Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine having a high anti-fraud effect.

  In a gaming machine such as a pachinko machine, a bulleted game ball is a game area (an area formed on or near the game board surface and an area for realizing a game or an effect by the flow of the game ball). In the process of flowing down, the game ball rolls while colliding with game nails and windmills in the game area, and the flow direction changes. As a result, if a game ball wins at various winning holes arranged on the game area, a predetermined winning ball is paid out. On the other hand, if a game ball flows into the out port without winning any of the winning holes, the winning ball Will not be paid out. The player enjoys the game by demonstrating his / her skill in the ball or using the chance of the game ball flowing down and expecting the game ball to be won and paid out.

  In such pachinko machines, game modes and effects have become more complex and diversified year by year, and the structure and functions of electronic circuit boards for controlling the operation and effects of game machines have become more complex and diversified accordingly. Have been doing. If such an electronic board is illegally destroyed or modified, there is a risk that the game will not be played properly or that some illegal players will be given an unfair advantage. . For this reason, the electronic substrate is enclosed by the substrate case and is difficult to access from the outside.

  By including the electronic substrate in the substrate case in this manner, unauthorized access to the electronic substrate can be made difficult. In general, a substrate case that encloses an electronic board is composed of a main body case and a lid case. The lid case is made of a transparent material so that the mounting surface of the enclosing electronic circuit board can be seen through. Yes.

  The main body case and the lid case are sealed so as not to be opened (separated) by a sealing member called a caulking member. The caulking member is installed irreversibly (that is, not removable) so as to straddle the main body case and the lid case. Once the main body case and the lid case are sealed with the caulking member, thereafter, both cases cannot be opened unless the caulking member is destroyed or the substrate case is destroyed. Therefore, if both cases are opened and fraudulent acts are performed on the electronic board, even if the electronic board is returned to its original position, traces of destruction remain on the caulking member and the board case. The history of being released can be found.

  For example, Patent Document 1 discloses a structure in which the main body 2 and the lid 3 are sealed with a lock pin 16. Further, in Patent Document 2, the sealing engaging portion 46 of the sealing pin 37 is engaged with the pin locking portion 35 of the first case body 14, and the first case body 14, the second case body 16, A configuration in which is sealed is disclosed.

  However, in recent years, unauthorized opening of the substrate case has been performed more skillfully. For example, a hole such as a drill is drilled in the board case, a tool such as a wire is inserted through the hole to release the engagement between the caulking member and the board case, and the caulking member is pulled out from the board case. Unauthorized opening of cases may occur. However, in principle, it is preferable that the caulking member is not pulled out of the substrate case even if the substrate case is illegally made.

  The present invention has been made in view of the above circumstances, and provides a board case unit and a gaming machine that make it difficult to cheat on a sealing member and can effectively prevent cheating on a board case. This is an exemplary problem.

  In order to solve the above problems, a substrate case unit as an exemplary aspect of the present invention includes a first case, a second case, a first case, a first case, and a first case that together form an electronic substrate. And a sealing member that seals the two cases in a substantially non-separable manner, wherein the first case is provided with a through-hole that allows the sealing member to pass therethrough. An insertion hole for inserting the sealing member is disposed on the side, and the sealing member is formed so as to protrude from the substantially cylindrical main body portion that passes through the through hole and is inserted into the insertion hole, and on the upper side of the main body portion. A flange portion and an expansion portion that can be expanded laterally from the main body portion, the flange portion engages in the vicinity of the inlet of the through hole, and the expansion portion is formed inside the insertion hole. The first case and the second case are sealed by engaging with the mating recess. The extension portion has a plurality of extension pieces that extend from the main body portion to the side, and when the main body portion is inserted into the insertion hole, the plurality of extension pieces expand in the radial direction. This engages with the engaging recess.

  The expansion part has a plurality of expansion pieces, and when the main body part is inserted into the insertion hole, it expands in the radial direction and engages with the engaging recess, so that it expands at multiple locations around the main body part. The piece and the engaging recess are engaged. Therefore, even if the engagement of the extension piece at one location is released, the remaining extension pieces are engaged, so that it is very difficult to remove the sealing member from the substrate case.

  For example, when trying to release the engagement by improperly making a hole in the board case and pushing the extension piece, in order to remove the sealing member, a hole is made at a plurality of locations all around the main body part at the same time. Therefore, it is necessary to push in the extension piece, and the illegal act can be substantially disabled. Therefore, it is possible to effectively prevent the act of illegally removing the sealing member and illegally opening (separating) the substrate case, thereby preventing unauthorized modification or replacement of the electronic substrate in the substrate case. .

  Here, typically, the sealing member is made of metal, and the main body has a cylindrical shape. Of course, there is no problem even if the main body has a shape other than the columnar shape, for example, a square shape or a hexagonal column shape. The flange portion is a disc portion having a larger diameter than the main body portion, and is a portion that engages with the first case. The expansion piece that expands from the main body portion to the side may be, for example, a protrusion piece that protrudes to the side (that is, a direction orthogonal to the longitudinal direction of the main body portion), and has elasticity. It may be a resin piece that bends toward the side, or a leaf spring piece that is formed of a metal material such as spring steel and bends toward the side. The phrase “a plurality of extending pieces expand in the radial direction” means that the above-described protruding pieces, resin pieces, leaf spring pieces, and the like protrude from the main body in the radial direction, that is, in different directions.

  The expansion part is configured as a separate body from the main body part, has a substantially cylindrical shape, and a part of the side surface of the cylinder is separated along the longitudinal direction so that the inner diameter can be expanded and contracted. The main body portion can be inserted, and a plurality of expansion pieces that are expanded independently by elastic deformation by a plurality of slits formed in the cylindrical side surface along the longitudinal direction may be configured.

  Since the extension portion is configured as a separate body from the main body portion, the main body portion side of the sealing member can be formed with a simple structure and shape. And, since the diameter of the separate expanded portion can be expanded and contracted, the insertion work is easy even when the main body portion is inserted into the hollow interior, and the diameter of the main body portion varies somewhat. Also fits properly.

  Since the extension piece is formed by forming a plurality of slits in the main body portion, the formation of the extension piece is very simple. Moreover, if the expansion part has elasticity by resin or spring steel, the diameter when the sealing member is passed through the through hole is reduced, and the expansion part is elastically deformed, for example, in a petal shape within the insertion hole. The expansion of the diameter can be repeatedly performed without plastic deformation or damage.

  On the peripheral surface of the main body part, a small diameter part having a small diameter through a step and a large diameter part having a larger diameter than the small diameter part are formed on both sides of the small diameter part. The dimension is greater than or equal to the longitudinal dimension of the extension, and the step size between the large diameter part and the small diameter part is greater than or equal to the thickness dimension of the extension on the cylindrical side surface. The rotation of the extension part relative to the main body part may be restricted by meshing.

  Since the extension portion is stored in the small diameter portion of the main body portion, the main body portion to which the extension portion is attached can be smoothly passed through the through hole formed in accordance with the large diameter portion. And after passing through a through-hole, an expansion piece expands in an insertion hole, and a reliable sealing is realized. In addition, if it has a rotation restricting structure in which a part of the large diameter part and a part of the extension part mesh, the extension part may rotate around the central axis carelessly with respect to the main body part. Is prevented.

  A gaming machine according to another exemplary aspect of the present invention includes a gaming machine body that implements a game using gaming media, a gaming machine frame that holds the gaming machine body, the board case unit, and the board case unit. And an electronic substrate included in the package.

  According to this gaming machine, unauthorized opening of the board case is prevented, and unauthorized access to the electronic board in the board case is prevented. The possibility that the game machine hall side will suffer unexpected disadvantages will be reduced. Therefore, it can contribute to providing a safe and reliable game. Here, the gaming machine is typically a pachinko machine, but of course, various gaming machines using an electronic board, such as a pachislot machine, a slot machine, an arcade game machine, and the like can be considered.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, unauthorized opening of a substrate case can be prevented more effectively than before with a simple configuration, and access to the electronic substrate in the substrate case, such as unauthorized modification and replacement, can be prevented. Therefore, it prevents illegal profits of the player and unexpected disadvantages on the hall side, and contributes to safe and secure game provision.

The lid case 35b rotates relative to the main body case 35a, thereby opening the opening of the main control board case 35. An open state and a closed state are realized.

<Structure of sealing member>
A sealing portion 41 is formed on the upper portion of the main control board case 35. The sealing portion 41 is configured by attaching a sealing member 44 to a through hole 42 formed in the main body case 35a and an insertion hole 43 formed in the lid case 35b (see also FIG. 6). The substrate case unit 45 is configured to include the sealing member 44, the main body case 35a, and the lid case 35b.

  FIG. 5 is an exploded view of the sealing member 44. The sealing member 44 has a main body portion 44a and a flange portion 44b, and is configured by attaching an extension portion 46 that is a separate body to the main body portion 44a. The main body portion 44a and the flange portion 44b are integrally formed in the first embodiment. The main body 44a and the flange 44b are metal members having a substantially cylindrical shape. A flange portion 44b having a larger diameter than the main body portion is formed on the upper portion of the main body portion 44a.

  A small-diameter portion 47 having a small diameter through a step is formed in the main body 44a, and a large-diameter portion 48 having a larger diameter than the small-diameter portion is formed through a step on both sides of the small-diameter portion. ing. The main body portion 44 a is inserted into the hollow portion of the expansion portion 46, and the expansion portion 46 is attached so as to be wound around the small diameter portion 47.

  The extended portion 46 is formed of spring steel in the first embodiment, but may be formed of resin. It has a substantially cylindrical shape, and a part of the side surface of the cylinder is a separation part 46a separated along the longitudinal direction. By the existence of the separation part 46a, the inner diameter of the expansion part 46 can be expanded and contracted. Yes. Therefore, the main body portion 44 a is inserted while slightly expanding the separation portion 46 a, and after the insertion, the inner diameter is reduced by the spring property of the expansion portion 46, and the expansion portion 46 is in close contact with the small diameter portion 47.

  FIG. 6 is a cross-sectional view of the sealing member 44 in a state where the expansion portion 46 is attached to the main body portion 44a. The expansion portion 46 is attached so that the expansion piece 49 opens (expands) toward the flange portion 44b. The longitudinal dimension H1 of the small diameter part 47 is set to be equal to or greater than the height dimension (longitudinal dimension) H2 of the expansion part 46. Therefore, the extended portion 46 does not reach the large diameter portion 48 and is accommodated in the small diameter portion 47 in the longitudinal direction. The step dimension D1 between the large diameter part 48 and the small diameter part 47 is not less than the thickness dimension D2 of the expansion part 46. Therefore, in a state where the expansion piece 49 is closed (two-dot chain line in FIG. 6), the external dimensions of the main body 44 a including the thickness of the expansion 46 are not more than the dimensions of the large diameter portion 48. Since the through-hole 42 has such a size that the large-diameter portion 48 can be inserted, the through-hole 42 can pass through the through-hole 42 of the expansion piece 49 attached to the small-diameter portion 47.

  A plurality of expansion pieces 49 are formed so as to be elastically deformed independently by a plurality of slits 52 formed along the longitudinal direction (height direction) on the cylindrical side surface of the expansion portion 46. The slit 52 is formed up to an intermediate position (substantially the center) in the height direction of the extended portion 46, and a plurality of extended pieces 49 are cut and raised from the portion in the radial direction. The expansion piece 49 substantially exhibits a sealing function in a plurality of radial directions.

  Further, a protruding portion 48a protruding in the longitudinal direction is formed on a part of the large diameter portion 48, and is a notched portion that is a part of the extended portion 46 and is partially cut out at a position corresponding to the protruding portion 48a. 46b is formed. The notch 46b and the protrusion 48a mesh with each other, whereby the rotation of the extension 46 with respect to the main body 44a is restricted. Therefore, the extended portion 46, that is, the extended piece 49, does not rotate unintentionally with respect to the main body portion 44a.

<Installation procedure of sealing member>
When the main body case 35 a and the lid case 35 b are closed, the insertion holes 43 are arranged corresponding to the through holes 42. The main body 44 a of the sealing member 44 is passed through the through hole 42. As the main body 44 a passes, the expansion piece 49 comes into contact with the inlet of the through hole 42. When the main body 44 a is pushed in, the expansion piece 49 closes (shrinks) due to its elasticity and passes through the through hole 42.

  In a state where the expansion piece 49 is closed, the expansion portion 46 moves from the through hole 42 to the insertion hole 43 together with the main body portion 44a. An engagement groove (engagement recess) 43 a is formed inside the insertion hole 43. The engagement groove 43 a is a groove having a diameter larger than the diameter of the through hole 42 and formed along the inner wall peripheral surface of the insertion hole 43, and allows expansion of the expansion piece 49 in the radial direction.

  When the expansion part 46 passes through the through hole 42 and reaches the engagement groove 43a inside the insertion hole 43, the expansion piece 49 is elastically deformed in a petal shape inside the engagement groove 43a based on the elasticity and expands radially. As a result, the upper end portion 49a of the extension piece 49 is engaged with the upper surface 43b in the engagement groove 43a, and the main control board case 35 is sealed. Since the plurality of expansion pieces 49 expand in various directions (radial directions) and engage with the upper surface 43b of the engagement groove 43a, all of the plurality of expansion pieces 49 are simultaneously moved in the reduction direction. It is substantially impossible to remove the sealing member 44.

[Modification]
FIG. 7 is an external perspective view of a sealing member 44 according to a modification of the present invention. The sealing member 44 has a main body portion 44a and a flange portion 44b, and a protruding pin 50 that can be advanced and retracted in four directions from the main body portion 44a is provided in a protruding manner. The protruding pin 50 protrudes radially from the inside of the main body 44a by a biasing member such as a spring, and can be retracted into the main body 44a by pressing it from the outside.

  A tapered surface 51 is formed on the lower side of the protruding pin 50. The tapered surface 51 receives the entrance portion of the through hole 42 obliquely, so that the protruding pin 50 is naturally retracted into the main body portion 44a as the main body portion 44a is inserted into the through hole 42. When the protruding pin 50 reaches the engaging groove 43a inside the insertion hole 43, it protrudes in the radial direction, and the engagement between the sealing member 44 and the lid case 35b is realized.

The main control substrate case 66 includes a main body case (first case) 66a and a lid case (second case) 66b. have. In the pachinko machine 62 according to the second embodiment, a lid case 66b is mounted on the back surface of the game board, and the main body case 66a is attached to the lid case 66b from the rear side of the gaming machine.

  In the second embodiment, the main control board 34 is fastened to the lid case 66b with screws. Then, the main control board 34 is placed so as to cover the main body case 66a with respect to the lid case 66b from the rear while being shifted in the right direction (the right direction indicated by the direction arrow in FIGS. 8 and 9 and the right direction in the pachinko machine 62). Storing. Thereafter, when the main body case 66a is slid leftward, the engagement hook 67 of the lid case 66b engages with the engagement hole 68 of the main body case 66a, and both cases 66a and 66b are closed.

  After the sliding movement, the sealing member 71 is inserted into the through hole 42 formed in the body case 66a and the insertion hole 70 disposed on the lid case 66b side. FIG. 10 is an exploded view of the sealing member 71. FIG. 11 is a cross-sectional view showing a state where the sealing member 71 is attached to the main control board case 66 shown in FIG.

<Structure of sealing member>
A sealing portion 74 is formed on the upper portion of the main control board case 66. The sealing portion 74 has a through hole 42 formed in the main body case 66a, a receiving hole 75 formed in the lid case 66b, and a receiving member (engaging member) 76 inserted into the receiving hole 75. A sealing member 71 is attached to the insertion hole 70 of the receiving member 76 from 42. The substrate case unit 65 is configured to include the sealing member 71, the main body case 66a, and the lid case 66b.

  The sealing member 71 includes a main body portion 72 and a flange portion 78, and an extension portion 73 that is a separate body is attached to the main body portion 72. The main body portion 72 and the flange portion 78 are integrally formed in the second embodiment.

  The main body 72 and the flange 78 have a generally cylindrical shape and are preferably made of a metal member such as iron or brass, and have high resistance to breakage and deformation due to their high strength. Therefore, it is difficult to illegally destroy or process the main body 72. A flange portion 78 having a larger diameter than the main body portion 72 is formed on the upper side of the main body portion 72 (arrow X side in FIG. 10). The flange portion 78 is inserted into and engaged with the through hole 42 of the main body case 66a.

  A small-diameter portion 72a having a small diameter through a step is formed on the lower side (−X direction) side of the main body portion 72, and a circumferential groove recessed in the circumferential direction on the peripheral surface 72b of the small-diameter portion. 72c is formed. A bent portion 73a on the extended portion 73 side described later is engaged with the circumferential groove 72c.

  The extension 73 is formed of spring steel in the second embodiment, but may be formed of resin. In the expanded state, the extended portion 73 has six extended pieces 73c extending in a radial direction from a bottom portion 73b that is a substantially hexagonal flat plate, and has a generally snow crystal-like shape. The six extended pieces 73c are cut and raised at an angle of about 60 ° to 85 °, and the distal ends of two to three extended pieces 73c among the six extended pieces 73c are bent inward to form bent portions 73a.

  When the extended portion 73 is inserted from the lower side of the main body portion 72 with the bottom portion 73b as a lower side, the bent portion 73a is expanded along the tapered portion 72e formed on the lower side of the main body portion 72 and is engaged with the circumferential groove 72c. It is supposed to be. Accordingly, the inserted extension part 73 cannot be removed from the main body part 72.

  For example, the diameter φ1 = 16 mm of the flange portion 78, the diameter φ2 = 10 mm of the large diameter portion 72d of the main body portion, the diameter φ3 = 9 mm of the small diameter portion 72a, and the diameter φ4 = 6 mm of the circumferential groove. At this time, for example, the length L1 of the extension piece 73c (without the bent portion 73a) L1 = 5.5 mm, and the diameter of the virtual circle formed by the distal ends of the plurality of extension pieces 73c (without the bent portion 73a) φ5 = 13 mm, the length L2 of the extension piece 73c (with the bent portion 73a) L2 = 5.0 mm, and the diameter of the virtual circle formed by the bent portion 73a is φ6 = 6.5 mm.

  Since φ4 <φ6 <φ3, the bent portion 73a is reliably engaged with the circumferential groove 72c, and the extended portion 73 is rotatable with respect to the main body portion 72 in this state. Further, when the expansion piece 73c is folded along the main body 72 in the engaged state, the expansion piece 73c can be accommodated in the small diameter portion 72a. That is, the tip of the extension piece 73c does not reach the step portion between the small diameter portion 72a and the large diameter portion 72d, and the thickness of the extension piece 73c is equal to or less than the radial difference between the large diameter portion 72d and the small diameter portion 72a. Has been.

  Since the extended portion 73 is formed of spring steel, it has elasticity. In the engaged state of the main body portion 72 and the expansion portion 73, the expansion width of the expansion piece 73c expands in the radial direction from the lower side (−X side) toward the upper side (X side). When the sealing member 71 is inserted into the through hole 42, the expansion piece 73c is folded along the main body 72 due to its elasticity, and is accommodated in the small diameter portion 72a. After the insertion is completed, the expansion piece 73c expands radially in the insertion hole 70 due to its elasticity.

  A receiving member 76 is inserted into the receiving hole 75 of the lid case 66b. In the second embodiment, the receiving member 76 is a separate member from the lid case 66b, and it is impossible or difficult to remove from the lid case 66b by the pressing member 79. As means for realizing the installation with respect to the lid case 66b, an engagement means or a fastening means (not shown) may be used.

  The receiving member 76 is formed with an insertion hole 70. The insertion hole 70 is a hole into which the expansion piece 73c is engaged when the sealing member 71 is inserted. As shown in FIG. 11, the insertion hole 70 has a small diameter portion 70a and a large diameter portion (engagement recess) 70b. The small diameter portion 70 a is disposed in the vicinity of the entrance of the insertion hole 70 and has substantially the same diameter as the through hole 42. The small diameter portion 70a allows passage of the main body portion 72 of the sealing member 71 and the expanded portion 73 folded, but prevents passage of the expanded piece 73c in the expanded state.

  The large diameter portion 70b is disposed on the back side following the small diameter portion 70a and has a larger diameter than the small diameter portion 70a. The expanded piece 73c in the folded state that has passed through the small diameter portion 70a is allowed to expand at the large diameter portion 70b. The distal end portion 73d of the expanded piece 73c in the expanded state is in a larger diameter state than the small diameter portion 70a. Therefore, even if the sealing member 71 is to be pulled out, the distal end portion 73d cannot contact the upper surface 70c and pass through the small diameter portion 70a, and the sealing member 71 cannot be pulled out. As a result of the expansion of the expansion piece 73c, the sealing member 71 seals the main body case 66a and the lid case 66b with the flange portion 78 and the expansion piece 73c in an unopenable manner.

  In the insertion hole 70, for example, φ2 <diameter φ7 of the small diameter portion 70a = diameter of the through hole 42 = 11 mm <φ3, φ7 <diameter φ8 of the large diameter portion 70b = 15 mm.

<Installation procedure of sealing member>
Since the mounting procedure of the sealing member 71 is substantially the same as that of the first embodiment, detailed description thereof is omitted. That is, the main body case 66a and the lid case 66b are closed, and the sealing member 71 is inserted into the through hole 42 from the bottom 73b side. When the insertion is completed, the expansion piece 73c expands in the radial direction within the large-diameter portion 70b of the insertion hole 70 and enters an expanded state. In this expanded state, the sealing member 71 seals the main body case 66a and the lid case 66b so that they cannot be opened, so that the main control board 34 housed inside cannot be illegally accessed.

[Embodiment 3]
The third embodiment will be described with reference to FIGS. In addition, about the structure similar to Embodiment 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The sealing member 81 is inserted into the through hole 42 formed in the body case 66a and the insertion hole 70 disposed on the lid case 66b side. FIG. 12 is an exploded view of the sealing member 81. FIG. 13 is a cross-sectional view showing a state in which the sealing member 81 is attached to the main control board case 66.

<Structure of sealing member>
A substrate case unit 77 is configured to include a sealing member 81, a main body case 66a, and a lid case 66b.

  The basic structure of the sealing member 81 is similar to the structure of the sealing member 71 in the second embodiment. As a different point from the sealing member 71 in Embodiment 2, the sealing member 81 can list the point which has the protrusion pin 82, the accommodating part 83, and the crimping | crimped part 84. FIG. Further, the main body portion 81a does not have a small diameter portion corresponding to the small diameter portion 70a in the second embodiment.

  The protruding pin 82 protrudes from the main body portion 81a so as to be able to advance and retract in the lateral direction (radial direction). It is urged toward the projecting direction (side, radial direction) by an urging member (not shown) such as a spring, and when it is pushed from the side toward the cylindrical central axis of the main body 81a, it enters the main body 81a. Evacuation is possible.

  The accommodating part 83 is for accommodating the expansion piece 73c. In the third embodiment, the accommodating portion 83 is four vertical grooves that are recessed along the cylindrical central axis direction on the peripheral surface 85 of the main body portion 81a. The expansion part 73 in Embodiment 3 has four expansion pieces 73c. The four expansion pieces 73c do not have a bent portion.

  The four accommodating portions 83 are arranged at positions corresponding to the four expansion pieces 73c. When the expansion pieces 73c are folded along the main body portion 81a in a state where the expansion portions 73 are attached to the main body portion 81a, the four accommodating portions 83 are expanded. The piece 73 c is accommodated in the accommodating portion 83. Therefore, when the sealing member 81 is inserted into the through hole 42 of the main body case 66a, the main body portion 81a and the extension piece 73c can pass through the through hole 42 having the same diameter as that of the main body portion 81a.

  An oval-shaped caulking hole 73e is opened at the bottom 73b of the extended portion 73, and a caulking convex portion 72f is formed to project from the lower side of the main body portion 81a. The caulking portion 84 is configured to include the caulking holes 73e and the caulking convex portions 73f.

  The caulking convex portion 72f is formed to project at a position corresponding to the caulking hole 73e. The outer shape of the caulking convex portion 72f is an oval shape corresponding to the caulking hole 73e. By inserting the caulking convex portion 72f into the caulking hole 73e and caulking them together, the main body portion 81a and the expansion portion 73 are coupled with high strength. Moreover, since the crimping hole 73e and the crimping convex part 72f are oval-shaped, the positioning of the extension part 73 with respect to the main body part 81a is facilitated. As a result, accurate positioning of the extension piece 73c with respect to the accommodating portion 83 is facilitated.

  The receiving member 76 in the third embodiment is substantially the same as the receiving member 76 in the second embodiment. When the sealing member 81 is inserted into the insertion hole 70 of the receiving member 76 through the through hole 42 on the main body case 66a side while the protruding pin 82 is retracted in the main body portion 81a, the expansion piece 73c is housed in the housing portion 83 while being accommodated in the housing portion 83. The portion 81a passes through the through hole 42. When the insertion is completed, the expansion piece 73c expands in the radial direction within the large diameter portion 70b of the insertion hole 70. Further, the protruding pin 82 protrudes laterally within the large diameter portion 70b. Thereby, the main body case 66a and the lid case 66b are sealed by the sealing member 81 so as not to be opened.

  Here, as shown in FIG. 13, when the sealing member 81 is pulled in the pulling direction (X direction), the position P where the protruding pin 82 engages with the upper surface 70c of the large diameter portion 70b is If not, the extension piece 73c is positioned closer to the flange portion 78 than the position (that is, the distal end portion 73d) to be engaged with the upper surface 70c.

  That is, in the engaged state between the protruding pin 82 and the upper surface 70c, the extension piece 73c and the upper surface 70c are configured not to engage with each other. Therefore, when an external force in the pulling direction is applied to the sealing member 81, the pulling is first firmly prevented by the engagement between the protruding pin 82 and the upper surface 70c.

  In the unlikely event that the projecting pin 82 is damaged or malfunctioned and cannot be engaged with the upper surface 70c, or when the engagement between the projecting pin 82 and the upper surface 70c is canceled by an illegal act, This time, the four expansion pieces 73c are engaged with the upper surface 70c, thereby preventing the sealing member 81 from being pulled out. Since the engagement functions doubly and the second engagement prevents the main control board case 66 from being opened even if one engagement is released, unauthorized access to the main control board 34 is further strengthened. To be prevented.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary.

  For example, in the sealing member 71 of the second embodiment, the bent portion 73 a of the extension portion 73 is engaged with the circumferential groove 72 c of the main body portion 72, and the extension portion 73 rotates in the circumferential direction with respect to the main body portion 72. It is possible.

  However, for example, as shown in Modification 2 in FIG. 14, a caulking hole 73 e is opened in the bottom 73 b of the extension portion 73, and a caulking convex portion 72 f is formed to protrude at a corresponding position on the lower side of the main body 72. The caulking protrusion 72f may be inserted into the hole 73e and then both may be caulked. In addition to the engagement between the circumferential groove 72c and the bent portion 73a, the caulking hole 73e and the caulking convex portion 72f are caulked, so that the coupling between the main body 72 and the extended portion 73 is further enhanced. Even if the bent portion 73a may fall off the circumferential groove 72c, separation of both is prevented by caulking.

  In addition, due to the caulking connection between the main body portion 72 and the expansion portion 73, the expansion portion 73 can be made non-rotatable in the circumferential direction with respect to the main body portion 72.
