A chain line C shown in FIG. 20 indicates the position of the receiving surface 17 that is the receiving surface 17 formed on the upper side 4a of the game board holding frame 4 and receives the upper end of the game board 20.

  16 and 17 show the toggle clamp 53 in an unclamped state (unclamped position). In this unclamped state, the clamp member 55 rotates to the maximum extent and the front of the introduction portion 64 is at the maximum. It will be in an open state. When the toggle clamp 53 is in the unclamped state, the second pivot pin 59 is located closer to the base member 54 than the straight line D connecting the first and third pivot pins 58, 60. It is in a stable state.

Therefore, the unclamped state can be maintained even if vibration is applied during the transport of the game board holding frame 4 before the game board unit 20A is assembled. When switching from the unclamped state to the clamped state, the operation member 56 is rotated upward to switch the elastic member 57A through elastic deformation and play clearance around the pivot pins 58-60. Is possible.
In addition, as shown in FIG. 25, it can also switch by pushing the operation projection part 65 backward.

  FIG. 18 shows the toggle clamp 53 in a state immediately before clamping that does not press the operation portion 56c of the operation member 56. In this state, the third pivot pin 60 is opposite to the first pivot pin 58 from the straight line B. Is located. In this state, when the operation portion 56c of the operation member 56 is pressed backward by hand, the third pivot pin 60 is shown in FIGS. 19 and 20 through the compression elastic deformation of the spring member 57A as described above. In addition, it moves to the first pivot pin 58 side with respect to the straight line B and is in a stable clamped state.

  The position of the clamp member 55 (that is, the position of the clamp portion 66) in the clamped state varies depending on the variation in the thickness of the game board 20 (about ± 0.5 mm), so it is not always a fixed position. Absent. However, even if there is a variation in the thickness of the thick plywood game board 20, the above variation can be absorbed through elastic deformation of the spring member 57A in the straight line B direction. The regular thickness of the game board 20 is, for example, 19.0 mm.

  That is, even if there is a slight fluctuation in the front-rear direction position of the clamp portion 66 during clamping, when the operation portion 56c is pressed, as shown in FIG. 20, the third pivot pin is connected via the compression elastic deformation of the spring member 57A. 60 can be moved to the first pivot pin 58 side with respect to the straight line B to achieve a stable clamped state. At this time, a clamp state holding function is obtained by the elastic force of the compression elastic deformation of the spring member 57A. Since the spring constant of the spring member 57A in the direction of the straight line B is very large, the spring member 57A can function as a link member.

  In the toggle clamp 53, the number of members can be reduced by making the clamp member 55 as one member integrally formed, and the weight can be reduced and the manufacturing cost can be reduced. The link member 57 is not a two link member manufactured by punching a steel plate, but a single spring member 57A having a unique structure and functioning as a pair of link members. In this case, the elastic members such as torsion springs and leaf springs that were provided for holding the clamped state separately from the link members were omitted, so the number of members could be reduced, and the weight and production costs could be reduced. . In addition, as shown in FIG. 17, in the unclamped state, the second pivot pin 59 is positioned on the base member 54 side with respect to the straight line D, so that the unclamped state can be stably maintained.

Next, a procedure for attaching the game board unit 20A including the game board 20 to the game board holding frame 2 using the above-described game board attachment structure 50 will be described with reference to FIGS.
The game board holding frame 4 is attached to an assembly jig (not shown) and closed, and a pair of upper and lower toggle clamps 53 are unclamped as shown in FIG. 25 (unclamped state similar to FIG. 17). 24, the gaming board unit 20A in which the gaming board 20 is inclined from the front of the gaming board holding frame 4 (the right end side is positioned closer to the front side than the left end side) as shown in FIG. Close to the board holding frame 4, the rear half of the gaming board unit 20 </ b> A is inserted into the opening 16 of the gaming board holding frame 4, and the left end of the gaming board 20 is engaged with a pair of upper and lower engaging members 51. The game board unit 20A is rotated backward (counterclockwise in plan view) about the left end 20s of the center 20.

  Then, as shown in FIG. 25, the upper end portion of the game board 20 approaches the introduction portion 64 of the upper toggle clamp 53 and the lower end portion of the game board 20 approaches the introduction portion 64 of the lower toggle clamp 53. The operation projections 65 of the upper and lower toggle clamps 53 are pushed backward at the upper and lower ends of the game board 20 respectively. In parallel with this, the left end surface of the game board 20 is brought into contact with the receiving surface 51f of the contact piece 51h at the pair of upper and lower engaging members 51, thereby positioning in the left-right direction.

  As a result, as shown in FIG. 26, the posture of the clamp member 55 of the upper and lower toggle clamps 53 rotates to a posture close to the clamped state. Next, when the operation portion 56c of the operation member 56 of the upper and lower toggle clamps 53 is pushed rearward, the game board 20 enters a clamped state (locked state) as shown in FIG. At this time, a part of the upper end portion of the game board 20 is received by the receiving surface 17 and positioned in the front-rear direction, and a part of the lower end portion of the game board 20 is received by the receiving surface 18 and positioned in the front-rear direction. The lower end of the board 20 is received by the receiving surface 19 and positioned in the vertical direction (see FIG. 10).

The background to the idea of the above-described game board mounting structure 50 will be described.
The game board is usually made of a thick wooden plywood, but the thickness of the game board varies about ± 0.5 mm. However, the conventional clamps including the clamp disclosed in Japanese Patent Laid-Open No. 9-322971 have insufficient functions to absorb the variation in the thickness of the game board, so that the assembled game board is not stable against the holding frame. In some cases, it was a factor that reduced the ease of assembly of the game board.

  In some cases, a pair of upper and lower toggle clamps may be adopted as the clamp for fixing the game board, but when the game board unit is assembled, the posture of the clamp member of the clamp in the unclamped state could not be maintained in the desired posture. It took a lot of labor to assemble the game board unit.

  Next, operations and effects of the toggle clamp 53 and the game board mounting structure 50 of this embodiment will be described. Since the variation of the thickness of the game board 20 can be absorbed through the elastic member 57A that biases the clamp portion 66 of the clamp member 55 in the toggle clamp 53 to the game board pressing side, the thickness of the game board 20 varies. Even if it exists, the fixed state of the game board 20 to the game board holding frame 4 can be secured by the toggle clamp 53.

  The clamp member 55 is formed as an integral member, and the link member 57 has one end connected to the third pivot pin 60 and the other end connected to the fourth pivot pin 61, and functions as an elastic member. Therefore, the number of members of the dog clamp 53 can be greatly reduced, the weight can be reduced, and the production cost can be reduced.

  Since the pair of straight portions 57b and 57c of the spring member 57A as the link member 57 are formed in an intersecting shape when viewed from the side, the direction in which the pair of straight portions 57b and 57c are compressed (straight line B in FIG. 20). Direction). A clamp state maintaining function can be obtained by compression elastic deformation of the spring member 57A.

  When the game board 20 is assembled, the toggle clamp 53 can be stably held in the unclamped state as shown in FIG. 17, and the end of the game board 20 is unclamped when the game board 20 is assembled. The clamp member 55 can be switched to a position close to the clamp position by being introduced into the introduction portion 64 and pushing the operation projection 65 rearward on the game board 20, so that the game board 20 can be assembled easily and efficiently. It becomes possible.

  Next, a plurality of connectors 70A and 90A for electrically connecting various electric devices including a plurality of control boards on the game board unit 20A side to various electric devices including a plurality of control boards on the game board holding frame 4 side. , 70B, 90C and the connector mounting structure will be described.

  As shown in FIGS. 10 and 28 to 31, a connector attachment portion 30 a is provided in the vicinity of the upper end on the right end side of the lower device unit 30 fixed to the lower side portion 4 b of the game board holding frame 4. Two first frame-side connectors 70A having the same structure are provided on the right half of the attachment portion 30a, and two second frame-side connectors 90A having the same structure are provided on the left half of the connector attachment portion 30a. . The first frame-side connector 70A is a female-side connector having an elongated shape in the vertical direction, and the second frame-side connector 90A is a female-side connector having an elongated shape in the left-right direction.

  As shown in FIG. 8, two first board-side connectors connected to the two first frame-side connectors 70A are provided on the connector mounting portion 30b on the rear surface side near the lower end on the right end side of the game board unit 20A. 70B and two second panel side connectors 90C connected to the two second frame side connectors 90A are provided. The first and second board side connectors 70B and 90C are male side connectors. The first and second frame side connectors 70A and 90A are connected to various electrical devices on the game board holding frame 4 side through lead wires 70a as shown in FIG. 90C is connected to various electric devices of the game board unit 20A.

  As shown in FIG. 24, the first and second board side connectors 70B and 90C are connected to the first and first boarding operations in which the gaming board unit 20A is attached to the gaming board holding frame 4 while being rotated from the front. It is connected to the two frame side connectors 70A and 90B.

  As shown in FIGS. 28 to 31, the connector mounting portion 30 a is formed in an inclined shape that moves backward toward the right, and the front surface of the connector mounting portion 30 a (that is, the connector mounting walls 80 a and 80 b) and the game board 20. The angle α in a plan view formed by the board surface (or a plane parallel to the board surface) is about 10 °. The direction of the pin holes of the first and second frame side connectors 70A and 90A is formed orthogonal to the front surface (connector mounting walls 80a and 80b) of the connector mounting portion 30a.

  As shown in FIG. 33, the connector mounting portion 30b of the game board unit 20A is formed in an inclined shape that shifts rearward toward the right, and the rear surface of the connector mounting portion 30b (that is, the connector mounting wall 80c) and the game board 20 The angle β in a plan view formed with the board surface (or a plane parallel to the board surface) is about 10 °, and the angle β is set to an angle equal to the angle α. The direction of the terminal pins of the first and second panel-side connectors 70B and 90C is formed orthogonal to the rear surface (connector mounting wall 80c) of the connector mounting portion 30b.

  As described above, the connection direction of the first and second frame side connectors 70A and 90A and the first and second board side connectors 70B and 90C is inclined by about 10 ° with respect to the direction orthogonal to the board surface of the game board 20. The reason will be explained. As shown in FIG. 33, in the gaming board unit 20A, the connector mounting portion 30b is separated from the gaming board 20 in the rearward direction, and is provided at a site separated from the left end 20s of the gaming board 20 to the right. 24, when the game board unit 20A is attached to the game board holding frame 4, the left end 20s of the game board 20 is engaged and held with the engagement member 51 of the left side part 4c of the game board holding frame 4. The game board 20 is rotated in the direction of the arc line R around the left end portion 20s of the game board 20 (that is, the game board 20 is rotated counterclockwise in plan view).

  At this time, when the first and second frame-side connectors 70A and 90A and the first and second panel-side connectors 70B and 90C are connected, the connection direction (direction of terminal pins and pin holes) is the connector mounting portion 30a, Since it is parallel to the arc line R at 30b, the connection direction is inclined by about 10 ° with respect to the direction orthogonal to the board surface of the game board 20. Here, the above-mentioned inclination angle (about 10 °) is an example, depending on the distance in the front-rear direction of the connector mounting portion 30b with respect to the game board 20 and the separation radius from the left end 20s of the game board 20 of the connector mounting section 30b. The inclination angle (inclination angle with respect to the direction orthogonal to the board surface) is appropriately set.

Next, the first frame side connector 70A and the first panel side connector 70B will be described.
As shown in FIGS. 28 to 32, 35, and 36, the connector main body 71 of the first frame-side connector 70 </ b> A has a predetermined front-rear length. A plurality of (for example, 12) pin holes 71a for inserting and electrically connecting the plurality of terminal pins are formed in a direction perpendicular to the connector mounting wall 80a of the connector mounting portion 30a. The connector body 71 is integrally formed with a screw hole forming portion 73 that protrudes upward and downward from the upper end portion and the lower end portion thereof.

  An opening 81 through which the connector main body 71 is inserted and a pair of upper and lower screw holes 82 are formed in the connector mounting wall 80a in the right half of the connector mounting portion 30a.

The first panel side connector 70B can be smoothly connected to the first frame side connector 70A in conjunction with the mounting operation of mounting on the front side 4.

  Next, the second frame side connector 90A, the connector holding body 90B, and the second panel side connector 90C will be described. As shown in FIGS. 28 to 31 and FIGS. 37 to 40, the second frame side connector 90A is detachably mounted on a connector holding body 90B attached to the connector mounting portion 30a on the game board holding frame 4 side. Yes. A locking mechanism 91 is provided for locking the second frame side connector 90A to the connector holding body 90B through a pair of locking claws 92 provided on the connector holding body 90B. A second movable attachment mechanism 93 is also provided to attach the game board unit 20A to the game board holding frame 4 from the front side in conjunction with the attachment operation of attaching the game board unit 20A to the game board holding frame 4 from the front side. A second board side connector 90C is provided on the game board unit 20A so as to be connected to the connector 90A.

The connector holding body 90B and the second frame side connector 90A are attached to the connector attachment wall 80b on the left half of the connector attachment portion 30a. A mounting hole 94 for mounting the connector holding body 90B is formed in the connector mounting wall 80b.
The connector holding body 90B is a rectangular parallelepiped molded product having a main body front portion 95 and a main body rear portion 96 and having a mounting hole 97 in which the second frame side connector 90A is mounted. First and second engaging portions 95a and 95b are formed at both left and right ends of the main body front portion 95, and a concave portion 95c is formed in the first and second engaging portions 95a and 95b.

  A pair of upper and lower belt-like elastic portions 98 extending in the left-right direction are formed at the boundary between the main body front portion 95 and the main body rear portion 96 via slits 98a on both sides thereof, and the belt-like elastic portion 98 protrudes outward. A convex portion 98b is formed, and the left end of the convex portion 98b is inclined so as to move rightward as it extends upward or downward. A pair of upper and lower first engagement grooves 99a is formed between the first engagement portion 95a and the main body rear portion 96, and a pair of upper and lower second engagements between the second engagement portion 95b and the main body rear portion 96. A groove 99b is formed. A pair of locking claws 92 are formed on the left and right ends of the mounting hole 97. The locking claws 92 are formed at the rear end of the claw body 92a and the claw body 92a that can be elastically deformed in the left-right direction. 96 has a locking portion 92b that can be locked to the rear end wall surface 96a.

  When attaching the connector holding body 90B to the connector mounting wall 80b, the main body rear portion 96 of the connector holding body 90B is inserted into the mounting hole 94, and the convex portions 98b of the pair of belt-like elastic portions 98 are formed on the peripheral end surface of the mounting hole 94. When the connector holding body 90B is slid to the left for a short distance after the belt-shaped elastic portion 98 is elastically deformed by abutment, the wall portion 94a of the connector mounting wall 80b becomes the first engagement groove 99a. Since the wall portion 94b engages with the second engagement groove 99b and the upper and lower convex portions 98a engage with the upper and lower concave portions 94c of the mounting hole 94, the connector holding body 90B is moved in the front-rear direction and the left-right direction. The position is regulated so as not to move after being positioned.

  The second frame-side connector 90A includes, in order from the front end side, a front end flange portion 100, a pin hole forming portion 101 that is connected to the rear from the front end flange portion 100 and has a plurality of pin holes 101a, and the pin hole forming portion 101. It has a base portion 102 connected to the rear end and a rear end flange portion 103. The rear end flange portion 103 is provided with a plurality of terminal pins 103a so as to protrude rearward. The rear end flange portion 103 is formed so as to be able to pass through the mounting hole 97 of the connector holding body 90 </ b> B through elastic deformation of the pair of locking claws 92, and the pin hole forming portion 101 and the base portion 102 are formed narrower than the mounting hole 97. Has been. The front end flange portion 100 is formed with a truncated pyramid-shaped guide hole 100a whose cross section decreases toward the rear.

  In a state in which the second frame side connector 90A is attached to the connector holding body 90B, the front end flange portion 100 abuts against the front surfaces of the first and second engagement portions 95a and 95b, and a pair of rear surface sides of the front end flange portion 100 is provided. The convex portion 100b is loosely fitted into and contacted with the pair of concave portions 95c, the pin hole forming portion 101 and the base portion 102 are movably mounted in the mounting hole 97 vertically and horizontally, and the rear end flange portion 103 is mounted. The hole 97 protrudes outside the rear end and is in a state of being prevented from being detached by the pair of locking claws 92. However, since the pin hole forming portion 101 and the base portion 102 are movably mounted in the mounting hole 97 in the vertical direction and the horizontal direction, and the locking claw 92 is elastically deformable in the horizontal direction, the second frame side connector 90A. Is movable a short distance in the vertical direction and the horizontal direction with respect to the connector holder 90B. This is to enable reliable connection with the second board side connector 90C.

  Here, the pair of locking claws 92, the rear end flange 103, and the rear end wall 96a constitute a locking mechanism 91. Further, the vertical width of the pin hole forming portion 101 and the base portion 102 accommodated in the mounting hole 97 of the connector holding frame 90B is formed to be smaller than the vertical width of the mounting hole 97, and the horizontal width of the pin hole forming portion 101 and the base portion 102 is formed. Is configured to be smaller than the left and right width of the mounting hole 97, and the pin hole forming portion 101 and the base portion 102 can be moved in the left and right direction through elastic deformation of the pair of locking claws 92. It corresponds to.

Next, the second board side connector 90C will be described.
As shown in FIGS. 33 and 34, the game board unit 20A is equipped with a pair of second board side connectors 90C that can be connected to a pair of frame side connectors 90A. It is attached so as to protrude rearward from the connector attachment wall 80c of the connector attachment portion 30b. The second panel side connector 90C has a plurality of terminal pins 104 and a case member 105, and a flange portion 105a on the front end side of the case member 105 is fixed to the connector mounting wall 80c. The second panel-side connector 90C is attached orthogonally to the connector attachment wall 80c, and the plurality of terminal pins 105 are oriented in the direction orthogonal to the connector attachment wall 80c. Further, a guide inclined surface is formed at the tip of the cylindrical portion 105 a of the case member 105.

Next, how the connectors 70A, 90A, 70B, 90C and the connector mounting structure described above have been conceived will be described.
Since the plurality of frame-side connectors described in Japanese Patent Application Laid-Open No. 2006-280854 are provided so as to be slightly movable in the vertical and horizontal directions, when assembling the game board unit, some board-side connectors and some frames are provided. Since the side connector may collide and may not be smoothly connected, labor may be required for assembly of the game board unit and connection of a plurality of connectors.

  Moreover, it is common to attach the connectors so that the connection direction of the frame side connector and the board side connector is perpendicular to the board surface of the game board, but in that case, the connection direction is the same as when the game board unit is assembled. It was not always the same as the moving direction of multiple sets of connectors, and multiple sets of connectors could not be connected smoothly.

  Next, the operation and effect of the connectors 70A, 90A, 70B, 90C and the connector mounting structure will be described. Since the first movable attachment mechanism 72 and the guide mechanism 75 are provided, the first board side connector 70B can be reliably and smoothly connected to the first frame side connector 70A in conjunction with the mounting operation of the game board unit 20A.

  Further, the second frame side connector 90A attached to the connector holding body 90B can be prevented from coming off by the locking action of the locking mechanism 91, and the second frame side connector 90A can be moved vertically and horizontally via the second movable mounting mechanism 93. The second board side connector 90C can be reliably and smoothly connected to the second frame side connector 90A in conjunction with the mounting operation of the game board unit 20A.

  Since the connection direction of the board side connectors 70B and 90C with respect to the frame side connectors 70A and 90A is inclined with respect to the direction orthogonal to the board surface of the game board 20, the board side connectors 70B and 90C are separated from the game board 20 rearward. Even when arranged, the board-side connectors 70B and 90C can be reliably connected to the frame-side connectors 70A and 90A in conjunction with the mounting operation of mounting the game board unit 20A on the game board holding frame 4.

  When the game board unit 20A is mounted on the game board holding frame 4, the game board 20 is rotated counterclockwise in plan view with the left end portion of the game board 20 as the center. By setting the connection direction at the time of connector connection in consideration of the position in the front-rear direction of the board-side connectors 70B and 90C with respect to the board 20 and the turning radius from the left end of the game board 20 to the board-side connectors 70B and 90C, The side connectors 70A and 90A and the panel side connectors 70B and 90C can be reliably and smoothly connected.

  The second embodiment is an example in which a toggle clamp 53A having a structure different from the toggle clamp 53 is adopted for the game board mounting structure 50. Since the configuration other than the toggle clamp 53A is the same as that of the first embodiment, the toggle clamp 53A will be mainly described.

  As shown in FIG. 41, this gaming board mounting structure includes a gaming board holding frame 4, a pair of engaging members 51, a pair of leaf spring members (not shown), and a pair of upper and lower toggle clamps 53A. It has. 42 to 45 show the toggle clamp 53A in the clamped state, and shows the toggle clamp 53A mounted on the upper side portion 4a of the game board holding frame 4. FIG.

  The toggle clamp 53A includes a base member 110, a sub clamp member 111, a main clamp member 112, an operation member 113, a pair of link members 114, a leaf spring member 115, and first to fourth pivot pins 116. -119. The sub-clamp member 111 and the main clamp member 112 form an introduction portion 64A for introducing the upper end portion of the game board 20. The base member 110 is formed in a U shape by the substrate portion 110a and the pair of side plate portions 110b, and the sub-clamp member 111 is also formed in a U shape by the substrate portion 111a and the pair of side plate portions 111b. The substrate portion 112a and the pair of side plate portions 112b are formed in a U shape, and the operation member 113 is also formed in a U shape by the substrate portion 113a and the pair of side plate portions 113b.

  The sub-clamp member 111 includes a pair of operation projections 65 </ b> A at the rear end thereof, and a middle portion in the front-rear direction of the sub-clamp member 111 is provided at the lower part of the pair of side plate portions 110 b of the base member 110 with a first pivot pin 116. It is connected. The main clamp member 112 is L-shaped in a side view, and the upper end portions of the pair of side plate portions 112b are connected to the front end portions of the pair of side plate portions 111b of the sub clamp member 111 by the second pivot pin 117. Yes. An operation portion 112 c is formed at the lower end portion of the substrate portion 112 a of the main clamp member 112.

  The lower end portions of the pair of side plate portions 113b of the operation member 113 are coupled to the second pivot pin 117, and an operation portion 113c protruding upward is formed on the substrate portion 113a of the operation member 113. The lower ends of the pair of link members 114 are connected to the rear ends of the pair of side plate portions 113b of the operation member 113 by the third pivot pins 118, and the upper ends of the pair of link members 114 are the fourth pivot pins. 119 is connected to a pair of side plate portions 110 b of the base member 110.

  The leaf spring member 115 (corresponding to an elastic member) is L-shaped in a side view, and its upper end plate portion 115a is fixed to the lower surface side of the sub clamp member 111, and the front end plate portion 115b of the leaf spring member 115 is the main. Abutting against the front surface of the substrate portion 112a of the clamp member 112, the leaf spring member 115 strongly biases the clamp portion 66A of the main clamp member 112 toward the introduction portion 64A, and the game board is connected via the leaf spring member 115. The thickness variation of 20 can be absorbed.

However, since a pair of locking portions 111c for receiving the main clamp member 112 is formed at the lower end on the front end side of the pair of side plate portions 111b of the sub clamp member 111, the main clamp member is not fixed when the game board 20 is not fixed. 112 is held in a slightly rotated state toward the introduction portion 64A.
However, when the game board 20 is fixed, the main clamp member 112 is not locked by the pair of locking portions 111c.

Also in the toggle clamp 53A described above, in the unclamped state, the second pivot pin 117 is located on the line connecting the first pivot pin 116 and the third pivot pin 118 or closer to the base member 110 than the line. Since a stable unclamped state can be maintained, even when this toggle clamp 53A is employed, the game board unit 20A is assembled to the game board holding frame 4 in the same manner as in the first embodiment, and the game board 20 is fixed. can do.
The operations and effects of the toggle clamp 53A and the game board mounting structure described above are substantially the same as those in the first embodiment, and thus the description thereof is omitted.

Next, an example in which the above embodiment is partially changed will be described.
(1) The positional relationship of the first to third pivot pins 58 to 60 is changed by changing the toggle clamp 53, and the upper and lower toggle clamps 53 are unclamped as shown in FIG. Thus, while the support frame 2 and the game board holding frame 4 are transported by the transport means, the clamp member 55 may be rotated by the vibration during the transport and may have a downward posture as shown in FIG. In this case, the following frictional force adding mechanism for applying a frictional force between the base member 54 and the clamp member 55 may be employed.

  As a first frictional force adding mechanism, a spring washer is attached to the first pivot pin 58 between the lower arm portion 62 of the base member 54 and the side plate 55b of the clamp member 55 on both the left and right sides of the base member 54. A frictional force is applied between the arm 62 and the clamp member 55.

As a second frictional force adding mechanism, the distal end portions of the left and right lower arm portions 62 of the base member 54 are slightly bent so as to approach the clamp member 55 side, and the distal end portions are always in contact with the side plate 55b of the clamp member 55. As a result, a frictional force is applied between the lower arm 62 and the clamp member 55.
As a third frictional force adding mechanism, small engaging protrusions are formed on both the left and right side plates 55b of the clamp member 55, and the left and right lower arms 62 of the base member 54 are in an unclamped state. Sometimes an engagement recess is formed that is lightly engaged with the engagement projection.

When the above frictional force adding mechanism is provided, the toggle clamp 53 can be held in an unclamped state by the frictional force, so that the end of the game board 20 can be smoothly connected to the introduction part 64 when the game board unit 20A is assembled. It can be introduced and the operation projection 65 can be pushed backward to switch the toggle clamp 53 to the state immediately before clamping.
The above frictional force adding mechanism can be similarly applied to the toggle clamp 53A.

(2) The toggle clamp of the present embodiment shows two examples, and various toggle clamps other than these toggle clamps can be adopted.

(3) The first and second frame side connectors 70A and 90A may be constituted by male connectors, and the first and second panel side connectors 70B and 90C may be constituted by female connectors. The structures of the connectors 70A, 90A, 70B, and 90C are not limited to those of the above-described embodiment, and connectors having various structures can be employed.

(4) In addition, those skilled in the art can implement the present invention in a form in which various modifications are added without departing from the spirit of the present invention.
