof contact the third contact portions 4d of the reference member 4. Then, the right plate 2C and the left plate 2D are fixed to the third contact portions 4d of the reference member 4 via a screw 10.

[0019] Note that the lower plate 2B has the right plate 2C and the left plate 2D fixed thereto. When forming the first fixing portion 2Bb by bending, a second fixing portion 2Bc (see FIG. 3) is formed by bending the sheet metal along the inner surfaces of the right plate 2C and the left plate 2D so as to contact the right plate 2C and the left plate 2D. The second fixing portion 2Bc is provided vertically on both the left and right sides of the lower plate 2B. Then, the right plate 2C and the left plate 2D are fixed to the lower plate 2B via screws 10 in a state of contacting the second fixing portion 2Bc respectively.

[0020] Further, the right plate 2C, the left plate 2D and the lower plate 2B have the rear plate 2E fixed thereto. The right plate 2C has a first fixing portion 2Cc (see FIG. 3) formed by bending the sheet metal along the inner surface of the rear plate 2E so as to contact the rear plate 2E on the upper side of its rear end. The left plate 2D has a first fixing portion 2Dc (see FIG. 3) formed by bending the sheet metal along the inner surface of the rear plate 2E so as to contact the rear plate 2E on the upper side of its rear end. The lower plate 2B has a third fixing portion 2Bd (see FIG. 3) formed by bending the sheet metal along the inner surface of the rear plate 2E so as to contact the rear plate 2E at its rear end. Then, the rear plate 2E is fixed to the right plate 2C, the left plate 2D and the lower plate 2B via screws 10 in a state of contacting the first fixing portion 2Cc, the first fixing portion 2Dc and the third fixing portion 2Bd.

[0021] Further, the right plate 2C and the left plate 2D have the upper plate 2A fixed thereto. The right plate 2C has a second fixing portion 2Cd (see FIG. 3) formed by vertically bending the sheet metal along the inner surface of the upper plate 2A so as to contact the upper plate 2A at its upper end. The left plate 2D has a second fixing portion 2Dd (see FIG. 3) formed by vertically bending the sheet metal along the inner surface of the upper plate 2A so as to contact the upper plate 2A at its upper end. Then, the upper plate 2A is fixed to the right plate 2C and the left plate 2D via screws 10 in a state of contacting the second fixing portion 2Cd and the second fixing portion 2Dd.

[0022] The pin member 5, also called a stud pin, has a fixing portion 5a, a first shaft portion 5b, and a second shaft portion 5c. The pin member 5 is provided on the reference member 4 and is arranged along the vertical direction, which is a predetermined direction, when the housing 2 is assembled. The pin member 5 is configured such that the fixing portion 5a is positioned in the center in the vertical direction, the first shaft portion 5b extends downward from the fixing portion 5a with a uniform diameter, and the second shaft portion 5c extends upward from the fixing portion 5a with a uniform diameter. The fixing portion 5a is fixed to a fixing hole 4a provided in the reference member 4. The fixing portion 5a is inserted through the fixing hole 4a and fixed by crimping. Therefore, the pin member 5 is fixed to the reference member 4, with the first shaft portion 5b extending perpendicularly to the lower plate surface of the reference member 4 below the reference member 4, and the second shaft portion 5c extending perpendicularly to the upper plate surface of the reference member 4 above the reference member 4. These pin members 5 are provided at two locations, on the right end and the left end of the reference member 4.

[0023] The first positioning holes 6Aa are provided at two locations, on the right and left ends of the substrate 6A, respectively. As shown in Figure 4, the first positioning holes 6Aa are provided so that the first shaft portion 5b of the pin member 5 can be inserted through them when the substrate 6A is fixed to the reference member 4. Therefore, the position of the substrate 6A is determined relative to the reference member 4 when the first shaft portion 5b of the pin member 5 provided on the reference member 4 is inserted through the first positioning holes 6Aa.

[0024] The first positioning holes 6Ba are provided through two locations on the right and left ends of the substrate 6B. The first positioning holes 6Ba are provided so that the second shaft portion 5c of the pin member 5 can be inserted when the substrate 6B is fixed to the reference member 4. Therefore, the position of the substrate 6B is determined relative to the reference member 4 when the second shaft portion 5c of the pin member 5 provided on the reference member 4 is inserted through the first positioning holes 6Ba.

[0025] The second positioning hole 2Ca is provided in the center of the right plate 2C, penetrating a positioning piece 2Cb formed by cutting and bending the sheet metal of the right plate 2C inward. The positioning piece 2Cb is provided along the upper plate surface of the reference member 4 when the housing 2 is assembled. The second positioning hole 2Ca is provided so that the second shaft portion 5c of one of the pin members 5 can be inserted through it when assembling the housing 2. Therefore, the position of the right plate 2C is determined relative to the reference member 4 when the second shaft portion 5c of one of the pin members 5 provided on the reference member 4 is inserted through the second positioning hole 2Ca. Note that the number of parts can be reduced by providing the positioning piece 2Cb by cutting and bending the sheet metal of the right plate 2C, but it may also be provided on the right plate 2C by, for example, screws or welding.

[0026] The second positioning hole 2Da is provided in the center of the left plate 2D, penetrating a positioning piece 2Db formed by cutting and bending the sheet metal of the left plate 2D inward. The positioning piece 2Db is provided along the upper plate surface of the reference member 4 when the housing 2 is assembled. The second positioning hole 2Da is provided so that the second shaft portion 5c of the other pin member 5 can be inserted through it when assembling the housing 2. Therefore, the position of the left plate 2D is determined relative to the reference member 4 when the second shaft portion 5c of the other pin member 5 provided on the reference member 4 is inserted through the second positioning hole 2Da. Note that the number of parts can be reduced by providing the positioning piece 2Db by cutting and bending the sheet metal of the left plate 2D, but it may also be provided on the left plate 2D by, for example, screws or welding.

[0027] The third positioning hole 2Ba is provided through the center of the first fixing portion 2Bb of the lower plate 2B in the front-rear direction. The third positioning hole 2Ba is provided so that the first shaft portion 5b of the pin member 5 can be inserted when the lower plate 2B is fixed to the reference member 4. Therefore, the position of the lower plate 2B is determined with respect to the reference member 4 when the first shaft portion 5b of the pin member 5 provided on the reference member 4 is inserted through the third positioning hole 2Ba.

[0028] In the housing structure of this embodiment, the assembly of the housing 2 is performed with reference member 4 as the basis. Specifically, the assembly procedure for the housing 2 is as follows: For the substrate 6A, as shown in Figures 2 and 3, the first shaft portion 5b of the pin member 5 of the reference member 4 is inserted through the first positioning hole 6Aa of the substrate 6A, thereby fixing the substrate 6A to the reference member 4. Also, when fixing the substrate 6A to the reference member 4, the second shaft portion 5c of the pin member 5 of the reference member 4 is also inserted through the third positioning hole 2Ba of the lower plate 2B, thereby fixing the lower plate 2B to the reference member 4 together with the substrate 6B. In this way, the housing structure is positioned with respect to the reference member 4 by the pin member 5, which includes the substrate 6A and the lower plate 2B.

[0029] Next, with respect to the right plate 2C, as shown in Figures 2 to 4, the second shaft portion 5c of the pin member 5 of the reference member 4 is inserted through the second positioning hole 2Ca of the right plate 2C, and the right plate 2C is fixed to the reference member 4. Similarly, with respect to the left plate 2D, the second shaft portion 5c of the pin member 5 of the reference member 4 is inserted through the second positioning hole 2Da of the left plate 2D, and the left plate 2D is fixed to the reference member 4. Note that the order in which the right plate 2C and the left plate 2D are fixed to the reference member 4 may be reversed. In this way, the housing structure is positioned relative to the reference member 4 by the pin members 5, with respect to the right plate 2C and the left plate 2D. After that, the right plate 2C and the left plate 2D are fixed to the lower plate 2B, which is fixed to the reference member 4 together with the substrate 6A, as shown in Figures 2 and 3.

[0030] Next, with respect to the substrate 6B, as shown in Figures 2 and 3, the second shaft portion 5c of the pin member 5 of the reference member 4 is inserted through the first positioning hole 6Ba of the substrate 6B, thereby fixing the substrate 6B to the reference member 4. Furthermore, when fixing the substrate 6B to the reference member 4, the substrates 6A and 6B are positioned on the reference member 4 by the pin member 5, and their connectors 6Ab and 6Bb are fitted together to electrically connect them. In this way, the housing structure has the reference member 4 positioned between the substrates 6A and 6B, and the substrates 6A and 6B are positioned by the pin member 5 provided on this reference member 4.

[0031] Next, the upper plate 2A is fixed to the left plate 2D and the lower plate 2B, as shown in Figures 2 and 3. Since the left plate 2D and the lower plate 2B are positioned and fixed to the reference member 4, the upper plate 2A is fixed without any misalignment relative to the left plate 2D and the lower plate 2B. Similarly, the rear plate 2E is fixed to the right plate 2C, the left plate 2D, and the lower plate 2B, as shown in Figure 3. Since the right plate 2C, the left plate 2D, and the lower plate 2B are positioned and fixed to the reference member 4, the rear plate 2E is fixed without any misalignment relative to the right plate 2C, the left plate 2D, and the lower plate 2B. Note that the order in which the upper plate 2A and the rear plate 2E are fixed may be reversed.

[0032] In the above-described embodiment of the housing structure, an example was given in which the substrates 6A and 6B are positioned and fixed to the housing 2 in the front-rear and left-right directions (horizontal direction), but this is not limited to this. The housing structure may, for example, position and fix the substrates 6A and 6B in the up-down and front-rear directions (vertical direction). In this case, the housing structure may be configured such that, for example, the housing 2 described above has the right plate 2C and the left plate 2D arranged in the up-down direction, and the pin member 5 extends in a predetermined direction, either left-right or front-rear.

[0033] Figures 5 to 8 show other examples of the housing structure of the embodiment. The configurations shown in Figures 5 to 8 differ from the pin member 5 described above mainly in the configuration of the pin members 5', 5''.

[0034] As shown in Figures 5 to 7, the pin member 5' has stepped portions 5d on the first shaft portion 5b and the second shaft portion 5c.

[0035] In the housing structure of the embodiment shown in Figure 5, the stepped portion 5d is provided on the portion where the diameter of the first shaft portion 5b or the second shaft portion 5c is narrowed in the direction extending from the fixed portion 5a. The stepped portion 5d constitutes a locking surface facing downward on the first shaft portion 5b and a locking surface facing upward on the second shaft portion 5c. In the housing structure of the embodiment shown in Figure 5, the pin member 5' is provided with stepped portions 5d on one side so as to lock onto the periphery of the second positioning hole 2Ca of the right plate 2C, the periphery of the first positioning hole 6Ba of the substrate 6B, and the periphery of the first positioning hole 6Aa of the substrate 6A. In addition, in the housing structure of the embodiment shown in Figure 5, the pin member 5' is provided with stepped portions 5d on the other side so as to lock onto the periphery of the second positioning hole 2Da of the left plate 2D, the periphery of the first positioning hole 6Ba of the substrate 6B, and the periphery of the first positioning hole 6Aa of the substrate 6A. Therefore, the housing structure of the embodiment shown in Figure 5 maintains the spacing between members through which the pin member 5' is inserted by the stepped portion 5d, and allows each member to be positioned in the direction in which the pin member 5' extends.

[0036] Furthermore, the housing structure of the embodiment shown in Figure 6 has a configuration in which a substrate 6C is further located above the substrate 6B. In the housing structure of the embodiment shown in Figure 6, the pin member 5' is provided with stepped portions 5d on one side so as to engage with the periphery of the second positioning hole 2Ca of the right plate 2C, the periphery of the first positioning hole 6Ba of the substrate 6B, the periphery of the first positioning hole 6Ca of the substrate 6C, and the periphery of the first positioning hole 6Aa of the substrate 6A. On the other side, the pin member 5' is provided with stepped portions 5d so as to engage with the periphery of the second positioning hole 2Da of the left plate 2D, the periphery of the first positioning hole 6Ba of the substrate 6B, the periphery of the first positioning hole 6Ca of the substrate 6C, and the periphery of the first positioning hole 6Aa of the substrate 6A. Therefore, the housing structure of the embodiment shown in Figure 6 maintains the spacing between members through which the pin member 5' is inserted by the stepped portion 5d, and allows each member to be positioned in the direction in which the pin member 5' extends.

[0037] Furthermore, the housing structure of the embodiment shown in Figure 7 has a configuration in which a substrate 6C is further located above the substrate 6B. Also, the housing structure of the embodiment shown in Figure 7 has a configuration in which some of the stepped portions 5d are provided by spacers 5e. The spacer 5e is formed in a cylindrical shape and is inserted into the second shaft portion 5c between the substrate 6B and the substrate 6C, and has a stepped portion 5d at its upper end that engages with the periphery of the first positioning hole 6Ca of the substrate 6C.Therefore, the housing structure of the embodiment shown in Figure 7 maintains the spacing between members through which the pin member 5' is inserted by the stepped portion 5d, and each member can be positioned in the direction in which the pin member 5' extends.In particular, the housing structure of the embodiment shown in Figure 7 has a stepped portion 5d similar to the housing structure of the embodiment shown in Figure 6, but in the stepped portion 5d that engages with the periphery of the first positioning hole 6Ca of the substrate 6C, the stepped portion 5d can be provided without reducing the diameter of the second shaft portion 5c, thus improving the strength of the second shaft portion 5c.

[0038] As shown in Figure 8, the pin member 5'' is provided only with a second shaft portion 5c that extends upward from the fixing portion 5a with a uniform diameter. The pin member 5'' is fixed by crimping the fixing portion 5a into the fixing hole 2Be formed in the lower plate 2B. The second shaft portion 5c is then passed through a notch 2Bf formed in the first fixing portion 2Bb in the lower plate 2B, replacing the third fixing hole 2Ba described above. The lower plate 2B to which this pin member 5” is fixed is configured as a reference member. Furthermore, the aforementioned reference member 4 is configured as an intermediate member (first member) 4' to which the substrates 6A and 6B are fixed, and the aforementioned fixing hole 4a is configured as the first positioning hole 4e. Therefore, in the housing structure of the embodiment shown in Figure 8, the pin member 5” is positioned with respect to the lower plate 2B, which is the reference member, by having the second shaft portion 5c inserted in the order of the first positioning hole 6Aa of the substrate 6A, the first positioning hole 4e of the intermediate member 4', the second positioning hole 2Ca of the right plate 2C, and the first positioning hole 6Ba of the substrate 6B, in that order. Furthermore, the pin member 5'' has its second shaft portion 5c inserted in the following order: the first positioning hole 6Aa of the substrate 6A, the first positioning hole 4e of the intermediate member 4', the second positioning hole 2Da of the left plate 2D, and the first positioning hole 6Ba of the substrate 6B, thereby positioning each of them with respect to the lower plate 2B, which is the reference member. In the housing structure of the embodiment shown in Figure 8, although not explicitly shown in the figure, the tip (upper end) of the pin member 5'' may be configured to be inserted into a positioning hole formed in the upper plate 2A, thereby positioning the upper plate 2A with respect to the lower plate 2B, which is the reference member.

[0039] Thus, the housing structure of the embodiment comprises reference members 4 and 2B constituting the housing 2, pin members 5, 5', and 5'' fixed to the reference members 4 and 2B and extending in a predetermined direction, first positioning holes 6Aa, 6Ba, and 4e provided in a plurality of first members (substrate 6A, substrate 6B, and intermediate member 4') constituting the housing 2 through which the pin members 5, 5', and 5'' are inserted, and second positioning holes 2Ca and 2Da provided in second members (right plate 2C and left plate 2D) constituting the housing 2, which are arranged in a different orientation from the first members (substrate 6A, substrate 6B, and intermediate member 4') through which the pin members 5, 5', and 5'' are inserted.

[0040] According to the housing structure of this embodiment, the pin members 5, 5', 5” can be used to position multiple first members (substrate 6A, substrate 6B, intermediate member 4') and second members (right plate 2C, left plate 2D) that are positioned in a different orientation from the first members, thereby improving the dimensional accuracy of the housing 2. Moreover, since the housing structure of this embodiment is configured to insert the pin members 5, 5', 5” through the first positioning holes 6Aa, 6Ba, 4e and the second positioning holes 2Ca, 2Da, the positioning configuration is simplified, and the number of steps required during assembly of the housing 2 is reduced, thereby improving ease of assembly. Furthermore, since the pin members 5, 5', 5” are used as supports in the housing structure of this embodiment, the rigidity of the housing 2 can be improved.

[0041] Furthermore, in the housing structure of this embodiment, the pin members 5, 5', and 5'' are arranged at multiple locations relative to the reference members 4 and 2B. Therefore, since the housing structure of this embodiment has multiple pin members 5, 5', and 5'' that act as support columns, the rigidity of the housing 2 can be further improved.

[0042] Furthermore, in the housing structure of the embodiment, the pin members 5', 5'' have stepped portions 5d that engage with the periphery of the first positioning holes 6Aa, 6Ba, 4e and the second positioning holes 2Ca, 2Da. Therefore, in the housing structure of the embodiment, the stepped portions 5d allow the first members (substrates 6A, substrates 6B, intermediate member 4') and the second members (right plate 2C, left plate 2D) to be positioned in the direction in which the pin members 5', 5'' extend.

[0043] Furthermore, in the housing structure of this embodiment, the reference member 4 is positioned between a plurality of first members (substrates 6A and 6B). Therefore, in the housing structure of this embodiment, the pin members 5 and 5' are provided extending in two opposing directions (up and down) relative to the reference member 4, allowing the first members (substrates 6A and 6B) to be positioned in each direction.

[0044] Furthermore, in the housing structure of this embodiment, the reference member is composed of the outer housing member (lower plate 2B). Therefore, by using the outer housing member (lower plate 2B) as the reference member, the housing structure of this embodiment can reduce the number of parts, thereby improving assembly accuracy and simplifying the configuration.

[0045] Furthermore, in the housing structure of this embodiment, the second positioning holes 2Ca and 2Da are provided on positioning pieces 2Cb and 2Db formed by bending a portion of the second member (right plate 2C and left plate 2D).
