FIG. 5a shows one of the five pin lid portions 22 arranged in parallel when viewed from above, and FIG. 5b shows a cross section of the pin lid portion 22 taken along the sectional line X1 shown in FIG. In FIG. 5a, a substantially plate-shaped sealing plate 22a is formed so as to be surrounded by a protective wall 22d, and a pair of rectangular through holes 22b1 and 22b2 arranged in the width direction are formed. A notch 22e that is long in the width direction is formed in the back of the through holes 22b1 and 22b2 in the sealing plate 22a. The pin lid portion 22 and the lid main body portion 24 are connected via a thin portion 26 formed to be thin. Since the thin portion 26 is formed to have a small cross-sectional area, it is weaker than other portions and easily breaks. Further, the pin lid portion 22 is connected to the lid portion adjacent in the width direction via the thin portion 26.

  In FIG. 5b, the protective wall 22d is erected substantially perpendicular to the sealing plate 22a. A notch 22e is formed in the wall surface of the protective wall 22d located in the back, and the lowermost end of the wall surface is higher than the sealing plate 22a. A rail insertion portion 24c is formed at the bottom of the thin portion 26 connecting the pin lid portion 22 and the lid body portion 24.

  FIG. 6a shows one of the five pin receiving portions 12 arranged in parallel as viewed from above. 6b, FIG. 7a, and FIG. 7b show cross sections of the pin receiving portion 12 taken along the cross sectional lines X1, X2, and Y1 shown in FIG. In FIG. 6a, the pin receiving part 12 is formed in a substantially box shape, and opens at the upper opening surface 12c. The pin receiving portion 12 is formed with a pair of guide grooves 12b1 and 12b2 surrounded by an inner wall surface of the pin receiving portion 12 in a substantially rectangular shape so that the positions in the depth direction coincide with each other. Accordingly, the portion where the guide grooves 12b1 and 12b2 are formed inside the pin receiving portion 12 is wide. Note that the pin receiving portions 12 adjacent in the width direction are joined to each other.

  In FIG. 6 b, a substantially plate-shaped confirmation portion 12 a that protrudes upward is formed in the back of the pin receiving portion 12. The pin receiving portions 12 are also connected to each other in the confirmation portion 12a. A substantially U-shaped guide rail 14c is formed by projecting a pair of upper and lower substantially plate-shaped portions forward from a wall surface 14b that divides the back of the dish main body portion 14. Furthermore, the wall surface 14b that partitions the back of the dish main body 14 is also a wall that partitions the interior of the pin receiving portion 12 from the front. That is, the wall surface 14b is a common wall surface between the wall surface that divides the back of the dish body portion 14 and the wall surface that divides the interior of the pin receiving portion 12 from the front.

  7a and 7b, the engagement portion 14d is formed by removing a predetermined portion of the common wall surface 14b. An upper stopper 14d1 is formed at the end of the engaging portion 14d on the opening surface 12c side. The upper retaining portion 14d1 is formed in a trapezoidal shape that gradually increases in width from the top to the bottom. On the other hand, the lower portion of the engaging portion 14d is formed with a wide lower retaining portion 14d3, and both ends in the width direction of the lower retaining portion 14d3 reach the side surface of the pin receiving portion 12. A constant width portion 14d2 having a constant width is formed between the upper retaining portion 14d1 and the lower retaining portion 14d3 in the engaging portion 14d. On the other hand, the portion of the common wall surface 14b where the engaging portion 14d is not formed is thinned to form a notch 14e.

  FIG. 8 shows the metal piece 50 as viewed obliquely. In the figure, a substantially plate-shaped protective plate 51 is formed on the upper part of the metal piece 50, and a substantially plate-shaped bottom plate 54 is formed so as to face the protective plate 51 substantially in parallel. A narrow portion 51a is formed in the middle of the protective plate 51 in the depth direction. A side plate 52 that connects the protection plate 51 and the bottom plate 54 is formed to be orthogonal to the protection plate 51 and the bottom plate 54. A pair of substantially plate-shaped pin receiving plates 53 a and 53 b are formed substantially perpendicular to the side plate 52 on the outer side in the width direction in the middle of the side plate 52 in the height direction. Further, the pin receiving plates 53a and 53b face each other in the width direction and are substantially parallel to each other. That is, when viewed from above, the pin receiving plates 53a and 53b and the side plate 52 face each other in a substantially U-shape. Accordingly, the distance between the pin receiving plate 53a and the pin receiving plate 53b facing each other is equal to the width of the side plate 52. Note that the width of the side plate 52 is equal to the width of the constant width portion 14d2 of the engaging portion 14d described above.

  By providing substantially square cutouts at the upper and lower portions of the front free ends of the pin receiving plates 53a and 53b, short engaging ends 53a3 and 53b3 are formed in the vertical direction. Spring pieces 53 a 1, 53 a 2, 53 b 1, 53 b 2 are formed on the outer sides of the pin receiving plates 53 a, 53 b, respectively. The spring pieces 53a1, 53a2, 53b1, and 53b2 are formed by forming two substantially U-shaped cuts in the center of the pin receiving plates 53a and 53b, and the portion surrounded by the cuts is formed outward in the width direction. It is formed by extruding. Since the notch is formed in a substantially U shape, the lower end of the portion surrounded by the notch is farthest from the pin receiving plates 53a and 53b. The spring pieces 53a1, 53a2, 53b1, and 53b2 have spring properties, and repel the external force that pushes inward, trying to restore it outward.

  In the present embodiment, the metal piece 50 is formed by cutting and bending a single metal plate into a predetermined shape. Therefore, the protection plate 51, the side plate 52, the pin receiving plates 53a and 53b, the bottom plate 54, and the spring pieces 53a1, 53a2, 53b1 and 53b2 are formed as an integral member.

  FIG. 9 shows the pin 40 as viewed obliquely. The pin 40 is thicker and more rigid than the metal piece 50. In the figure, a pin 40 is formed in a substantially inverted U shape, so that two substantially rod-shaped tip portions 42a and 42b are formed in the lower portion thereof. Saw blade portions 42a1 and 42a2 are formed at the tip portion 42a, and saw blade portions 42b1 and 42b2 are formed at the tip portion 42b. The saw blade portions 42a1 and 42a2 and the saw blade portions 42b1 and 42b2 face each other inward. The saw blade portions 42a1, 42a2, 42b1, 42b2 are composed of a surface substantially orthogonal to the axial direction of the tip portions 42a, 42b, and an inclined surface that intersects at an acute angle, and the inclined surface is oriented downward. Yes. On the other hand, a substantially plate-like projecting portion 44 is formed on the top of the pin 40, and a substantially plate-like pushing surface 44a is formed by bending the projecting portion 44 substantially perpendicular to the tip portions 42a and 42b. is doing.

  The sealing portion 70a composed of the pin lid portion 22, the pin receiving portion 12, the pin 40, and the metal piece 50 described above can be attached to the pin lid portion 22 by performing a predetermined assembling operation shown in FIGS. It can be fixed relative to the pin receiving portion 12. That is, the lid main body portion 24 integrally molded with the pin lid portion 22 and the dish main body portion 14 integrally molded with the pin receiving portion 12 can be relatively fixed at a position where the control box 70 is closed. .

  FIG. 10 a shows the pin receiving portion 12 with the metal piece 50 mounted inside as viewed from above. 10b, FIG. 11a, and FIG. 11b show cross sections taken along the cross sectional lines X1, X2, and Y2 in the pin receiving portion 12 at this time. The metal piece 50 is attached by being pushed down from the opening surface 12 c into the pin receiving portion 12.

  In FIG. 10 a, the protection plate 51 is located above the pin receiving portion 12 and substantially covers and covers the opening surface 12 c of the pin receiving portion 12. However, the site | part in which the narrow part 51a of the protection board 51 was provided is not covered, but the guide grooves 12b1 and 12b2 in the lower pin receiving part 12 are visible. Further, the guide grooves 12b1 and 12b2 are divided by pin receiving plates 53a and 53b, and a pair of substantially rectangular spaces opened upward are formed on both sides in the width direction. Since the position where the narrow portion 51a of the protection plate 51 is provided and the position where the spring pieces 53a1, 53a2, 53b1, 53b2 are formed coincide with each other, the spring piece 53a2 formed above is formed. 53b2 are visible from above.

  In FIG. 10 b, the bottom plate 54 of the metal piece 50 is inscribed in the bottom surface of the pin receiving portion 12, and the side plate 52 is inscribed in the back surface of the pin receiving portion 12. That is, the bottom plate 54 and the side plate 52 constitute the inscribed plate referred to in the present invention. The protection plate 51 is located above the opening surface 12c of the pin receiving portion 12, and is separated from the opening surface 12c by a predetermined distance. In FIG. 11a, the pin receiving plates 53a and 53b cross the pin receiving portion 12 in the depth direction, and the locking ends 53a3 and 53b3 at the tips thereof reach the common wall surface 14b with the dish main body portion 14, and It is engaged with an engaging portion 14d formed on 14b. The locking ends 53a3 and 53b3 are lowered until they pass through the upper stopper 14d1 in the engaging portion 14d and coincide with the height of the constant width portion 14d2.

  In FIG. 11b, the locking ends 53a3 and 53b3 of the pin receiving plates 53a and 53b on both sides sandwich the constant width portion 14d2 from the outside. Here, when the metal piece 50 is pulled upward from the pin receiving portion 12, the upper portions of the locking ends 53a3 and 53b3 of the pin receiving plates 53a and 53b abut on the substantially trapezoidal upper retaining portion 14d1 from below, I can't pull it out. In order to pull the metal piece 50 upward from the pin receiving portion 12, it is necessary to widen the interval between the locking ends 53a3 and 53b3 of the pin receiving plates 53a and 53b as compared with the upper retaining portion 14d1.

  As described above, the interval between the locking ends 53a3 and 53b3 is defined by the width of the side plate 52. Since the width of the side plate 52 is equal to the constant width portion 14d2, a metal piece is used to increase the interval. 50 needs to be deformed from its original shape. Therefore, it is difficult to pull the metal piece 50 upward from the pin receiving portion 12. On the other hand, if the bottom surface of the pin receiving portion 12 is completely removed and the metal piece 50 is to be pulled downward from the pin receiving portion 12, the lower ends of the locking ends 53a and 52a are connected to the lower locking portion 14d3 of the engaging portion 14d. Interfere with. Since both ends in the width direction of the lower retaining portion 14d3 extend to the side surface of the pin receiving portion 12, even if the interval between the locking ends 53a3 and 53b3 is widened, it cannot be pulled downward from the pin receiving portion 12.

  As described above, it is very difficult to pull the metal piece 50 once mounted up and down from the pin receiving portion 12 unless the engaging portion 14d is destroyed. On the other hand, when the metal piece 50 is attached to the pin receiving portion 12, the lower ends of the locking ends 53a3 and 53b3 of the metal piece 50 entering from the opening surface 12c are prevented from coming out of a substantially trapezoidal shape that is wide downward. It is spread while sliding along the slope of the portion 14d1. Therefore, the metal piece 50 can be mounted while being deformed so as to widen the interval between the locking ends 53a3 and 53b3. In this manner, the pin 40 can be inserted into the pin receiving portion 12 to which the metal piece 50 is mounted.

  FIG. 12 a shows the pin receiving portion 12 when the lid member 20 and the dish member 10 are in the closed position as viewed from above. 12b, FIG. 13a, and FIG. 13b show cross sections taken along the cross sectional lines X1, X2, and Y2 in the pin receiving portion 12 at this time. In FIG. 12 b, the rail insertion portion 24 c of the lid body portion 24 is sandwiched between the guide rails 14 c of the dish body portion 14, and the lid body portion 24 and the dish body portion 14 form a closed control box 70. . At this time, the sealing plate 22a is inserted between the protective plate 51 and the opening surface 12c of the pin receiving portion 12, and the opening surface 12c of the pin receiving portion 12 is closed by the sealing plate 22a. Therefore, except for the through holes 22b1 and 22b2 of the sealing plate 22a and the notch 14e of the common wall surface 14b, the inside of the pin receiving portion 12 becomes a closed space with respect to the outside.

  Further, the common wall surface 14b is cut out at a predetermined portion to form the engaging portion 14d and a notch 14e is formed. However, as shown in FIG. 13b, the rail insertion portion 24c comes into contact with the notch 14e from the front. Is also blocked from the inside. Therefore, the interior of the pin receiving portion 12 is a space that is completely independent from the interior of the closed control box 70. That is, even if the pin receiving part 12 is destroyed, the foreign matter that tries to enter the control box 70 can be blocked.

  On the other hand, the through holes 22b1 and 22b2 formed in the sealing plate 22a in FIGS. 12a and 13a are guide grooves 12b1 and 12b2 of the pin receiving portion 12, the narrow width portion 51a of the protection plate 51, the pin receiving plate 53a, The positions of the spring pieces 53a1, 53a2, 53b1, 53b2 of the 53b are all in the depth direction. That is, a pair of openings for inserting the tip portions 42a and 42b of the pin 40 is formed, and the saw blade portions 42a1, 42a2, 42b1, formed on the tip portions 42a and 42b, are formed below the openings. Spring pieces 53a1, 53a2, 53b1, and 53b2 for biting into 42b2 are respectively positioned.

  FIG. 14 a shows the pin receiving portion 12 with the pin 40 inserted into the pin receiving portion 12 as viewed from above. 14b and 15 show cross sections taken along the cross sectional lines X1 and Y2 of the pin receiving portion 12 at this time, respectively. 14a and 14b, the push-in surface 44a of the pin 40 is substantially parallel to the sealing plate 22a and the protection plate 51, and covers these back portions from above. The outer edge of the pushing surface 44a reaches a position almost in contact with the protective wall 22d, and the entire pushing surface 44a is accommodated in a space surrounded by the protective wall 22d.

  In FIG. 15, the tip portions 42 a and 42 b of the pin 40 penetrate into the inside of the pin receiving portion 12 while traversing the through holes 22 b 1 and 22 b 2 and the narrow width portion 51 a of the protection plate 51. On the other hand, the protruding portion 44 of the pin 40 protrudes outside the protective plate 51. The tip end portions 42a and 42b sandwich the pin receiving plates 53a and 53b from the outside. At this time, the spring pieces 53a1, 53a2, 53b1, and 53b2 projecting outward from the pin receiving plates 53a and 53b respectively bite into the deep portions of the saw blade portions 42a1, 42a2, 42b1, and 42b2.

  When the tip portions 42a, 42b enter from above, the spring pieces 53a2, 53a1, 53b2, 53b1 are acutely angled with respect to the axial direction of the tip portions 42a, 42b of the saw blade portions 42a1, 42a2, 42b1, 42b2. It touches the intersecting slope and is pushed inward to follow this. When the saw blade portions 42a1, 42a2, 42b1, and 42b2 pass, the spring pieces 53a2, 53a1, 53b2, and 53b1 are restored to their original shapes, and bite into the inner portions of the saw blade portions 42a1, 42a2, 42b1, and 42b2. Accordingly, when the pin 40 is to be pulled out thereafter, the lower end portions of the spring pieces 53a2, 53a1, 53b2, 53b1 are surfaces that are substantially perpendicular to the tip portions 42a, 42b of the saw blade portions 42a1, 42a2, 42b1, 42b2. Abut each.

  By doing so, the pin 40 cannot be pulled out unless the pin receiving plates 53a, 53b and the like are broken. In addition, since the pin 40 is thick and has high rigidity, it is difficult to be broken or deformed. When the front end portions 42a and 42b enter from above, the guide grooves 12b1 and 12b2 guide the front end portions 42a and 42b from the outside, and the pin receiving plates 53a and 53b slide in contact with the front end portions 42a and 42b from the inside. Therefore, the pin 40 can be inserted into a predetermined position in a stable state. Further, since the pin 40 is provided with a pushing surface 44a perpendicular to the insertion direction, the pin 40 can be pushed in easily.

  Here, the pin receiving plates 53a and 53b only have to be able to retain and hold the tip portions 42a and 42b, and may have other configurations. For example, instead of the spring pieces 53a2, 53a1, 53b2, and 53b1, rectangular holes may be formed at the locations where the spring pieces 53a2, 53a1, 53b2, and 53b1 are provided. In this case, the saw blade portions 42a1, 42a2, 42b1, 42b2 enter the same rectangular hole from the outside, and with respect to the upper side of the rectangular hole and the tip portions 42a, 42b of the saw blade portions 42a1, 42a2, 42b1, 42b2. The front end portions 42a and 42b can be prevented from coming off due to interference with the substantially vertical surface. Further, when the saw blade portions 42a1, 42a2, 42b1, 42b2 enter the same rectangular hole from the outside, the pin receiving plates 53a, 53b themselves are deformed so as to bend inward, and return to the original shape when they have completely penetrated. To do. In other words, the tip portions 42a and 42b can be retained and retained by utilizing the spring properties of the pin receiving plates 53a and 53b themselves.

  When the pin 40 is inserted in this manner, the pin 40 is pulled out and the pin lid portion 22 and the protection plate 51 cannot move with respect to the pin receiving portion 12. That is, even if the pin lid portion 22 is slid in the depth direction, the pin 40 cannot be slid in the depth direction because the pins 40 interfere with the wall surfaces of the through holes 22b1 and 22b2. On the other hand, even if the pin lid portion 22 is to be moved upward, since the protruding portion 44 of the pin 40 is formed larger than the through holes 22b1 and 22b2, the protruding portion 44 is formed on the sealing plate 22a and the protective plate 51 from above. have a finger in the pie. In particular, in this embodiment, by forming the pin 40 in a substantially U shape, the pin 40 has a single retaining strength that is double that of the single pin 40 and is sandwiched between the through holes 22b1 and 22b2 in the sealing plate 22a. Since the above-mentioned part is held in and fixed, the lid member 20 and the dish member 10 can be fixed more firmly.

  Further, a protective plate 51 is interposed between the sealing plate 22 a and the protruding portion 44. Therefore, even when an excessive load is applied to open the pin lid portion 22 upward, the protective plate 51 protects the load while being distributed over a wide range of the sealing plate 22a, so that the synthetic resin sealing plate is used. The 22a is prevented from being damaged. Further, the protective plate 51 that covers the sealing plate 22 a from above is integrated with the metal piece 50. Therefore, since the protective plate 51 is also held on the pin receiving portion 12 side, the sealing plate 22a can be restrained on the pin receiving portion 12 side also by the protective plate 51.

  When the periphery of the through holes 22b1 and 22b2 in the sealing plate 22a is broken, the pin 40 cannot restrain the pin lid portion 22. For example, it is possible to move the pin lid portion 22 upward by destroying the sealing plate 22a so that the hole diameters of the through holes 22b1 and 22b2 are larger than the protruding portion 44. Further, if the sealing plate 22a is broken so that the through holes 22b1 and 22b2 extend to the back end of the sealing plate 22a, the pin lid portion 22 can slide in the depth direction. However, since the sealing plate 22a is protected from above by the metal protection plate 51, the sealing plate 22a cannot be directly destroyed.

  On the other hand, the pushing surface 44 a is accommodated in a space surrounded by the protective wall 22 d of the pin lid portion 22. Further, as shown in FIG. 14a, since the pushing surface 44a is fitted so that the outer edge thereof is substantially in contact with the protective wall 22d, the projection 44 of the pin 40 on which the pushing surface 44a is formed is tried to be picked with pliers or the like. However, the protective wall 22d obstructs this. Therefore, it is difficult to pick the protruding portion 44 of the pin 40 with pliers or the like, and the pin 40 cannot be forcibly pulled out.

  Here, when the pin receiving plate 53a and the pin receiving plate 53b are deformed so as to approach each other, the amount of the spring pieces 53a1, 53a2, 53b1, and 53b2 bites into the depths of the saw blade portions 42a1, 42a2, 42b1, and 42b2. Decreases and the pin receiving state is weakened. Then, the pin 40 can be pulled upward. However, the locking ends 53a3 and 53b3, which are free ends of the pin receiving plates 53a and 53b, hold the engaging portion 14d inward and cannot approach each other any more. Therefore, the pin receiving state with the pin 40 is also prevented from being weakened.

  Further, the pin receiving plates 53 a and 53 b are accommodated in a space closed by the pin receiving portion 12 and the pin lid portion 22. Therefore, unless the wall surface of the pin receiving plate 12 is destroyed, the pin 40 cannot be removed from the outside by destroying or deforming the pin receiving plates 53a and 53b.

  Moreover, in this embodiment, since the wall surface of the pin receiving plate 12 is protected from the inside by the metal piece 50, it is difficult to destroy the wall surface of the pin receiving plate 12. Specifically, when a foreign object is to enter from the bottom surface side of the pin receiving portion 12, the metal bottom plate 54 prevents this. The bottom plate 54 can also block foreign matter entering from the bottom side to push up the pin 40 from the tip side, and therefore it is impossible to push up the pin 40 from the tip side. Even if it is going to make a foreign material penetrate | invade from the back | inner side surface of the pin receiving part 12, the side plate 52 prevents this.

  Further, even if a foreign object enters from the outside in the width direction to destroy or deform the pin receiving plates 53a and 53b, the tip of the highly rigid pin 40 protects the pin receiving plates 53a and 53b from the outside. The receiving plates 53a and 53b cannot be broken or deformed. Since the protective plate 51, the side plate 52, the pin receiving plates 53a and 53b, and the bottom plate 54 are formed by bending a single metal plate at a substantially right angle, the metal piece 50 as a whole has high rigidity and is free of foreign matter and the like. It is difficult to be deformed by intrusion.

  Furthermore, even if it is going to destroy the sealing plate 22a in order to make a foreign material penetrate | invade from the outer side of the sealing plate 22a, the metal pushing surface 44a prevents this first. Even if the sealing plate 22a is to be destroyed from the gap between the pushing surface 44a and the protection wall 22d, the metal protection plate 51 protects the sealing plate 22a, and thus the sealing plate 22a cannot be destroyed. Further, even if the protective plate 51 is to be removed by turning it up or the like, the protective wall 22d surrounds the protective plate 51 and cannot be removed easily. Therefore, the sealing plate 22a cannot be destroyed. Since the wall surface on the front side of the pin receiving portion 12 is shared with the wall surface 14b of the dish main body portion 14, the common wall surface 14b and the engaging portion 14d formed on the common wall surface 14b cannot be destroyed from the outside. Accordingly, foreign matter or the like can enter the pin receiving portion 12 from any external direction, and the pin receiving plates 53a and 53b cannot be destroyed to remove the pin 40.

  As described above, it has been described that the pin 40 is difficult to be pulled out as an effect of the present invention. However, according to the present invention, it is possible to prevent the metal piece 50 from being pulled out from the pin receiving portion 12. In other words, by first removing the metal piece 50, it is possible to prevent fraud in which the retaining of the pin 40 is released. In particular, the pin receiving portion 12 provided with the metal piece 50 is located below the pin lid portion 22 and is difficult to visually recognize. Therefore, there is a problem that even if the pin receiving portion 12 is broken in order to remove the metal piece 50, it is difficult to find the trace.

  Hereinafter, it will be described that the metal piece 50 is difficult to be extracted from the pin receiving portion 12 as an effect of the present invention. Since the engaging portion 14d with which the metal piece 50 engages is formed on the common wall surface 14b of the control box 70, the engaging portion 14d can be destroyed no matter how much the pin receiving portion 12 extended outside the control box 70 is destroyed. Cannot be destroyed. That is, unless the control box 70 itself is destroyed or the control box 70 is not opened, it is impossible to destroy the engaging portion 14d and extract the metal piece 50. Even if the metal piece 50 can be extracted, the trace of destruction becomes large, so that it is possible to immediately find out that there was an injustice.

  Further, the metal piece 50 is engaged with the pin 40 by the pin receiving plates 53a and 53b, and the protective plate 51 on the sealing plate 22a is fixed to the pin 40 by the narrow width portion 51a. Yes. Accordingly, even if the engaging portion 14d is broken and a hole is made in the bottom surface of the pin receiving portion 12 to forcefully pull the metal piece 50 downward, a considerable force is required. Further, since the protective plate 51 is also removed together, it can be easily recognized that the metal piece 50 has been pulled out from below. Although it is conceivable that only the protective plate 51 is separated from the metal piece 50 and only a portion that cannot be visually recognized is extracted, the protective wall 22d surrounds the protective plate 51, so that it cannot be easily separated. Further, since the pushing surface of the pin 40 protects the upper side of the protective plate 51, it is difficult to separate the protective plate 51.

  Further, as described above, in order to extract the metal piece 50 from the pin receiving portion 12 without destroying the engaging portion 14d, it is necessary to increase the distance between the pin receiving plates 53a and 53b. However, when the pin 40 is inserted as shown in FIG. 15, the pin receiving plates 53 a and 53 b are restrained inward by the pin 40, so that the interval between them cannot be increased. Accordingly, the metal piece 50 is prevented from being extracted from the pin receiving portion 12.

  As described above, in this embodiment, it is very difficult to remove the pin 40 and the metal piece 50 and release the fixation of the lid member 20 and the dish member 10. However, if the sealing portion 70a is uprooted and separated from the control box 70, the sealing portion 70a cannot fix the lid member 20 and the dish member 10 without removing the pins 40 and the metal pieces 50. However, when the plate main body 14 and the pin receiving portion 12 constituting the control box 70 are separated, the metal piece 50 needs to be cut. That is, since the metal piece 50 crosses from the pin receiving part 12 to the engaging part 14d formed on the wall surface 14b of the dish main body part 14, in order to separate the pin receiving part 12 outside the dish main body part 14 without fail. The metal piece 50 must be cut. Therefore, the pin receiving part 12 cannot be easily separated from the dish main body part 14. Of course, it is possible to separate the pin receiving part 12 from the dish member 10 by destroying the entire wall surface of the dish main body part 14, but in this case, a large-scale destruction is required, and the trace becomes conspicuous.

  Further, there are many cases where only the pin receiving portion 12 used (pin 40 is inserted) is tried to be separated so that a small-scale destruction in which an improper trace is not conspicuous is sufficient. In particular, the pin receiving portion 12 is positioned below the lid portion 22 and is difficult to find a trace of destruction, and thus is easily targeted. FIG. 16 shows the sealing portion 70a as seen from an oblique direction. In the same figure, the broken line B1 at the time of trying to isolate | separate only the pin receiving part 12 currently used is shown. In the present embodiment, since the adjacent pin receiving portions 12 are connected to each other, many parts must be cut as indicated by the breaking line B1. Therefore, it is difficult to make the traces inconspicuous while separating only the pin receiving portion 12 being used. Furthermore, since the confirmation part 12a is also connected with the adjacent pin receiving part 12, the breaking line B1 will be formed also in the confirmation part 12a. The break line B1 in the confirmation part 12a extended to the position where it can be visually recognized is easy to visually recognize, and it can be easily recognized that there is a fraud.

  Further, if only the pin receiving portion 12 that is used without breaking the confirmation portion 12a is to be cut off, it must be cut as shown by the breaking line B2, and a great number of portions need to be cut. . As described above, it is very difficult to separate the pin receiving portion 12 being used, and the separated traces are easily noticeable. Therefore, it is very difficult to add a fraud to the control board 25, and it can be easily recognized that the fraud has occurred.

  By the way, when the control board 25 is maintained, it is necessary to open the control box 70 as shown in FIG. In this case, the lid member 20 may be slid strongly toward the front in the depth direction. FIG. 12 shows a breaking line B3 when the lid member 20 is slid strongly toward the front in the depth direction. A thin portion 26 forming a connecting portion between the pin lid portion 22 and the lid main body portion 24 is broken, and a breaking line B3 is formed in the thin portion 26. That is, since the thin portion 26 formed with a small cross-sectional area is easier to break than other portions, only the thin portion 26 is broken. When the thin portion 26 is broken, the pin lid portion 22 is separated from the lid member 20, and thereafter, the lid member 20 can slide in the depth direction. Accordingly, the control board 25 can be maintained.

  Moreover, since the thin part 26 is formed in the position which can be visually recognized from the outside, the fracture | rupture state can be confirmed easily. Therefore, the history of opening the control box 70 can be grasped, and it can be easily known whether there has been an unauthorized opening other than maintenance. Once opened, the pin lid portion 22 connected by the broken thin portion 26 cannot be used again, but the spare pin housed in the adjacent pin lid portion 22 and the spare pin housing box 13 By this, the control box 70 can be closed again. In the state where the control box 70 is closed as shown in FIG. 3, the spare pin storage box 13 is covered with the spare pin lid 23, so that the spare pin is not lost due to mischief or the like.

(4) Second embodiment:
FIG. 17 shows a cross-section of the sealed portion 170a in the sealed state according to the second embodiment. In the figure, the protection plate 151 is bent in a wave shape to cover the outside of the sealing plate 122a. The outer surface of the protection plate 151 is further covered with a pushing surface 144 a of the pin 140. The pin 140 is formed by joining two L-shaped pins having the same shape in sectional view so that the back faces face each other. Therefore, the pushing surface 144a is formed toward the front and the back. The outer edge of the pushing surface 144a reaches the protective wall 122d. That is, the pushing surface 144a covers the sealing plate 122a and the protection plate 151 surrounded by the protective wall 122d without any gap. Other configurations are the same as those in the first embodiment.

  With this configuration, the rigidity of the protection plate 151 is improved, and the inside of the sealing plate 122a and the pin receiving portion 121 can be more securely protected. Further, since the pushing surface 144a further covers the outer side of the protective plate 151, a double protective structure is provided, and the inside of the sealing plate 122a and the pin receiving portion 121 can be more firmly protected. Further, since the gap between the pushing surface 144a and the protective wall 122d is formed small, the pushing surface 144a cannot be picked with pliers or the like. Accordingly, it is very difficult to pull out the pin 140.

  FIG. 18 shows the sealing portion 170a according to the second embodiment as viewed from an oblique direction. In the figure, the surface of the confirmation portion 112a formed by extending the pin receiving portion 112 is colored black, and the inside and other portions are transparent. By doing in this way, the fracture | rupture condition of the confirmation part 112a can be confirmed clearly. That is, the transparent interior of the confirmation portion 112a is exposed at the fracture surface (for example, the fracture line B11). Accordingly, the contrast between the surface of the confirmation portion 112a colored in black and the transparent interior is increased, and it can be easily recognized that the surface has been broken. In the present embodiment, since the inside and other parts are formed transparently, by irradiating light from the back side, the contrast can be increased and the breaking condition can be confirmed more reliably.

(5) Third embodiment:
FIG. 19 shows a cross-section of the sealed portion 270a in the sealed state according to the third embodiment. In the figure, the protective plate 251 is folded back and overlapped with two. A groove 222d1 is formed outward at a portion of the front protective wall 222d perpendicular to the sealing plate 222a, and the tip of the protective plate 251 enters the groove 222d1. Other configurations are the same as those in the first embodiment. By doing in this way, the intensity | strength of the protection board 251 improves and it becomes possible to protect the inside of the sealing board 222a and the pin receiving part 221 more firmly. Further, since the groove 222d1 restrains the tip portion of the protective plate 251, the protective plate 251 is prevented from being turned up.

(6) Fourth embodiment:
FIG. 20 shows the metal fitting 350 according to the fourth embodiment as viewed from above. In the figure, the metal plate 350 is provided with a protective plate 351 as in the first embodiment, and a pair of substantially Y-shaped cuts 351b1351b2 are formed on the protective plate 351 from the outside in the width direction. A plurality of circular visual holes 351e are formed in the protective plate 351 in a grid pattern. FIG. 17 shows a cross-section of the sealed portion 370a in the sealed state according to the fourth embodiment. In the drawing, the portion of the protective plate 351 where the substantially Y-shaped cut 351b1 is formed is located above the through hole 322b1 formed in the sealing plate 322a, and the tip 342a of the pin 340 is the through hole. When inserted into the 322b1, it is bent along the wall surface of the through hole 322b1 so as to avoid this. Other configurations are the same as those in the first embodiment.

  With this configuration, the wall surface of the through hole 322b1 can be protected by the metal protection plate 351. Accordingly, it is possible to effectively prevent the destructive action of expanding the hole diameter of the through hole 322b1 in order to enable relative movement between the lid member 320 and the dish member 310. In addition, since it is not necessary to bend the protective plate 351 along the wall surface of the through hole 322b1 in advance, the processing is simple. Furthermore, by forming the visual recognition hole 351e, it is possible to visually recognize the internal state of the pin receiving portion 12 from above.

(7) Summary:
As described above, in the gaming machine according to the present invention, the lid member and the dish member are relatively fixed and the control box is sealed by inserting the pin that pinches the lid member and the dish member constituting the control box. Let Then, by covering the periphery of the through hole into which the pin is inserted with a metal protective plate from the outside, the periphery of the through hole where the pin restraining force is exerted is prevented from being broken from the outside. Since the protection plate is formed by extending the pin receiving plate that holds the tip end portion of the pin in a retaining state to the outside, the outer side is removed when the pin receiving plate is removed to release the retaining state of the pin tip portion. The protective plate is also removed. Therefore, the trace from which the pin receiving plate is removed can be easily confirmed from the outside.
