A chamfer is applied to the corner in the vertical direction of the surface of the pressing portion 41 opposite to the operation portion 42 (the pressing-side end portion 41A).
(Sealing of sealing fixing part 1)
The sealing procedure of the upper case 110 and the lower case 120 by the sealing fixing part 1 having the above configuration will be described with reference to FIGS. 5 to 8, the connecting string 37 is omitted.
First, as shown in FIG. 5 in plan view of the sealing case portion 2, a case lock 30 is installed in the storage portion 24 of the lower sealing case portion 20. Specifically, the end portions of the two oscillating pieces 31 where the locking pieces 32 are provided are positioned inside the storage portion 24, and the shielding pieces 34 are positioned on the notch portion 25 side. The locking pins 26 are inserted into the pin holes 36 of the moving piece 31 and attached to the back plate 21. At this time, the two oscillating pieces 31 are installed so that the plate surface is inclined with respect to the side surface 22B of the lower sealing case portion 20 so that the contact piece 33 is close and the shielding piece 34 is separated. At this time, the inclination angle of the swing piece 31 is adjusted so that the distance between the end portions 32A of the two locking pieces 32 is shorter than the distance L between the locking plates 25. This is because the upper portion of the case lock 30 protrudes upward from the lower sealing case portion 20, so that when the upper case 110 is slid and mounted, the locking piece 32 is the locking plate of the upper sealing case portion 10. This is to prevent the movement of the upper case 110 from being obstructed by contact with 15. Here, when the case lock 30 is in such a state, the positions of the bases at both ends of the connection string 37 are slightly separated by the rotation of the swing piece 31, so that the connection string 37 becomes linear. That is, the connecting string 37 is formed in a length that allows the shielding piece 34 to be in an open state as shown in FIG. For this reason, as shown in FIG. 4, when the swing piece 31 is in a parallel state, it is bent into a dogleg shape. In FIG. 5, the end of the swing piece 31 abuts against the side plate 22B of the lower sealing case portion 20 so that the swing piece 31 does not rotate any more. Even if not, the connecting string 37 that is linear does not extend any further, so the connecting string 37 rotates the swing piece 31 in a direction in which the locking piece 32 is further away from the locking plates 15 and 25. It also has a function to regulate

  Next, the end portion on the anti-sealing fixing side (left side in FIG. 1) of the overhanging piece 131 of the lower case 120 is fitted into the end portion on the sealing fixing side (right side in FIG. 1) of the guide groove 132 of the upper case 110, The upper case 110 is slid with respect to the lower case 120, the upper case 110 is attached to the lower case 120, and the lower sealing case portion 20 and the upper sealing case portion 10 are joined. As a result, the case lock 30 is housed inside the sealing case part 2, and the opening 3 formed by matching the notch part 23 of the lower sealing case part 20 with the notch part 13 of the upper sealing case part 10 In other words, a part of the shielding piece 34 is projected. Further, the locking plate 25 of the lower sealing case portion 20 and the locking plate 15 of the upper sealing case portion 10 overlap at the same position in the front / rear and left / right directions, and the front sealing case portion 10 is exposed from the back plate 21 of the lower sealing case portion 20. A standing wall extending to the face plate 11 is formed.

Next, the caulking pin 40 is oriented so that the chamfered portion of the pressing portion 41 is in the vertical direction (see FIG. 4), and the two shielding pieces from the distal end side (the side with the chamfered portion) of the pressing portion 41 to the opening 3 are provided. Insert between 34. If it does so, the front-end | tip of the pressing part 41 will contact | abut to the two contact pieces 33 which adjoined mutually and comprised the substantially flush wall surface, and the operation part 42 will be in the state which protruded partially from the opening part 3. FIG.
And the front-end | tip (operation side end part 42A) of the crimping pin 40 which protrudes from the opening part 3 is pushed in inward of a case using the front-end | tip of rod-shaped members, such as a driver. Then, as shown in FIG. 6 (A), the tip of the push-in portion 41 of the caulking pin 40 presses against the abutting piece 33 and moves so as to push away the abutting piece 33. With the center of 26, the locking piece 32 is rotated close to the locking plates 15 and 25 so that the shielding piece 34 moves in the direction of closing the opening 3. At this time, the two shielding pieces 34 are close to each other, but the cutout portion 35 avoids the operation portion 42 of the caulking pin 40 as shown in FIG. The push-in operation of the operation unit 42 is not hindered.

When the operating portion 42 of the caulking pin 40 is further pushed in, the locking piece 32 is hooked on the locking plates 15 and 25 as shown in FIG. In this state, the contact piece 33 is still in contact with the chamfered portion provided at the tip of the pressing portion 41 of the caulking pin 40, and the diameter portion of the pressing portion 41 does not pass between the contact pieces 33. The opposing pieces of the two shielding pieces 34 are close to each other. However, as shown in FIG. 7B, the operation portion 42 of the caulking pin 40 is sandwiched between the notches 35. .
Then, by further pressing the operating portion 42 of the caulking pin 40 from the state shown in FIG. 7, the pressing portion 41 of the caulking pin 40 becomes a side surface opposite to the opening 3 of the sealing case portion 2 as shown in FIG. It moves to 12C, 22C, and the swing piece 31 is in a position parallel to the side plates 12B, 22B of the sealing case portion 2. The contact piece 33 is pushed outward by the pressing portion 41, the surface of the locking piece 32 on the shielding piece 34 side is pressed against the surface of the locking plates 15 and 25 opposite to the opening 3 and the locking piece 32 is The state is locked to the locking plates 15 and 25. Further, the two shielding pieces 34 come into contact with each other in the form of a single plate, and are positioned on the opening 3 side of the end of the operation portion 42 of the caulking pin 40. The operation portion 42 of the caulking pin 40 is located inside (on the side plates 12C and 22C side) the opening 38 formed by the cutout portions 35 of the two shielding pieces 34. Although not shown, the connecting string 37 returns to the original character shape (see FIG. 4).

  In this state, the locking piece 32 prevents the locking plate 15 of the upper sealing case portion 10 from moving in the mounting release direction (left direction in FIG. 8) of the upper case 110 and the lower case 120. Since the moving piece 31 is pivotally fixed to the locking pin 26 in the direction orthogonal to the mounting release direction of the lower sealing case portion 20, the upper sealing case portion 10 moves in the mounting release direction with respect to the lower sealing case portion 20. As a result, the upper case 110 cannot be removed from the lower case 120. If the upper case 110 is forcibly removed, the locking piece 32 is broken, the locking plate 15 is broken, or the locking pin 26 is broken, leaving a trace of destruction. The state of the caulking pin 40 and the case lock 30 can be seen through the surface plate 11 of the transparent upper sealing case part 10, and in such a case, it is possible to perceive illegal sealing release at a glance.

Further, in this state, the operation portion 42 of the caulking pin 40 is visible from the opening 38 of the shielding piece 34 (see FIG. 3), but the distal end surface of the operation portion 42 is located inside the shielding piece 34. Since there is almost no gap between the periphery of the operation portion 42 and the inner periphery of the opening portion 38, the operation portion 42 is pulled out of the opening portion 38 and the caulking pin 40 is Extraction is impossible unless the shielding piece 34 is destroyed.
In order to release the seal, the breakable portion 150 is cut and the entire seal case portion 2 is removed from the substrate case 100.
As described above, according to the substrate case 100 according to the present embodiment, when the caulking pin 40 is pushed in and the case lock 30 locks the sealing case part 2 so that it cannot be removed, the operation part 42 of the caulking pin 40 is connected to the sealing case part 2. Since it is formed so as to be hidden inside and at least cannot be pulled out, unauthorized seal release can be prevented.

In addition, the conventional caulking pin was disposable because it had to be destroyed and removed once it was caulked, but in this embodiment, the caulking pin 40 and the case lock 30 are reused when properly sealed. be able to.
The fitting strength between the locking pin 26 of the lower sealing case portion 20 and the pin hole 36 of the swinging piece 31 for locking the swinging piece 31 of the case lock 30 is determined by the weight of the case lock 30. The case lock 30 is maintained at the position shown in FIG. 5 by setting the swing piece 31 so that it can be rotated by a pressing operation. The substrate case 100 can be assembled as it is (that is, without the case lock 30 dropping or moving) (same in the second embodiment).

In the above-described embodiment, the case lock 30 is formed by integrally forming the two rocking pieces 31 connected by the connecting string 37, but the two rocking pieces 31 formed as separate members are used. Each may be attached to the lower sealing case portion 20.
(Modification 1)
In the above-described embodiment, the cutout portion 35 is provided in the shielding piece 34 of the case lock 30 so that the operation side end portion 42A of the caulking pin 40 can be easily pushed in, but as shown in FIG. The shielding piece 34 does not have to be provided with the notch 35. In this case, when the caulking pin 40 is pushed in as the material of the case lock 30, the shielding piece 34 comes into contact with the operation portion 42 of the caulking pin 40 and curves as shown in FIG. Use one that has enough elasticity. If it has such elasticity, the shielding piece 34 in contact with the rod-shaped member is curved and pushed in by pushing the caulking pin 40 to the innermost end with the tip of the rod-shaped member thinner than the diameter of the operation portion 42. Does not interfere with operation. Then, when the caulking pin 40 is pushed into a fixed position, that is, a position where the locking piece 32 is locked to the locking plates 15 and 25, and the rod-shaped member is pulled out, as shown in FIG. 34 returns to the original plate shape by the restoring force, and closes the opening portion 3 of the sealing case portion 2 to cover the operation portion 42 of the caulking pin 40.

When formed in this way, it becomes more difficult to access the operation portion 42 of the caulking pin 40, and the fraud prevention effect is enhanced.
(Modification 2)
The present invention includes those in which the case lock 30 is not provided with the shielding piece 34. That is, as shown in FIG. 11, the cutout portion 13 of the upper sealing case portion 10 and the cutout portion 23 of the lower sealing case portion 20 are formed in a semicircular shape, and the upper sealing case portion 10 and the lower sealing case portion 20 are joined. The opening 3 that is sometimes formed is formed to have a circular shape having a diameter that is substantially the same as or slightly larger than that of the operation portion 42 of the caulking pin 40. Further, as shown in FIG. 12B, the total length of the caulking pin 40 is substantially the same as the side surfaces 12A and 22A of the sealing case portion 2 when the caulking pin 40 is pushed to the fixed position. It is preferable that the operating portion 42 is within a range where the operating portion 42 is in contact with the inner peripheral surface of the notch 23.

In the case of forming in this way, it is necessary to set the caulking pin 40 to the lower sealing case portion 20 before mounting the upper case 110 to the lower case 120. That is, after assembling the substrate case 100, the push-in portion 41 of the caulking pin 40 cannot be inserted from the opening 3, so that the push-in portion 41 is arranged in advance in the storage portion 24 of the lower sealing case portion 20 and the operation portion 42 is It must be placed in the notch 23 (see FIG. 12A).
When formed in this way, the upper case 110 is attached to the lower case 120 after setting the caulking pin 40, so it takes time to assemble the board case 100, but the structure of the case lock 30 can be simplified, Since only the front end surface of the operation portion 42 of the caulking pin 40 is exposed from the opening 3 of the sealing case portion 2, it is possible to make it difficult to perform an illegal act.

(Modification 3)
As shown in FIG. 13, the present invention includes one in which the contact piece 33 is not provided on the case lock 30. That is, the swing piece 31 and the caulking pin 40 are arranged as shown in FIG. 13A, the upper case 110 is attached to the lower case 120, and the caulking pin 40 is pushed in. Then, as shown in FIG. 13 (B), the caulking pin 40 abuts on the inner side of the rocking piece 31 to spread the rocking piece 31 and the locking piece 32 is locked to the locking plates 15 and 25. . In the illustrated example, the shielding piece 34 is not provided. However, depending on the shape of the opening 3 of the sealing case 2 and the shape and arrangement of the swinging piece 31, the shielding piece 34 may be provided to close the opening 3. May be.

(Modification 4)
In the above-described embodiment, both the upper sealing case portion 10 and the lower sealing case portion 20 are formed in a box shape, but as shown in FIG. 14, the lower sealing case portion 20 is formed in a box shape, The sealing case portion 10 may be formed in a plate shape. In this case, the notch 23 provided in the side plate 22A of the lower sealing case portion 20 becomes the opening 3 of the sealing case portion 2. Further, the locking plate 15 may be provided only on the upper sealing case portion 10. In this case, as shown in the drawing, if the notch 22d through which the locking plate 15 can pass is formed in the side plate 22C of the lower sealing case portion 20, the sliding movement of the upper sealing case portion 10 is not hindered. In this case, although not shown, a closing plate that fits into the notch 22d when joined to the lower sealing case portion 20 may be provided on the lower surface of the upper sealing case portion 10. Alternatively, a locking pin may be provided on the upper sealing case portion 10 to attach the case lock 30, and a locking plate 25 may be provided on the lower sealing case portion 20. In contrast to FIG. 14, the upper sealing case portion 10 may be formed in a box shape, and the lower sealing case portion 20 may be formed in a plate shape. Also in this case, a locking pin for supporting the case lock 30 is provided in either the upper sealing case portion 10 or the lower sealing case portion 20, and a locking plate is provided on the side where the locking pin is not provided. Can do.

Even when formed as described above, the shape of the opening 3, the shape of the case lock 30, and the shape of the caulking pin 40 can be those shown in other modifications.
(Modification 5)
The present invention includes only one swing piece 31 of the case lock 30 as shown in FIG. Further, as shown in the figure, the caulking pin 40 may have a bar shape in which the pushing-side end portion 41A and the operation-side end portion 42A have the same diameter. Although the shielding piece 34 is not provided in the illustrated example, the shielding piece 34 may be provided to close the opening 3 depending on the shape of the opening 3 of the sealing case 2 and the shape and arrangement of the swing piece 31. Good. In the illustrated example, the swing piece 31 may have a shape without the contact piece 33 (see FIG. 13).

Further, although not particularly shown, the shape of the case lock 30 may be provided with three or more rocking pieces 31 in addition to the above. For example, when four oscillating pieces 31 are arranged around the opening 3 of the sealing case portion 2 and the caulking pin 40 is pushed in from the opening 3, the four oscillating pieces 31 open radially and engage with the locking plate. It can be formed to be stopped.
Further, a plurality of swing pieces 31 formed separately are fixed to the upper sealing case portion 10 and the lower sealing case portion 20, respectively, and the swing pieces 31 supported by the upper sealing case portion 10 are locked. The locking piece 32 of the swinging piece 31 supported by the lower sealing case portion 20 is locked to the locking portion formed on the upper sealing case portion 10. You may form so that it may be latched by a part.

As described above, the shape of the case lock 30 and the caulking pin 40 can be various. In short, by pushing the caulking pin 40 into the inside of the sealing case part 2, the swing piece 31 of the case lock 30 rotates and the locking piece 32 is provided in the locking case part 2. It is only necessary to prevent movement of the sealing case portion, which is locked to the portion and the rocking piece 31 is supported and fixed, and the sealing case portion, on which the locking portion is formed, in the mounting release direction.
(Second embodiment)
16 to 18 show a second embodiment of the present invention.
The basic configuration of the substrate case 100 according to the second embodiment is substantially the same as that of the first embodiment. However, in this embodiment, the upper case 110 is covered with the lower case 120 and fixed. It has become.

(Substrate case 100)
As shown in FIG. 16, the substrate case 100 according to the second embodiment includes an upper case 110 and a lower case 120. As shown in FIG. 16 (A), the substrate case 100 joins the upper case 110 and the lower case 120 so that the lower opening of the upper case 110 and the upper opening of the lower case 120 face each other. can do. Alternatively, as shown in FIG. 16B, a bearing 134 is provided at an end opposite to the upper sealing case portion 10 of the upper case 110, and a shaft is provided at the end opposite to the lower sealing case portion 20 of the lower case 120. The upper case 110 may be rotated and joined to the lower case 120 in a state where the portion 133 is provided and the bearing 134 is engaged with the shaft portion 133. The upper case 110 may be provided with a shaft portion, and the lower case 120 may be provided with a bearing. The upper case 110 and the lower case 120 are fixed by engagement of an engaging portion (not shown) and an engaged portion (for example, a locking claw and a locking hole). 16A and 16B, the upper sealing case portion 10 and the lower sealing case portion 20 constitute a sealing case portion 2 that overlaps with each other in the vertical direction.

(Seal fixing part 1)
The seal fixing part 1 in the present embodiment is basically the same as that in the first embodiment. That is, a plurality of upper sealing case portions 10 connected to the upper case 110 via the breakable portion 150 and a plurality of lower sealing case portions 20 connected to the lower case 120 via the breakable portion 150 are provided. When one upper sealing case portion 10 and one lower sealing case portion 20 are combined, one sealing case portion 2 is formed. Further, a caulking pin 40 and a case lock 30 are provided which are disposed in the storage portion 4 which is an internal space of the sealing case portion 2.
And in this Embodiment, as shown in FIG. 17, it forms so that the crimp pin 40 may be pushed in from the surface side of the substrate case 100. As shown in FIG. Specifically, as shown in FIG. 18, which is a cross-sectional view taken along the line EE of FIG. 17, the surface plate 11 of the upper sealing case portion 10 has an opening 17 through which the operation portion 42 of the caulking pin 40 can pass. Is formed. The opening portion 17 of the upper sealing case portion 10 becomes the opening portion 3 of the sealing case portion 2. Further, a locking pin is provided on the side plate 12A (see FIG. 17) opposite to the side plate 12C connected to the upper case 110 and the breakable portion 150 of the upper sealing case unit 10 so as to protrude in the horizontal direction. 16 is provided. Then, the rocking piece 31 of the case lock 30 is supported on the locking pin 16 with the locking piece 32 on the lower side. In FIG. 18, the connecting string 37 between the breakable portion 150 and the case lock 30 is omitted. In the present embodiment, the case lock 30 is not provided with the shielding piece 34. On the other hand, each of the two side plates 12B orthogonal to the side plate 22C connected by the lower case 120 and the breakable portion 150 of the lower sealing case portion 20 is formed with a locking plate 25 protruding toward the inside of the case. Has been.

(Sealing of sealing fixing part 1)
The sealing procedure of the upper case 110 and the lower case 120 by the sealing fixing part 1 having the above configuration will be described with reference to FIG.
In the present embodiment, the sealing operation is performed with the substrate case 100 installed with the lower case 120 on the lower side, the upper case 110 on the upper side, and the substrate surface facing the upper side.
First, the case lock 30 is installed in the storage unit 14 of the upper sealing case unit 10 with the upper case 110 oriented so that the opening is on the upper side (that is, the surface of the upper case 110 is on the lower side). Specifically, the end portions of the two swing pieces 31 where the locking pieces 32 are provided are positioned on the opening side of the upper sealing case portion 10 (the opposite side of the surface plate 11), and each swing piece 31 The locking pins 16 are inserted into the pin holes 36 of the pieces 31 and attached to the side plate 12A. Here, by forming the width dimension of the oscillating piece 31 (the length in the front-rear direction in FIG. 18) shorter than the dimension obtained by subtracting the length of the locking pin 16 from the inner width of the upper sealing case portion 10, The locking pin 16 can be inserted into the pin hole 36 after the oscillating piece 31 is moved toward the side plate 12C and placed in the storage portion 14. When the swing piece 31 is attached to the side plate 12A, the two swing pieces 31 are installed so that the plate surface is inclined with respect to the side plate 12B so that the tips of the contact pieces 33 are close to each other. . At this time, the inclination angle of the swing piece 31 is adjusted so that the distance between the end portions 32A of the two locking pieces 32 is shorter than the distance L between the locking plates 25 of the lower sealing case portion 20. . Note that the fitting strength of the pin hole 36 and the locking pin 16 is set so that the swing piece 31 is not swung by its own weight so that the swing piece 31 is held at the position of FIG. It is desirable to set.

Next, the upper case 110 is oriented so that the opening is on the lower side (that is, the surface of the upper case 110 is on the upper side), and in the storage portion 14 of the upper sealed case portion 10, as shown in FIG. The caulking pin 40 is installed in the state shown. That is, the pressing portion 41 is inserted into the opening 17 from the upper side of the upper sealing case portion 10 to be positioned in the storage portion 14, and the operation portion 42 is protruded from the opening 17. Since the case lock 30 is set first, the press-in portion 41 is supported by the contact piece 33 and the caulking pin 40 does not fall down downward. The fitting strength between the pin hole 36 and the locking pin 16 is preferably set so that the swing piece 31 does not swing due to the weight of the caulking pin 40 and the case lock 30.
Next, the upper case 110 is attached to the lower case 120, and the lower sealing case portion 20 and the upper sealing case portion 10 are joined. As a result, the case lock 30 is completely stored in the sealed case portion 2.

  Next, the operation side end portion 42A of the operation portion 42 of the crimp pin 40 protruding from the opening portion 17 of the upper sealing case portion 10 (the opening portion 3 of the sealing case portion 2) is attached to the tip of a rod-like member such as a screwdriver. Use to push inward in the case. Then, as shown in FIG. 18B, the locking piece 32 rotates so as to move in the direction approaching the locking plate 25. When the operation portion 42 of the caulking pin 40 is further pushed in, as shown in FIG. 18C, the insertion portion 41 of the caulking pin 40 moves to the back plate 21 of the lower sealing case portion 20, and the operation portion 42 of the caulking pin 40 is moved. Is located within a range in contact with the inner peripheral surface of the opening 17 (3). In this state, since the locking piece 32 is located below the locking plate 25, the upper case 110 is prevented from moving in the mounting release direction (upward in FIG. 18), and the swinging piece 31 is fixed to the locking pin 16 in a direction orthogonal to the mounting release direction of the upper sealing case portion 10, so that the upper sealing case portion 10 is moved in the mounting release direction with respect to the lower sealing case portion 20. As a result, the upper case 110 cannot be removed from the lower case 120. If the upper case 110 is forcibly removed, the locking piece 32 is torn, the locking plate 25 is broken, or the locking pin 16 is broken, leaving a trace of destruction. Since the state of the case lock 30 can be visually recognized through the surface plate 11 of the transparent upper sealing case portion 10, in such a case, it is possible to perceive unauthorized release of sealing.

Further, in this state, the operation portion 42 of the caulking pin 40 is visible from the opening portion 17, but the distal end surface of the operation portion 42 is located on the inner side of the surface plate 11, and the periphery of the operation portion 42 and the opening Since there is almost no gap between the inner periphery of the portion 17, it is impossible to pull out the operation portion 42 from the opening portion 17 and extract the caulking pin 40 unless the surface plate 11 is destroyed. In order to release the seal, the breakable portion 150 is cut and the entire seal case portion 2 is removed from the substrate case 100.
The second embodiment having the above configuration has the same effects as the first embodiment.
In the second embodiment, each of the modifications in the first embodiment described above can also be applied. Further, although not particularly illustrated, also in the second embodiment, the caulking pin 40 may be formed so as to be pushed in from the side surface side of the substrate case 100 as in the first embodiment. Also in this case, the locking piece 32 of the case lock 30 is locked by the locking portion provided in the sealing case portion 2 so that the upper sealing case portion 10 is separated from the lower sealing case portion 20 (FIG. 18). It is formed so as not to move in the upward direction. The locking portion where the locking piece 32 is locked is not limited to a plate-like member, and may be a slit or an opening into which the locking piece 32 can be fitted. The swing piece 31 is preferably supported by a locking pin provided in a direction orthogonal to the mounting release direction of the upper sealing case portion 10 and the lower sealing case portion 20.

(Other embodiments)
In the first and second embodiments described above, the case where the upper case 110 and the lower case 120 are sealed using the case lock 30 and the caulking pin 40 has been described, but the sealing structure according to the present invention is described. Can be applied to sealing between the board case 100 and a predetermined fixing base of a gaming machine that fixes the board case 100 (for example, a frame of an internal device such as a back plate of a gaming machine housing or a reel unit). is there. Specifically, although not particularly illustrated, the substrate case 100 is formed so that the back surface of the lower case 120 faces the surface of the fixed base and is mounted on the fixed base, and the substrate case 100 is mounted on the fixed base. A locking plate that is inserted into the inside of the sealing case part 2 is sometimes provided. Then, an opening through which a fixed base locking plate can be introduced is provided on the back surface of the sealing case portion 2. When the substrate case 100 is mounted at an appropriate position on the fixed base, the locking plate is inserted into the storage portion 4 of the sealing case portion 2. After that, by pushing the caulking pin 40 into the sealing case portion 2, the swing piece 31 of the case lock 30 is rotated and the locking piece 32 is locked to the locking plate of the fixed base. As a result, the substrate case 100 is fixed to the fixed base in a non-removable manner.

When formed in this way, the sealing of the substrate case 100 and the fixing base of the substrate case 100 can be performed by the same sealing and fixing part and the same member (case lock 30 and caulking pin 40). For example, in FIG. 1 showing the substrate case 100, in the drawing, two sealing case portions 2 positioned above the fixing portion 140 are used for fixing the case, and two sealing case portions 2 positioned above the fixing portion 140 are used. Can be used for fixing the base.
In addition, each structure of each above-mentioned embodiment and each modification can be used in combination as appropriate within a possible range.
