Description

  The present invention relates to a gaming machine board case in which a housing space for housing a control board is formed by combining a case body and a lid member.

  Conventionally, various measures have been taken on this type of substrate case from the viewpoint of preventing illegal acts on the control substrate accommodated therein. Specifically, for example, as described in Patent Document 1, a cylindrical member is provided in each of a case main body and a lid member assembled to the case main body, and solid pins are inserted into these cylindrical members. A substrate case is known in which a relative displacement between the main body and the lid member (displacement in the direction in which the substrate case is opened) is prevented to prevent an illegal act on the accommodated control board.

  By the way, the case main body and the lid member constituting the substrate case as described above are formed of a transparent synthetic resin material such as polycarbonate (PC) so that an illegal act on the accommodated control board can be easily confirmed from the outside. It is common.

  Then, the cylindrical member provided in each of the case main body and the lid member is the same synthetic resin material as the case main body and the lid member, and it is formed integrally with the case main body and the lid member, thereby improving the production efficiency. It is desirable from the viewpoint of

  However, if the cylindrical member is formed of a synthetic resin material, there is a risk that a dimensional error will occur during molding.

  In addition, depending on the ambient temperature of the substrate case, the cross section in the direction perpendicular to the axis of the cylindrical member provided on each of the case main body and the lid member may be deformed.

  As a result, it becomes difficult to insert the solid pin into the cylindrical member provided in each of the case main body and the lid member, and it may be difficult to obtain the press-fitted state of the solid pin into at least one cylindrical member. The cylindrical member may be damaged by forcibly inserting the solid pin, or the solid pin can be inserted into both cylindrical members, but the inserted solid pin may easily come off. The solid pin that has been press-fitted into at least one of the two cylindrical members may be easily removed from the pressed-in cylindrical member due to a change in the ambient temperature of the substrate case. There is a problem that it is difficult to advantageously obtain a stable sealed state.

JP 2005-342193 A

  Here, the present invention has been made in the background as described above, and the problem to be solved is a substrate for a gaming machine having a novel structure capable of realizing a stable sealing state. To provide a case.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  The present invention is for housing a control board, and in a board case for a gaming machine in which a lid member is assembled to a case body, the lid member is assembled to the case body. The internal space of the main body side cylindrical portion integrally formed on the outer peripheral edge of the main body and the lid side cylindrical portion integrally formed at a position corresponding to the main body side cylindrical portion of the case main body at the outer peripheral edge of the lid member While positioning so that it is connected, a spring pin inserted across the main body side cylinder part and the lid side cylinder part is fitted to at least one of the main body side cylinder part and the lid side cylinder part, and the case main body And the lid member are fixed.

  In the gaming machine substrate case having such a structure according to the present invention, the main body side cylinder positioned so that the respective internal spaces are connected in a state where the lid member is assembled to the case main body. The case main body and the lid member are fixed by fitting a spring pin inserted between the main body side cylindrical portion and the lid side cylindrical portion with the spring pin inserted across the portion and the lid side cylindrical portion. Yes.

  Then, in a state where the spring pin is fitted to at least one of the main body side cylinder portion and the lid side cylinder portion, an external force inward in the direction perpendicular to the axis with respect to the spring pin, that is, in the direction of tightening the spring pin The external force is exerted to deform the cross-sectional shape of the spring pin in the direction perpendicular to the axis. As a result, a force (restoring force) for returning to the original shape of the spring pin is exerted on the cylindrical portion on which the spring pin is fitted, and the outer peripheral surface of the spring pin and the cylindrical portion on which the spring pin is fitted. It is possible to advantageously secure the frictional force generated between the two. That is, in the present invention, the frictional force generated between the outer peripheral surface of the spring pin and the cylindrical portion on which the spring pin is fitted is advantageously utilized by utilizing the spring action in the direction perpendicular to the axis of the spring pin itself. It is possible to secure it. As a result, even if there is a dimensional error at the time of molding in the main body side cylinder part or the lid side cylinder part or the ambient temperature of the board case for gaming machines has changed, the displacement in the axial direction of the spring pin, It is possible to advantageously prevent displacement of the spring pin in the direction in which it is removed from the cylinder portion, and stabilization of the state where the spring pin is fitted to at least one of the main body side cylinder portion and the lid side cylinder portion. Can be achieved.

  Therefore, in the board case for gaming machines of the present invention, a stable sealed state can be advantageously realized.

  In the present invention, the material for forming the case main body and the lid member is not particularly limited, but is preferably formed of a transparent synthetic resin material such as polycarbonate (PC). Thereby, it becomes possible to visually recognize the control board accommodated in the board case for gaming machines from the outside.

  In the present invention, the number of the main body side cylinder part and the lid side cylinder part may be one or plural, respectively. Furthermore, in the present invention, “the state in which the internal spaces of the main body side cylinder portion and the lid side cylinder portion are connected” means that the spring pin can be inserted across the main body side cylinder portion and the lid side cylinder portion. Say something. In that case, the main body side cylinder part and the lid side cylinder part may be overlapped, or may be spaced apart with an appropriate gap.

  Furthermore, in the present invention, the cross-sectional shape in the axis-perpendicular direction of the main body side cylinder part and the lid side cylinder part is not particularly limited, for example, a circle, an ellipse, a polygon, or a distortion thereof. Various cross-sectional shapes such as a shape can be adopted, but it is desirable to correspond to the cross-sectional outer shape in the direction perpendicular to the axis of the spring pin. Thereby, it is possible to advantageously ensure a contact area between the outer peripheral surface of the spring pin and the inner peripheral surface of the cylindrical portion. As a result, it is possible to advantageously secure the frictional force generated between the outer peripheral surface of the spring pin and the inner peripheral surface of the cylindrical portion on which the spring pin is fitted, and the axial displacement of the spring pin is advantageous. Can be prevented.

  Furthermore, in the present invention, the size and shape of the cross section in the direction perpendicular to the axis of the main body side cylinder part and the lid side cylinder part do not need to be constant in the axial direction of the cylinder part, for example, one end side in the axial direction And the other end may have different cross-sectional sizes and shapes.

  Further, the spring pin in the present invention is not particularly limited as long as it has a shape that generates a spring action in a direction perpendicular to the axis. For example, the spring pin extends over the entire length in the axial direction in a part of the circumferential direction of the spring pin. The shape in which the notch is formed, the peripheral wall is a cylindrical shape that is continuous in the circumferential direction, the cross-sectional shape in the direction perpendicular to the axis is a polygon that has a roundness at each apex, and A cross-sectional shape in the direction perpendicular to the axis is spiral, and a shape in which at least a part of the peripheral wall overlaps in the direction perpendicular to the axis is adopted. Therefore, when a cut is formed over the entire length in the axial direction in a part of the circumferential direction of the spring pin, the cut does not need to extend straight along the axial direction of the spring pin, For example, it may extend in a direction inclined with respect to the axial direction, or may extend so as to meander.

  Furthermore, in the present invention, the outer shape of the cross section in the direction perpendicular to the axis of the spring pin is not particularly limited as long as it has a shape that causes a spring action in the direction perpendicular to the axis of the spring pin. A substantially oval shape, a substantially polygonal shape, or a distorted shape thereof is employed.

  Furthermore, in the present invention, the thickness dimension of the peripheral wall of the spring pin may be constant in the circumferential direction or may be different. Therefore, in the case of a spring pin in which a cut is formed over the entire length in the axial direction in a part of the circumferential direction, the thickness dimension of the peripheral wall is the largest at the portion facing the cut in the direction perpendicular to the axis. On the other hand, it is desirable that the thickness dimension is gradually reduced from the portion to the cut along the circumferential direction. Thereby, the stress which generate | occur | produces in a cylinder part in the state by which the spring pin was fitted by the cylinder part is made uniform in the circumferential direction. As a result, it is possible to bring the outer peripheral surface of the spring pin into close contact with the inner peripheral surface of the cylindrical portion over the entire circumference in a state in which the spring pin is fitted to the cylindrical portion. Can be more advantageously prevented.

  Furthermore, in the present invention, the spring pin has a shape in which a cut is formed over the entire length in the axial direction in a part of the circumferential direction, and the cross-sectional shape in the direction perpendicular to the axis of the circumferential wall is spiral. When the shape is such that at least a part of the peripheral wall overlaps in the direction perpendicular to the axis, for example, by a method of forming a notch over the entire length of the tube in the axial direction, a method of rounding a plate material, etc. A spring pin is advantageously formed. Further, in the present invention, when the spring pin is a shape in which the peripheral wall is continuous in the circumferential direction and the cross-sectional shape in the direction perpendicular to the axis is a polygon having roundness at each apex, for example, The desired spring pin is advantageously formed by drawing or extruding.

  In the present invention, the material for forming the spring pin is not particularly limited as long as it can advantageously obtain a spring action in a direction perpendicular to the axis. For example, steel, spring steel, and stainless steel for springs are used. Etc. can be adopted.

  Further, in the present invention, an insertion protrusion that protrudes from the center portion of the plate-shaped piece to one side in the plate thickness direction is inserted and fixed to one end side of the spring pin, and the end portion on which the insertion protrusion is inserted and fixed is A spring pin is inserted across the main body side cylinder part and the lid side cylinder part from the opposite end, and the spring pin is fitted to at least one of the main body side cylinder part and the lid side cylinder part, With the lid member fixed, the plate-shaped piece is locked to the opposite side of the spring pin insertion direction with respect to either the main body side cylinder part or the lid side cylinder part located on the spring pin insertion side. It is desirable to do so. As a result, the displacement in the direction opposite to the direction in which the spring pin is inserted causes the plate-like piece to be locked to either the main body side cylinder part or the lid side cylinder part located on the spring pin insertion side. This will prevent you. As a result, it is possible to further stabilize the state in which the spring pin is fitted to at least one of the main body side cylinder part and the lid side cylinder part, and the sealing state of the board case for gaming machines is further advantageous. It can be realized.

  Therefore, in the present invention, the locked state in which the plate-like piece is locked to either the main body side cylinder part or the lid side cylinder part located on the spring pin insertion side is the inner peripheral surface of the cylinder part. The locking piece may be realized by being locked to the step formed, or the locking piece is fitted into an opening hole formed in the cylinder portion in the direction perpendicular to the axis, It may be realized by locking a locking piece on the inner peripheral surface of the opening hole.

Thereby, each main body side cylinder part 28 is integrally formed with respect to the surrounding wall 20 as an outer peripheral edge part of the case main body 12.

  Therefore, in the present embodiment, the opening direction (direction in which the central axis extends) of each main body side cylinder portion 28 is relative to the opening direction of the opening portion 22 of the case main body 12 (direction substantially orthogonal to the bottom plate 18). It is almost parallel.

  In the present embodiment, a lower housing portion 32 that extends in the opening direction (axial direction) of the main body side cylinder portion 28 in a U-shaped cross section is integrally formed above each main body side cylinder portion 28. The lower housing portion 32 and the main body side tubular portion 28 are communicated with each other through a communication hole formed in the bottom wall of the lower housing portion 32.

  Furthermore, in the present embodiment, an upper stage accommodating part 34 that extends in the opening direction (axial direction) of the main body side cylinder part 28 with a U-shaped cross section is integrally formed above each lower stage accommodating part 32. And the upper stage accommodating part 34 and the lower stage accommodating part 32 are connected by the notch formed in the bottom wall of the upper stage accommodating part 34. As shown in FIG. In the present embodiment, the two adjacent upper storage portions 34 share a side wall portion (side wall portion extending in the width direction of the case body 12) located in the adjacent direction.

  The lid member 14 to be assembled to the case body 12 having such a structure is formed of a transparent hard synthetic resin material such as polycarbonate (PC) like the case body 12, and is shown in FIGS. As shown in the figure, as a whole, a peripheral wall 37 extending along the outer peripheral edge of the top plate 36 is erected, and an opening that opens downward is formed. In addition, the top plate 36 of the present embodiment is provided with an inclined portion in an intermediate portion in the width direction (vertical direction in FIG. 5), whereby the distance from the top plate 36 to the opening end at both ends in the width direction. Are different.

  A plurality (eight in the present embodiment) of lid-side cylinders 38 are integrally formed on one side wall portion of the lid member 14 in the width direction. In particular, in the present embodiment, four of these eight lid-side cylindrical portions 38 are collectively provided on one side and the other side in the longitudinal direction across the center in the longitudinal direction of the lid member 14.

  Therefore, in this embodiment, each lid-side cylinder portion 38 is a cylinder that extends straight with a substantially constant cross section with respect to the bottom wall of the upper housing portion 40 having a frame shape or a cylindrical shape opening with a rectangular cross section. The lower housing portion 42 is shaped so as to protrude downward in the axial direction on the same central axis, and the upper housing portion 40 and the lower housing portion 42 are formed on the bottom wall of the upper housing portion 40. They are communicated with each other through the formed communication holes.

  In particular, in this embodiment, the opening direction (direction in which the central axis extends) of each lid side cylinder portion 38, that is, the opening direction (direction in which the central axis extends) of the upper housing portion 40 and the lower housing portion 42 is the lid member. 14 opening directions (directions substantially perpendicular to the top plate 36).

  In the lid-side cylinder portion 38 having such a structure, the upper housing portion 40 is attached to one side wall portion in the width direction of the lid member 14 by a pair of attachment pieces 44 and 44. Thereby, each lid side cylinder part 38 is integrally formed with respect to the peripheral wall 37 as an outer peripheral edge part of the lid member 14.

  Next, a method for assembling the lid member 14 having the above-described structure to the case body 12 will be described. First, a pair of longitudinally facing wall portions 46, 46 that are opposed to each other in the longitudinal direction of the lid member 14 (the left-right direction in FIG. 5) are a pair of guide grooves 26, 26 formed at both longitudinal ends of the case body 12. Fit in. At that time, as shown in FIG. 8, the locking pieces 48, 48 provided in the respective guide grooves 26 in the case body 12 are engaged with the longitudinally facing wall portions 46 in the lid member 14. It is designed to be accommodated in the stop cutouts 50, 50. Note that the locking pieces 48 of the present embodiment are provided integrally with the side wall portion of each guide groove 26, respectively.

  Therefore, in the present embodiment, as described above, the pair of longitudinally facing walls 46 and 46 in the lid member 14 are fitted in the pair of guide grooves 26 and 26 in the case body 12, and The top plate 36 of the bottom plate 18 and the lid member 14 is substantially parallel except for the inclined portion of the top plate 36.

  Although not clearly shown in the drawings, in the present embodiment, as described above, the longitudinally opposed walls 46 and 46 of the lid member 14 are fitted into the guide grooves 26 and 26 provided in the case body 12. Before, the control board 16 is screwed to the lid member 14 in a state where the connector 52 mounted thereon protrudes outside from a window 54 formed in the lid member 14. The control board 16 is a control board to be inspected by a predetermined inspection organization (specifically, for example, a main control board that controls the overall operation of the gaming machine or a control signal from the main control board). The payout control board for controlling the payout of the award medium based on the above.

  The direction in which the locking pieces 48 are locked to the locking notches 50, 50 from such a state (the direction in which the opening 22 of the case body 12 is covered with the lid member 14, that is, the direction in which the lid is closed). As shown in FIG. 9, the lid member 14 is slidably displaced with respect to the case main body 12 (in this embodiment, the slidable displacement is to move the top plate 36 in parallel with the bottom plate 18). The locking pieces 48 and 48 are locked to the locking notches 50 and 50. As a result, the lid member 14 is assembled to the case body 12, and the opening 22 of the case body 12 is covered with the lid member 14 as shown in FIG. As a result, the control board 16 screwed to the lid member 14 is put into the case body 12 through the opening 22.

  In the present embodiment, as described above, in the state where the opening 22 of the case body 12 is covered with the lid member 14, as shown in FIG. The formed protrusion 56 is adapted to be fitted into an insertion hole 58 formed in the other side wall portion in the width direction of the lid member 14.

  Further, as described above, by sliding and displacing the lid member 14 with respect to the case main body 12, as shown in FIG. 10, the lower accommodating portion 42 in the lid-side cylindrical portion 38 is formed on the main body-side cylindrical portion 28. The upper housing portion 40 of the lid side cylinder portion 38 is positioned in the upper housing portion 34 formed above the lower housing portion 32, while being positioned in the lower housing portion 32 provided above. Yes. Thereby, the lid side cylinder part 38 and the main body side cylinder part 28 are positioned on the same central axis in a state where the lid member 14 is assembled to the case main body 12. That is, the lid side cylinder part 38 is provided at a position corresponding to the main body side cylinder part 28 in the lid member 14. Then, as described above, the lid side cylinder part 38 and the main body side cylinder part 28 are positioned on the same central axis, so that the internal space 39 of the lid side cylinder part 38 and the internal space 27 of the main body side cylinder part 28 are described later. It will be in the position which permits insertion of the spring pin 60 to perform. As is clear from this, in the present embodiment, the lid side cylinder portion 38 and the main body side cylinder portion 28 are positioned on the same central axis in a state where the lid member 14 is assembled to the case main body 12. Thus, the internal space 39 of the lid side cylinder part 38 and the internal space 27 of the main body side cylinder part 28 are connected. In the present embodiment, as described above, with the lid side cylinder portion 38 and the main body side cylinder portion 28 positioned on the same central axis, the lower end surface of the lower accommodation portion 42 in the lid side cylinder portion 38 A gap is formed between the upper surface of the lower housing part 32 formed integrally with the main body side cylinder part 28.

  In the present embodiment, the lid member 14 is slid relative to the case body 12 so that the top plate 36 moves in parallel with the bottom plate 18, so that the lid member 14 moves relative to the case body 12. Since the lid member 14 is assembled to the case main body 12, the direction in which the lid-side cylindrical portion 38 and the main-body-side cylindrical portion 28 are arranged (the lid-side cylindrical portion 38 and the main body are arranged). The direction in which the central axis common to the side tube portion 28 extends) is substantially orthogonal to the sliding direction of the lid member 14 relative to the case body 12.

  As described above, the spring pin 60 is fitted into the main body side cylinder portion 28 and the lid side cylinder portion 38 that are positioned on the same central axis. Therefore, the spring pin 60 of the present embodiment is formed of steel, spring steel, spring stainless steel, or the like, and as shown in FIG. 11 and FIG. It has a cylindrical shape in which a cut 62 extending while meandering is formed. Note that such a spring pin 60 is advantageously formed by, for example, rounding a plate material in which both ends in the longitudinal direction are formed in a sawtooth shape using an appropriate machine or tool. In addition, the spring pin 60 of the present embodiment is chamfered over the entire circumference with respect to the outer corners at both ends in the axial direction, so that from either side of both ends in the axial direction. Also, the spring pin 60 is advantageously inserted into the main body side cylinder portion 28 and the lid side cylinder portion 38.

  In the present embodiment, the assembly pin 64 is attached to such a spring pin 60. This assembly pin 64 is formed of a synthetic resin material such as ABS, and as shown in FIGS. 13 and 14, the thickness is from the central portion of the plate-like piece 66 that is a rectangular flat plate as a whole. An insertion shaft 68 as an insertion protrusion protruding on one side in the direction is integrally formed. In the present embodiment, chamfering is applied to the lower corners at both ends in the longitudinal direction of the plate-like piece 66 over the entire length in the width direction of the plate-like piece 66. Thereby, it becomes possible to move advantageously from the upper side opening in the upper side accommodating part 40 of the plate-shaped piece 66 mentioned later to a bottom wall.

  As shown in FIG. 15, the assembly pin 64 having such a structure has the insertion shaft 68 inserted and fixed from one axial end of the spring pin 60, whereby the spring pin 60. It is assembled against. Although not explicitly shown in the drawings, in this embodiment, the assembly pin 64 is assembled to the spring pin 60 in this manner in the axial direction above the spring pin 60 (the assembly pin 64 is When viewed from the assembled side), the spring pin 60 is covered by the plate-like piece 66 of the assembly pin 64.

  As described above, the spring pin 60 to which the assembly pin 64 is assembled is, as shown in FIG. 16, from the other end side in the axial direction to which the assembly pin 64 is not attached to the lid side cylinder portion. 38 to be inserted.

  Thereby, the force which fastens the spring pin 60 will act with respect to the part currently inserted by the lower side accommodating part 42 in the spring pin 60. FIG. As a result, the force (restoring force) that the spring pin 60 tries to return to the original shape acts on the lower housing portion 42.

  Then, when the restoring force by the spring pin 60 as described above acts on the lower housing portion 42, the outer peripheral surface of the spring pin 60 is pressed against the inner peripheral surface of the lower housing portion 42. As a result, a frictional force is generated between the outer peripheral surface of the spring pin 60 and the inner peripheral surface of the lower housing portion 42 in a direction that prevents the spring pin 60 from being displaced.

  Then, as described above, when the spring pin 60 is further inserted against the frictional force from the state in which the spring pin 60 is inserted into the lower housing portion 42, as shown in FIG. Is inserted across the lid side cylinder portion 38 and the main body side cylinder portion 28.

  Therefore, in the present embodiment, as described above, the spring pin 60 is inserted into the lower accommodating portion 42 of the spring pin 60 in a state where the spring pin 60 is inserted across the lid side cylindrical portion 38 and the main body side cylindrical portion 28. A force for tightening the spring pin 60 is applied only to the portion that is present. That is, in this embodiment, the frictional force that prevents the axial displacement of the spring pin 60 is applied only to the portion of the spring pin 60 that is fitted in the lower housing portion 42. As a result, in the present embodiment, the spring pin 60 is fitted only to the lid-side cylinder part 38 (lower accommodation part 42).

  In the present embodiment, as described above, the spring pin 60 is inserted across the lid side cylinder portion 38 and the main body side cylinder portion 28, and the spring pin 60 is fitted and fixed to the lid side cylinder portion 38. In this state, one end of the spring pin 60 in the axial direction is positioned in the lid side cylindrical portion 38 and the other end of the spring pin 60 in the axial direction is positioned in the main body side cylindrical portion 28. It has been.

  Although not explicitly shown in the drawings, in the present embodiment, any one of the combinations of the main body side cylinder portion 28 and the lid side cylinder portion 38 that are grouped into four groups is shown in FIG. As shown in FIG. 5, the spring pin 60 is inserted across the main body side cylinder portion 28 and the lid side cylinder portion 38.

  Furthermore, in this embodiment, when the spring pin 60 is further fitted from the state shown in FIG. 16, both longitudinal ends of the plate-like pieces 66 of the assembly pin 64 fixed to the spring pin 60 are the upper side. It is made to slide with respect to a pair of opposing wall parts 70 and 70 which are made to oppose in the longitudinal direction (left-right direction in FIG.7 and FIG.16) in the accommodating part 40. FIG.

  Therefore, in the present embodiment, the distance between the opposed surfaces of the pair of opposed wall portions 70 is gradually shortened from the upper opening of the upper accommodating portion 40 toward the bottom wall. As a result, the longitudinal ends of the plate-like piece 66 of the assembly pin 64 fixed to the spring pin 60 gradually warp toward the upper opening side of the upper accommodating portion 40 as it goes to the bottom wall side of the upper accommodating portion 40. It is supposed to be.

  Then, when the plate-like piece 66 reaches the bottom wall of the upper housing part 40, both end portions in the longitudinal direction of the plate-like piece 66 return from the state warped to the upper opening side of the upper housing part 40 to the original state. Into the opening 72 formed in the vicinity of the bottom wall of each opposing wall 70. As a result, both end portions in the longitudinal direction of the plate-like piece 66 are positioned on the inner peripheral surface 74 of the opening hole 72 formed in each opposing wall portion 70 (particularly, on the opposite side to the fitting direction of the spring pin 60). By being locked to the upper opening side surface), the assembly pin 64 is displaced to the upper opening side of the upper housing portion 40, and further, the spring pin 60 is displaced upward in the axial direction (in the direction of removal). Displacement) is prevented.

  In the present embodiment, the state shown in FIG. 16, that is, the spring pin 60 is fitted into the lid side cylinder portion 38, and the upper surface of the plate-like piece 66 is the same height as the upper end surface of the lid side cylinder portion 38. As shown in FIG. 18, a gap is formed between the both ends in the width direction of the plate-like piece 66 and the upper accommodating portion 40 in the state where it is positioned.

  In particular, in the present embodiment, although it is not necessarily clear on the drawing, the plate-like piece 66 has a plate-like shape from the state where the upper surface of the plate-like piece 66 is positioned at the same height as the upper end surface of the lid-side cylinder portion 38 (upper accommodation portion 40). A gap is formed between the both ends in the width direction of the plate-like piece 66 and the upper accommodating portion 40 until both ends in the longitudinal direction of the piece 66 enter the opening holes 72, 72. ing. Thus, only the both longitudinal ends of the plate-like piece 66 are open on the upper side of the upper accommodating portion 40 until the spring pin 60 is inserted across the lid side cylindrical portion 38 and the main body side cylindrical portion 28. It is designed to warp to the side. As a result, the resistance from the state in which the spring pin 60 is fitted into the lid side cylinder part 38 to the state in which the spring pin 60 is inserted across the lid side cylinder part 38 and the main body side cylinder part 28 is reduced. It becomes possible.
