  FIG. 2 is a perspective view of the slot machine 100 described above with the front door 101 opened from the main body 201. Various devices are attached to the inside of the main body 102 and the back side of the front door 101. Here, attention is focused on the attachment process of the long fastening member 300 that is fastened to the lower back of the front door 101. The fixing member 300 is provided with a plurality of screw holes 301 for screwing with the same standard screw 400.

  Briefly explaining this screwing operation, the screw storage device 500 in which a plurality of screws 400 are stored is held with one hand, the holding portion 311 of the screwdriver 310 is held with the other hand, and the shaft 312 of the screwdriver 310 is stored in the screw. The screw 400 is inserted into the rear end opening 502 of the tool, the tip opening 501 of the screw storage tool 500 is aligned with the screw hole 301, the screwdriver 310 is pushed in strongly, and the screwdriver 310 is turned in the screw tightening direction. The screw hole 301 is fastened (see FIG. 3).

  An example of the structure of the screw 400 that can be screwed by the above working method is shown in FIGS. 4 (a1) and 4 (a2). A large-diameter head 402 is formed at one end of a shaft 401 having a thread formed on the outer peripheral surface, and a cutting edge 313 of a screwdriver 310 that is, for example, a Phillips screwdriver (the tip of the shaft 312) is formed on the head 402. The front end 401a, which is the other end of the shaft 401 (the end where the head 402 is not formed), has an engaging portion 402a (cross hole) that engages with the engaging portion of the head 402. The engagement shape can be engaged with 402a (a cross having the same shape as the blade edge 313 of the screwdriver 310).

  That is, in the screw 400 having an engagement shape in which the distal end portion 401 a of the shaft body 401 can be engaged with the engaging portion 402 a of the head portion 402, the other screw 400 is connected to the engaging portion 402 a of the head portion 402 of the screw 400. When the screw 400 is connected in series by engaging the front end 401a of the shaft body 401 (in a state where the screw tightening rotation shafts are aligned in a straight line), the engaging portion of the head 402 of the screw 400 on the rear end side Since all the screws 400 connected in series rotate in the screw tightening direction by engaging the blade edge 313 of the screwdriver 310 with the screwdriver 402a and rotating in the screw tightening direction, the screw holes 301 are aligned with the screw holes 301. The tip side screw 400 can be tightened into the screw hole 301.

  And an example of the structure of the screw accommodation tool 500 which accommodates the screw 400 of the structure mentioned above in series is shown to Fig.5 (a1) and (a2). The external appearance of the screw storage device 500 is a long cylindrical shape whose both ends are open, and a screw storage space 503 is formed therein. That is, the screw storage space 503 is a substantially cylindrical space that communicates from the front end opening 501 through which the screw 400 to be fixed to the screw hole 301 is fed to the rear end opening 502 through which the blade tip 311 of the screwdriver 310 is inserted, and the diameter thereof is The outer diameter of the head 402 of the screw 400 to be stored is set to be slightly larger.

  A protrusion-shaped screw receiving projection 504 is formed at an appropriate position on the front opening 501 side on the inner surface of the screw storage device 500, and the head 502 of the screw 400 is hooked on the screw receiving projection 504, whereby the rear end opening 502. It is possible to prevent the screw 400 inserted from the outside from being removed from the tip opening 501. Further, the screw receiving projection 504 is formed of an elastic material, or the screw receiving projection 504 is integrally formed with the screw storage device 500 formed of a synthetic resin or the like, so that an appropriate pressing force (screw tightening operation) is applied to the screw 400. When a force that does not cause a burden on the operator performing the above operation is applied, the head portion 402 of the screw 400 passes through the screw receiving convex portion 504 and comes out of the tip opening 501.

  The screw receiving convex portion 504 formed in this way is “to prevent the screw from coming out to the tip opening by contacting the head of the screw that is the most at the tip opening side in the normal state, from the rear end opening to the tip opening side. When an appropriate pressing force is applied, it functions as a “stopper means that allows the screw to escape to the tip opening”. Note that if the tip opening 501 is faced downward with a large number of screws 400 stored in the screw storage space 503, the total weight of the stored screws 400 is applied to the receiving convex portion 504. The screw receiving convex portion 504 needs to be configured so that the screw 400 can be stopped in the screw accommodating hollow portion 503 against the pressing force due to the total weight. In addition, the protruding shape of the screw receiving projection 504 is gently inclined from the rear end opening 502 side toward the front end opening 501 side, so that the screw 400 can be smoothly pushed out toward the front end opening 501. Anyway.

  In addition, although the arrangement position of the screw receiving projection 504 is not particularly limited, in the present embodiment, the distal end portion 401a of the shaft body 401 of the screw 400 closest to the distal end opening 501 is the opening end of the distal end opening 501. A screw receiving convex portion 504 is provided at a position where the screw 400 is caught at the head portion 402 at a position where the screw 400 is not further protruded, and the tip portion 401a of the screw 400 is protruded from the tip opening 501 so as not to get in the way. Of course, the arrangement position of the screw receiving projection 504 is adjusted so that the tip 401 a slightly protrudes from the tip opening 501, and the tip 401 a of the screw 400 is lightly inserted into the screw hole 301. Positioning may be facilitated. Alternatively, the screw receiving projection 504 is provided in the vicinity of the tip opening 501, and the shaft body 401 of the most distal screw 400 is normally housed in the screw housing 500 in a state of protruding appropriately from the tip opening 501. Things can be used.

  Further, the screw that can be stored in the above-described screw storage device 500 and can be tightened is not limited to the screw 400 having the cross tip portion 401a and the cross hole engagement portion 402a. Various types of blades can be used according to the cutting edge 313. For example, when aligning with the blade edge of a flat-blade screwdriver, a single groove-like engaging portion 412a is provided on the head 412 as shown in FIGS. 4B1 and 4B2, and this engaging portion A tip portion 411a having a shape that can engage with 412a (the same minus shape as the blade of a minus driver) is provided on the shaft body 411. When a hexagon wrench is used as a screwdriver, an engaging portion 422a, which is a hexagonal recess, is provided on the head 422 as shown in FIGS. 4C1 and 4C2, and the engaging portion 422a is provided. The shaft body 421 is provided with a tip portion 421a having a shape that can be engaged with the hexagonal wrench (the same hexagonal shape as the hexagon wrench).

  Further, the screw storage device for storing these screws 400, 410, 420, etc. is not limited to the screw storage device 500 described above. For example, a screw housing 510 shown in FIG. 5B (a screw housing hollow 513 communicating from the front end opening 511 to the rear end opening 512 is formed, and a screw receiving convex portion 514 is provided at an appropriate position on the inner surface on the front end opening 511 side. ), A taper surface 515 may be formed on the rear end opening 512 side to facilitate insertion of the screw 400 and the like into the screw storage space 513.

  Here, as the screw receiving projections 504 and 514 provided in the screw storage devices 500 and 510, the bulging inclination from the front end openings 501 and 511 toward the rear end openings 502 and 512 is changed from the rear end openings 502 and 512 to the front end opening 501. , 511 shape that is steeper than the bulging slope toward the tip opening 511 (the most bulging portions of the screw receiving projections 504 and 514 are formed closer to the tip openings 501 and 512, and are the most steep than the slope from the most bulging portion toward the tip opening 501. If the inclination from the bulging portion toward the rear end opening 502 is made gentler, the screw 400 and the like can be easily pushed out from the screw storage devices 500 and 510 during the screw tightening operation, and once the screw receiving convexity The screw 400 or the like pushed out beyond the portions 504 and 514 is difficult to return into the screw storage empty portions 503 and 513 beyond the screw receiving convex portions 504 and 514.

  Alternatively, as in a screw storage tool 520 shown in FIG. 5C, a screw storage empty portion 523 communicating from the first opening 521 to the second opening 522 is formed, and the first opening 521 is located at a distance L from the first opening 521. The screw receiving protrusion 524a is provided with a second screw receiving protrusion 524b at a distance L from the second opening 522, and the first opening 521 and the screw receiving protrusion 524a are arranged in accordance with the direction of the screw 400 placed in the screw storage space 523. If the second opening 522 can be used as both a front end opening and a rear end opening, the direction in which the screw 400 is inserted from the position where the screw receiving projections 504.514 are provided, as in the screw storage devices 500 and 510 described above. Therefore, it is possible to improve the workability. Moreover, in the above-described screw storage devices 500 and 510, when the rear end openings 502 and 512 are directed downward, the screws 400 placed in the screw storage empty portions 503 and 513 are removed, but in the screw storage device 520, the first Regardless of whether the opening 521 is directed downward or the second opening 522 is directed downward, the screw 400 placed in the screw storage space 523 will not fall off.

  When the structure is usable in either direction as in the case of the screw storage tool 520, the shape of the first screw receiving convex portion 524a provided on the first opening 521 side is a bulging slope toward the second opening 522 from the first opening 521. And the shape in which the bulging slope from the second opening 522 toward the first opening 521 is the same slope (the approximate center of the first screw receiving convex portion 524a is the most bulging portion, and the slope on the first opening 521 side is And the shape of the second screw receiving convex portion 524b provided on the second opening 522 side is a bulging inclination from the second opening 522 toward the first opening 521, and The shape in which the bulging slope from the first opening 521 toward the second opening 522 is the same slope (the approximate center of the second screw receiving convex portion 524b is the most bulging portion, and the slope on the second opening 522 side and the first opening 521 Side slope is almost the same shape) If this is the case, the screw 400 or the like is pushed into the first opening 521 so that the screw 400 protrudes beyond the first screw receiving convex portion 524a and is stored in the screw storing empty portion 523, and the head 402 hits the first screw receiving convex portion 524a. Pressing the screw 400 or the like from the second opening 522 side to push it out of the first opening 521 beyond the first screw receiving convex portion 524a, and pushing the screw 400 or the like from the second opening 522 into the second screw receiving convex portion The operation of storing the screw in the screw storage space 523 beyond 524b and the second screw receiving protrusion 524b by pushing the screw 400 or the like with the head 402 against the second screw receiving protrusion 524b from the first opening 521 side. Can be pushed out from the second opening 522 in substantially the same manner, so that the screw 400 or the like can be stored in either of the first and second openings 521 and 522. Not impaired work efficiency in the work and screwing operation. Moreover, it is easy to make a structure in which the screw 400 or the like is unlikely to fall out of the first and second openings 521 and 522 regardless of which of the first and second openings 521 and 522 is housed.

  The stopper means for stopping the stored screw in the screw storage space is not limited to the small protrusions such as the above-described screw receiving projections 504, 514, 524a, and 524b. Any configuration may be used as long as it has both a slip-out prevention function and a function for allowing a pull-out in a pressurizing operation during screw tightening.

  For example, in the screw container 530 shown in FIGS. 5 (d1) and (d2), a U-shaped notch (screw fixing) is formed on the peripheral surface of a hollow cylinder formed of an elastic material (for example, soft synthetic resin). Two vertical cutouts parallel to the axial direction and separated by an appropriate separation distance and one horizontal cutout connecting the end of the vertical cutout at the side of the tip opening 531) are provided as a screw receiving swing piece 534, and this screw A screw receiving portion 534a is formed on the inner surface of the receiving swing piece 534 on the side of the swingable tip opening 531, and the screw receiving swing piece 534 normally protrudes from the inner wall surface. Therefore, when the head 400a of the screw 400 hits the screw receiving portion 534a to prevent the head 400a from coming out of the tip opening 531 and a pressing force acts in the direction of pushing out the screw 400 from the tip opening 531, the head 402 of the screw 400 is screwed. The screw receiving portion 534a is pushed along the taper surface of the receiving portion 534a, and accordingly, the screw receiving portion 534a is retracted from the screw storing empty portion 533 (a state indicated by a broken line in FIG. 5 (d2)), and the head of the screw 400 When 402 is removed from the screw receiving portion 534a, the elastic screw receiving swinging piece 534 quickly returns to the normal state, so that the screw receiving portion 534a returns to a state where it protrudes from the inner wall surface to the screw storage empty portion 533, The head 400a of the subsequent screw 400 is received.

  In the screw storage tool 530, the upright surface orthogonal to the feeding direction of the screw 400 is set so that the end portion on the tip opening 531 side of the screw receiving swing piece 534 becomes the most bulged portion of the screw receiving portion 534a. The screw 400 once pushed over the screw receiving portion 534a is pushed back into the screw housing empty portion 533 again, and the head portion 402 of the screw 400 is moved from the tip opening 531 side. Even if it hits the upright surface of the screw receiving portion 534a, it is difficult for the screw receiving portion 534a of the screw receiving swinging piece 534 to act as a force for retreating the screw receiving empty portion 533 from the inside to the outside. Will hold the normal state which protrudes in the screw accommodation empty part 533. Therefore, it is possible to effectively prevent the screw 400 once pushed out toward the screw hole 301 from returning again into the screw housing empty portion 533 during the screw tightening operation or the like, which can contribute to improvement in workability.

  Further, the present invention is not limited to the case where the stopper means is provided only for the screw on the tip opening side. For example, the stopper means is provided for each screw, and each screw is stably stored by the stopper means in the screw storage space. You may do it. In such a case, the stored screws are appropriately engaged with each other (the engaging portion of the screw head adjacent to each other and the tip of the screw shaft portion are appropriately engaged, and the screw on the rear end side is screwed) It is necessary to increase the formation position accuracy of the stopper means so that when the screw is rotated, the most advanced screw can be properly rotated.

  The above-described screw storage devices 500 to 530 may be manufactured by integral molding of resin, fusion of a plurality of parts, or the like, and may be manufactured by processing a metal pipe. A method for manufacturing a screw storage tool will be described with reference to FIG. In this manufacturing method, the screw storage tool 520 in which the first and second screw receiving protrusions 524a and 524b are respectively provided at the distance L from the first opening 521 and the second opening 522 is manufactured.

  In order to produce the screw storage device 520, a flexible rectangular flat plate obtained by processing soft rubber, foamed resin or the like into a thin plate shape (a square plate in which all four corners are right angles and the long side and the short side are equal) A sheet material 600 including a flat plate is used. The sheet material 600 includes an inner side 601 that is wound inside, an outer side 602 that faces the inner side 601, a first side 603 that is an edge of the first opening 521, and a second opening 522. A stopper member 605 serving as the first and second screw receiving convex portions 524a and 524b is fixed to a required position on the inner surface 600a on the winding side of the sheet material 600. An adhesive portion 606 is formed in a strip shape on the inner surface 600 a of the paper, and the adhesive portion 606 is protected by a release paper 607.

  In addition, on the inner surface 600a of the sheet material 600, an index portion 608 serving as an index of a position where the inner side 601 where the winding starts is brought into contact is provided, so that a screw storage empty portion 523 corresponding to the size of the screw to be stored can be formed. Convenience is improved. For example, assuming that the diameter of the screw head to be stored is R, the inner side 601 can be brought into contact with the position of R × π from the inner side 601 (a position slightly further in consideration of the thickness of the sheet material 600) to start winding. For example, since a screw storage space that can store a screw having a head diameter R can be formed, a scale indicating a separation distance from the inner side 601 to the outer side 602 may be provided as the indicator portion 608. Alternatively, the index portion 608 may be described by describing the position where the inner side 601 starts to be brought into contact with the inner side 601 according to a screw standard (JIS, ISO, or the like).

  When the inner side 601 of the sheet material 600 configured as described above is positioned with the indicator portion 608 as a guide, the inner surface 600a is rolled up, and the adhesive portion 606 exposed by peeling off the release paper 607 is attached to the outer surface 600b. The screw storage tool 520 in which the sheet material 600 is held in a cylindrical shape and a screw storage space corresponding to the screw head diameter is formed therein can be produced.

  7 (a) and 7 (b) show a connecting screw member 700, which has the appearance that the above-described screws 400 to 420 are connected and fixed in series. That is, a first screw forming portion 710 including a first shaft body 711 having a thread on the outer peripheral surface and a first head 712 having a hexagonal shape, a second shaft body 721 having a thread on the outer peripheral surface, and a hexagon. A second screw forming portion 720 including a second head portion 722 having a shape, a third screw forming portion 730 including a third shaft body 731 having a thread on the outer peripheral surface, and a third head portion 732 having a hexagonal shape, The first separation part 701 is formed at the connection part between the first screw formation part 710 and the second screw formation part 720, and the connection part between the second screw formation part 720 and the third screw formation part 730. The second separator 702 is formed.

  Further, the head portion 732 of the third screw forming portion 730 is provided with an engaging portion 732a (for example, a cross-shaped engaging groove) that can engage with the blade edge 313 of the screwdriver 310. When the screw forming portion 730 is rotated in the screw tightening direction, the connecting screw member 700 is rotated, and the shaft body 711 of the first screw forming portion 710 on the foremost side is also rotated in the screw tightening direction. Therefore, the tip 711a of the shaft body 711 of the first screw forming portion 710 is aligned with the screw hole 301, and the connecting screw member 700 is rotated by the screwdriver 310 in the screw tightening direction, whereby the first screw forming portion 730 is moved. It can be fixed to the screw hole 301.

  The first separating portion 701 can easily separate the first screw forming portion 701 and the second screw forming portion 702 by a predetermined required separating method. In this configuration example, the first separation portion 701 is configured by connecting the first screw formation portion 710 and the second screw formation portion 720 in detail. The thickness of the details that can function as the first separation portion 701 may be set as appropriate depending on the screw material. For example, in a general brass screw, the details are approximately half the diameter of the shaft body 711. Should be formed. In this way, it is not a burden on the operator when it is desired to separate the first screw forming portion 701 and the second screw forming portion 702 while maintaining the strength at which the first separating portion 701 is not separated by the screw tightening torque during screw tightening. It can be separated with a certain amount of force.

  As an example of the separation method of the first separation portion 701 in the connecting screw member 700, the second screw formation portion 720 and the third screw formation are performed after the shaft body 711 of the first screw formation portion 710 is fixed to the screw hole 301. The connecting screw member storage tool (described in detail later) in which the portion 730 is stored is bent (connecting so that the rotation axis of the second screw forming portion 720 forms an angle with respect to the rotation axis of the first screw forming portion 710). By pushing the screw member storage device from the side), the first separation portion 701 is folded and the first screw formation portion 710 is separated from the second screw formation portion 720. The separated first screw forming portion 701 becomes an independent screw (in this embodiment, a hexagonal bolt), and can be tightened or removed using a hexagonal head 712 with a spanner or a wrench. In the case of the connecting screw member 700 using a soft metal, the first separating portion 701 may not be easily broken only by bending the connecting screw member storage tool once, but in such a case, a different direction (or the same) The connection screw storage tool may be bent many times in the direction), or the connection screw member storage tool may be twisted more strongly in the screw tightening direction and the first connection portion 701 may be twisted off.

  The second separation part 702 has the same detailed connection structure as the first separation part 701. After the shaft body 721 of the second screw formation part 720 is fixed to the screw hole 301, the third screw formation part 730 is accommodated. By bending the connecting screw member storage tool, the second separation portion 702 is folded, and the second screw formation portion 720 is separated from the third screw formation portion 730. Similarly to the first screw forming portion 701, the separated second screw forming portion 720 also becomes an independent screw (in this embodiment, a hexagon bolt), and is tightened or removed using a hexagonal head 722 with a spanner or a wrench. You can.

  The last remaining third screw forming portion 730 functions as a single screw, and can be tightened or removed with a screwdriver 310 using the engaging portion 732a of the head 722, and the first and second screw forming portions 710 are used. , 720, the hexagonal head 732 can be used to tighten or remove with a spanner or wrench.

  In addition, although the connection screw member 700 of this embodiment connected the 1st-3rd screw formation part 710-730 via the 1st, 2nd isolation | separation part 701,702, not only this but two screw formation The connecting screw member may be formed from the portion, or the connecting screw member may be formed from four or more screw forming portions. Further, the shape of the tip end portion 711a of the shaft body 711 in the first screw forming portion 710 is engaged with the engaging portion 732a of the head portion 732 in the third screw forming portion 730 so that a plurality of connecting screw members 700 can be connected. It is good also as a shape to obtain.

  In addition, the first and second separation portions 701 and 702 are not limited to the above-described detailed connection structure, and the first screw formation portion 710 and the second screw formation portion 720 are easily separated from each other, and the second screw formation portion 720 Any structure may be adopted as long as the third screw forming portion 730 is easily separated. For example, the connecting portion between the rear surface of the head 712 of the first screw forming portion 710 and the tip of the shaft body 721 of the second screw forming portion 720, and the rear surface of the head 721 of the second screw forming portion 720 and the third screw forming portion 730. If a cut (generally cut to about half of the shaft body) is formed in the connecting portion with the tip of the shaft body 731 and this is used as the first and second separation portions 701 and 702, the first screw forming portion 710 is formed. After connecting the shaft body 711 or the shaft body 721 of the second screw forming portion 720 to the screw hole 301, the connecting screw member storage tool in which the second screw forming portion 720 and the third screw forming portion 730 are stored, The connecting screw member storage tool in which the three screw forming portion 730 is stored is pushed from the side to bend so as to enlarge the cuts of the first and second separating portions 701 and 702, and the first screw forming portion 710 and the second screw Forming part 720 Away, or a second screw forming portion 720 and a third thread forms 730 may be caused to separate.

  FIG. 7 (c) shows a connection screw member storage 810 that stores the connection screw member 700 described above, and whether the heads 712, 722, 732 of the first to third screw formation portions 710-730 pass through. A rear end opening 812 (screwdriver) from a front end opening 811 in the connecting screw member 700 (an opening for feeding the shaft body 711 of the first screw forming portion 710 on the most distal side to the screw hole) in the connecting screw member 700 The connecting screw member housing empty portion 813 communicates with the blade edge 313 of 310, and is connected to the tip opening 811 side of the connecting screw member containing empty portion 813. Is provided.

  The retaining protrusion 814 normally abuts against the head 712 of the first screw forming portion 710 on the foremost side to prevent the connecting screw member 700 from coming out to the tip opening 811, and When an appropriate pressing force is applied from the end opening 812 toward the tip opening 811, it functions as a stopper unit that allows the head 712 of the first screw forming portion 710 to escape to the tip opening 811. The stopper means for stopping the stored connecting screw member 700 in the screw storage space 813 is not limited to the small protrusions such as the screw receiving protrusions 504, 514, 524a, and 524b described above. Any configuration may be used as long as it has both a function for preventing the connection screw member 700 from coming off in a normal state and a function for allowing the connection screw member 700 to come off during the pressurizing operation. Further, when the retaining projection 814 is used as a stopper means, it may be provided only at one place on the inner wall surface, or the retaining projection 814 may be provided on all six surfaces.

  When the connecting screw member 700 is stored in the connecting screw member storage tool 810 described above and the first screw forming portion 710 on the most distal side is fixed to the screw hole 301, for example, a screwdriver inserted from the rear end opening 812 is used. The cutting edge 313 of 310 is engaged with the engaging portion 732a of the head portion 732 of the third screw forming portion 730 so that the connecting screw member 700 can be rotated in the screw tightening direction, so that the shaft body 711 of the first screw forming portion 710 is obtained. The tip portion 711a of the first screw forming portion 710 is aligned with the screw hole 301 and the connecting screw member 700 is pressurized toward the tip opening 811 via the screwdriver 310, thereby preventing the head portion 712 of the first screw forming portion 710 from coming off. The screwdriver 310 is rotated in the screw tightening direction so that the screw thread of the head 711 of the first screw forming portion 710 is screwed into the screw groove of the screw hole 301.

  At this time, since the connecting screw member storage tool 810 rotates together with the connecting screw member 700 in the screw tightening direction, the second screw forming portion 720 and the third screw forming portion 730 stored in the connecting screw member storage space 813 are used. Since the torsional moment does not occur in the second separating portion 702 that connects the two, the second separating portion 702 having the detailed coupling structure is not broken. Further, when the screw tightening operation is performed with the head 712 of the first screw forming portion 710 being fixed in the connecting screw member housing empty portion 813, the first screw forming portion 710 and the second screw forming portion 720 are used. Since the torsional moment does not occur in the first separation part 701 that connects the two, the first separation part 701 having the detailed coupling structure can be effectively prevented from being broken.

  After the shaft body 711 of the first screw forming portion 710 is tightened in the screw hole 301, the connecting screw member storage tool 810 in the state in which the second screw forming portion 730 and the third screw forming portion 740 are stored is tilted. A force that bends the first separation portion 701 that is a connecting portion between the first screw formation portion 710 and the second screw formation portion 720 acts, and when the bending limit is exceeded, the first separation portion 701 breaks, and the first screw formation portion 710 becomes a screw. It remains as a screw tightened in the hole 301. In addition, you may make it isolate | separate the 1st isolation | separation part 701 with cutting tools, such as a nipper.

  The above-described hexagonal column-shaped connecting screw member storage tool 810 rotates in the screw tightening direction together with the stored connecting screw member 700. However, the present invention is not limited to this, and the screw storage tools 500, 510, 520, and 530 described above. As described above, only the internal connecting screw member 700 may be rotated in the screw tightening direction. In such a case, the heads 712, 722, and 732 of the hexagonal first to third screw forming portions 710, 720, and 730 can be stored as in the connection screw member storage tool 820 shown in FIG. A cylindrical body having a large inner diameter.

  The connection screw member storage tool 820 forms a connection screw member storage space 823 that communicates from the first opening 821 to the second opening 822, and the first retaining protrusion 824 a is located at a distance L from the first opening 821. The second retaining protrusion 824b is provided at a distance L from the second opening 822, and the first opening 821 and the second opening 821 are arranged in accordance with the direction of the connecting screw member 700 placed in the connecting screw member housing empty part 823. The opening 822 can be used as a front end opening or a rear end opening.

  Although the first and second retaining protrusions 824a and 824b are annular protrusions, all six corners of the hexagonal heads 712, 722, and 732 are caught. If one corner of the heads 712, 722, and 732 hits the first and second retaining protrusions 824a and 824b, the retaining function can be exerted, so the first and second retaining protrusions 824a and 824b are A structure in which one or two corners of the heads 712, 722, and 732 are hooked by providing an arc of about 60 ° may be used.

  Further, when the screwing operation of the connecting screw member 700 stored using the cylindrical connecting screw member storage tool 820 is performed, the head 732 of the third screw forming portion 730 on the rearmost end side is screwed by the screwdriver 310. Since the shaft body 711 of the first screw forming portion 710 on the foremost side is screwed into the screw hole 301 by turning in the tightening direction, it occurs in the first separating portion 701 and the second separating portion 702 having the detailed connection structure. The first and second separation portions 701 and 702 are prevented from being easily separated by the torsion moment from the first screw formation portion 710, the second screw formation portion 720, and the third screw formation portion 730. It is necessary to ensure the connection strength.

  As described above, the screw and the screw storage device according to the present invention have been described as some embodiments. However, the present invention is not limited to these embodiments, and any equivalent technique can be used as long as the configuration described in the claims is not changed.
