It has an extending guide portion 19. On the other hand, a plurality of (for example, five) locking holes 21 as engaged parts are formed at predetermined intervals in the protruding portion of the inner rail 12 and in the vicinity thereof. A locking projection 22 having a substantially inverted T-shape on the front is integrally formed as an engaging portion at the lower portion of the ball receiving member 17 so as to correspond to the locking holes 21.

Although the ball receiving member 17 is inserted from the front side, the locking projection 22 is formed slightly larger than the locking hole 21, and the locking projection 22 resists its own elastic force in the locking hole 21. It is retained by its elastic force by being fitted in and is prevented from being displaced especially along the inner rail 12 by the engaging relationship between the engaging hole 21 and the engaging projection 22. As described above, when the ball receiving member 17 is attached, the ball receiving member 17 can be attached independently, so that a separate member such as a screw is not required, which not only reduces the number of parts and the number of assembly steps but also facilitates the replacement work of the ball receiving member 17. Become.

Both guide portions 19 of the ball receiving member 17 have an arc shape conforming to the inner rail 12, and a plurality of ribs 23 are formed on the lower surface thereof at predetermined intervals. The presence of these ribs 23 not only reinforces the guide portion 19, but also forms a slight gap between the inner rail 12 and the guide portion 19, so that the guide portion 19 has a large cushioning property due to its own elastic force. Cushioning properties that exceed are provided.
Therefore, even when the game ball B hits the guide portion 19,
The cushioning property absorbs the impact force, and as a result, it is possible to prevent the inner rail 12 and the front frame 3 from being damaged as much as possible. The reason why the ball receiving member 17 is provided in the lower region of the inner rail 12 is that the game ball B may collide with such a portion at high speed, so that the impact is mitigated to prevent damage to the portion. This is because the front frame 3 is prevented from being damaged and the pachinko machine 1
In addition to prolonging the service life, the front frame 3 can be reused only by replacing the game board 5.

The lead-out portion 18 is arranged corresponding to the protruding portion of the inner rail 12, and the inner rail 12
Are arranged so as to project downward from the arc shape formed by. Then, most of the game balls B that have fallen to the lower part of the game board 5 are guided from the guide portion 19 toward the lead-out portion 18, and are guided through the lead-out portion 18 toward the ball discharge path (not shown). It is like this. The lead-out portion 18 is also integrally formed with a plurality of ribs 24 for reinforcing or cushioning the game ball B.

A so-called out port 25 is formed by the game board 5, the opening portion formed by the lead-out portion 18, and further the lower frame of the glass door frame 4.
Therefore, unlike the prior art in which the game board is subjected to the router processing to form the out port, in the present embodiment, the game board 5 needs to be subjected to the router processing to form the out port 25. Absent. Also, the outlet 25 is
It is covered by the lower frame of the glass door frame 4, and is provided at a position where it is difficult to visually recognize it during a normal game. Therefore, the outlet 25 is opened in the falling direction and is led out as if it were sucked.

Incidentally, the lower surface of the protruding portion and the lead-out portion 18 forming the outlet 25 is inclined from the front side to the back side, and guides the falling game ball B to the back side. . This prevents the ball clogging at the outlet 25. Further, the front portion of the ball receiving member 17 has a folded shape, and the presence of this folded portion prevents illicit acts using a tapered member such as a pin or a wire.

The ball receiving member 17 has a lead-out portion 18
Are placed on the lower frame of the glass door frame 4 and the other portions are placed on or close to the glass attached to the glass door frame 4, respectively. Therefore, as described above, the ball receiving member 17 is simply placed on the front side. Although it is only fitted from above, the ball receiving member 17 is reliably prevented from falling off when the glass door frame 4 is closed.

The cushioning member such as the ball receiving member 17 may be directly fixed to the game board 5 or the inner rail 12 with a screw or an adhesive means. By adopting a molding method such as two-color molding, when molding the front frame 3,
The cushioning member may be provided integrally with the inner rail 12. However, in this case, as the material of the cushioning member, one having a better shock absorbing action than the inner rail 12 (for example, general synthetic resin such as polyolefin such as polyethylene and polypropylene, elastic resin material such as EPDM) It is preferable to use.

On the other hand, in the outer rail 13, at a position corresponding to the maximum flight portion of the game ball B (upper right part in FIG. 2: this corresponds to the tip of the outer rail 13), a return rubber as a cushion member. 26 is attached. Therefore, the game ball B, which is launched with a momentum higher than a predetermined value, hits the return rubber 26 and is repelled. Further, on the inner side surface of the outer rail 13, in order to make the flight of the game ball B smoother, a sliding plate 27 as a long metal strip made of stainless steel is attached. Therefore, it can be said that the sliding plate 27 is a component of the outer rail 13.

Explaining in more detail how the sliding plate 27 is attached, an end locking groove 28 is formed near the base end of the outer rail 13 (near the game ball B launching portion). Further, as shown in FIGS. 7A and 7B, a plurality of locking protrusions 31 and support protrusions 32 are provided on the outer rail 13 along the longitudinal direction thereof, that is, in the extending direction of the outer rail 13, that is, in the circumferential direction. In view of this, they are alternately formed at a predetermined interval so that they do not overlap each other. The base end of the sliding plate 27 is fitted into the end locking groove 28, and the intermediate portion of the sliding plate 27 is formed by the support protrusion 32 so as to substantially contact the inner surface of the outer rail 13. It is fitted in the formed groove portion and is locked by the locking projection 31. Further, as shown in FIG. 2, the tip of the sliding plate 27 is fixed together with the return rubber 26 being attached to the outer rail 13. In the above example, the locking projection 31 and the support projection 32 are formed so as not to overlap each other when viewed in the circumferential direction.
This is only configured in order to smoothly perform the die-cutting when molding the front frame 3, and if the shapes do not cause the problem of die-cutting, they may overlap each other in the circumferential direction. You may give a positional relationship. Also, the locking protrusion 3
Although the sliding plate 27 can be effectively positioned by alternately forming 1 and the supporting protrusion 32, it is not always necessary to alternately provide the sliding plate 27. Note that the sliding plate 27 may be attached using an adhesive tape, an adhesive, or the like instead of or in addition to the attachment by the locking protrusion 31 and the support protrusion 32. Further, if the game ball B passes only the central portion in the width direction of the sliding plate 27,
A locking mechanism may be provided on both sides thereof. For example, the sliding plate 17 is attached by pressing locking claws on both sides of the sliding plate 27 in the width direction and locking the locking claws in the locking holes formed in the outer rail 13. May be

Under such a structure, the extension of the game area is mainly determined by the window hole on the inner peripheral side of the front frame 3, and in the state where the game board 5 is attached to the front frame 3, The inner rail 12 and the outer rail 13 are in contact with or close to the game board 3. Therefore, the external appearance is as if the inner rails and the outer rails were attached to the game board as in the conventional case. Further, as a result, even if the game board 5 is replaced with another one, the entire front frame 3 including the inner rails 12 and the outer rails 13 can be shared, so wasteful disposal can be prevented and excellent recyclability is achieved. It becomes a thing. Similarly, the sliding plate 27
Since it is merely hooked on the locking projection 31 and the support projection 32, the sliding plate 27 can be easily removed and replaced, and the material can be sorted and discarded for each material.

The game ball B launched by the game ball launching device is guided to the upper part of the game area mainly by the outer rail 13 and directly by the sliding plate 27. The return ball prevention member 34 is provided at the tip of the inner rail 12.
Has been attached. This prevents the situation where the game ball B once guided from the tip of the inner rail 12 to the upper part of the game board 5 returns to the launch passage between the inner rail 12 and the outer rail 13 again. Has become.

Further, in this embodiment, the game area formed by the game board 5 and the front frame 3 is much larger than the conventional one. In the present embodiment, the distance from the uppermost point of the outer rail 13 to the upper portion of the outlet 25 (the lower portion of the game board 5) is 462 mm (75 m more than the conventional product).
m), and the distance from the extreme left position of the outer rail 13 to the extreme right position of the inner rail 12 is 449 mm (6 mm longer than the conventional product).
5 mm longer). The distance from the far left position of the inner rail 12 to the far right position of the inner rail 12 is 43
It is 2 mm.

The width (left and right width) of the game area is preferably at least 400 mm or more. More preferably 410 mm or more, 420 mm or more, 430 mm or more,
It is more preferable that it is 440 mm or more and 450 mm or more, and further 460 mm or more. Of course, it may be 470 mm or more, 480 mm or more, 490 mm or more. Also, the height of the game area (upper and lower width) is at least 400m.
It is desirable that m or more. More preferably 410 mm
As described above, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, 470 mm or more, 480 mm
It may be 490 mm or more. It should be noted that the above numerical values may be arbitrarily combined with respect to the combination of the width and the height. As a result, the area ratio of the game area to the surface of the game board is about 75%, which is much larger than the conventional one. The area ratio of the game area to the surface of the game board is preferably 60% or more. It is more preferably 65% or more, and further preferably 70% or more. Further, it is more desirable if it is 75% or more as in the above example. Further, it may be 80% or more.

Further, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 1 is about 40%, which is much larger than the conventional one. The area ratio of the game area to the front side area of the entire pachinko machine 1 is 3
It is preferably 5% or more. Of course, it may be 40% or more, 45% or more, or 50% or more.

However, in the present embodiment, a part of the outer rail 13 (including the extreme left part) is projected outside the game board 5 in order to enlarge the game area as described above. ing. In other words, a part of the launch path of the game ball B to be launched, in other words, a part of the game area exists at a position protruding from the game board 5. With such a configuration, a wide game area can be secured in the left-right direction, and a sufficient game ball dropping area can be secured even when a large variable display device 9 is installed.

The passage opening 10 located on both sides of the variable display device 9 has a guide mechanism for allowing the game ball B passing through the passage opening 10 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 8 and the variable winning device 7, and the game area is expanded. As a result, it is possible to prevent a decrease in interest due to difficulty in winning the game ball B. Furthermore, because the game area is expanded in the left-right direction,
The passage opening 10, a plurality of nails (guide nails such as triangular nails for guiding the game ball B to the center), and other accessories can be arranged in various ways, and in the game areas on the left and right sides of the variable display device 7. The behavior of the game ball B can be made more interesting.

Further, as described above, the lead-out portion 18 is arranged so as to project downward from the arc shape formed by the inner rail 12. That is, the outlet 25 is arranged at a position below the game area. As a result, it is possible to secure a wide game area in the vertical direction, and also to secure a sufficient game ball drop area even when a large variable display device 9 is installed. Therefore, the general winning opening 6, the variable winning device 7, the operation opening 8, the variable display device 9 and the like can be arranged without being restricted, and the nails, the windmill, etc. can be arranged without being restricted. It is composed.

For example, in the present embodiment, the variable winning a prize device 7 (which constitutes one of the game machines) is the outlet 2.
5 is provided immediately above, that is, almost at the bottom of the game board 5. As a result, the area above the attacker (opening / closing plate) of the variable winning device 7 becomes wider. Therefore, the distance between the variable winning device 7 and the variable display device 9 can be made wider than in the conventional case.

Therefore, the variable winning device 7 and the variable display device 9
In comparison with the conventional case in which the working port has to be tightly arranged between the above and, the working port 8 can be arranged with a margin. Further, since the interval between the variable winning device 7 and the variable display device 9 is widened, it is possible to dispose an additional game device there. Furthermore, since a large number of nails and the like can be planted flexibly above the attacker of the variable winning device 7, the impact of the game ball B can be mitigated, and thus the variable winning device 7 and the ball receiving member 17 etc. can be damaged. This can be prevented, and the game ball B can be easily rectified (for example, the game ball B is guided to the variable winning device 7 at the time of a big hit). Also, in consideration of the fact that the game ball B guided to the outlet 25 is almost invisible, it is possible to feel as if most balls were being guided to the variable winning device 7 at the time of a big hit. It has become. Further, the lower shape of the mounting substrate of the variable winning device 7 can be formed in an arc shape along the inner rail 12. Therefore, it is possible to significantly improve the appearance quality.

FIG. 8 is a rear view of the glass door frame 4. As shown in the figure, the glass door frame 4 is provided with a substantially circular window portion 41 so that most of the game area can be visually recognized from the outside. In the present embodiment, the distance between the upper end of the window 41 (the uppermost part of the outer rail 13 and the upper end of the game area) and the upper end of the glass door frame 4 (the so-called upper frame vertical width) is 50 mm. Has become 8
The width is significantly shorter than that of the prior art having an upper frame width of about 5 mm to 95 mm. As a result, the upper area of the game area is easily secured, and the large-sized variable display device 9 can be arranged relatively above. The distance is preferably 80 mm or less, more preferably 70 mm or less, and further preferably 60 mm or less. Of course, if the predetermined strength can be ensured, it may be 50 mm or less.

Further, the shortest distance between the left end of the window 41 and the left end of the glass door frame 4 (so-called left-right width of the left frame part: displayed on the right side in the figure) is the glass door frame 4 itself. Is set to be relatively large in order to increase the strength and the supporting strength. More specifically, as is apparent from a comparison between FIGS. 1 and 2, when the glass door frame 4 is closed, not only the left end of the outer rail 13 but also the left end of the inner rail 12 is the left side frame. Covered by parts. That is, a part of the guide rail is covered. Even if it becomes difficult to visually recognize the game ball B in the course of launching in this way, it is only a passing point where the game ball B is guided to the game area, and the game is mainly performed in the main part of the game area where the player enjoys the game. The sphere B is not difficult to see. Therefore, no trouble occurs in the actual game.

Further, while such a problem does not occur,
Sufficient strength and supporting strength of the glass door frame 4 can be secured. By the way, the left end position of the outer rail 13 and the outer frame 2
The lateral distance from the left end position is 21 mm, and the lateral distance from the right end position of the game area (the right end position of the inner rail 12) and the outer frame 2 right end position is 44 mm.

Generally, the visual field of a person (when the line of sight and the head are not moved) is set to about 25 degrees above the horizontal line of the eye in the vertical direction and about 35 degrees below the horizontal line of the eye. Also,
In the horizontal direction, 40 degrees to the left and right centered between the eyes, that is,
It is said to be within 80 degrees. And the player and the game board 5
Assuming that the distance is about 550 mm, for example, the right and left widths are preferably 700 mm or less, more preferably 650 mm or less, and even more preferably 600 mm or less as an appropriate size of the game area. Further, it may be 550 mm or less. Furthermore, it is desirable that the vertical width (height) be within 650 mm.
It is more desirable to be within 00 mm. Further, it may be within 550 mm.

Further, as shown in FIGS. 8 and 9, a glass support metal frame 42 is provided on the back side of the glass door frame 4, and a pair of rectangular glass 4 is provided on the glass support metal frame 42.
3, 44 are attached to the front and the rear at predetermined intervals. Glass support metal frame 4 with the same clearance as a conventional pachinko machine in order to support the vast game area as described above.
If the size of the glasses 43 and 44 is determined to be 2, the glasses 43 and 44 will be very large. Since the weight of the glasses 43 and 44 directly acts on the glass door frame 4, it is not a good idea to use the heavy glasses 43 and 44 in the glass door frame 4 whose frame strength corresponding to a wide game area is not so high. . Therefore, in the present embodiment, in order to minimize the areas of the glasses 43 and 44, the portion corresponding to the left side frame portion of the glass supporting metal frame 42 is located near the window portion 41. As a result, the total weight of the glasses 43 and 44 is suppressed to some extent, and the burden on the frame of the glass door frame 4, especially the left side frame part is reduced.

On the other hand, with the above-mentioned configuration, in the state where the glass door frame 4 is closed, the far left part of the launch path of the game ball B constituted by the outer rail 13 and the inner rail 12 And the vicinity thereof, that is, a part (left end part) of the guide rail has a part which is not covered with the glass 44 on the back side. That is, in the closed state of the glass door frame 4, a portion not covered with the glass 44 becomes a gap. And if the gap portion is not covered at all, for example, when the game ball B that has been fired returns without reaching the return ball prevention member 34, the game ball B spills from the gap to the front side ( There is a risk of jumping out). In order to prevent such a situation, in the present embodiment, the portion of the glass supporting metal frame 42 corresponding to the extreme left portion and its vicinity is not for supporting the glass 44, but for the glass 4
Instead of 4, it is folded back to cover the gap. The cover portion (cover member) 45 is configured by the folded-back portion. Therefore, even if the game ball B returns, the problem that the game ball B is spilled to the front side due to the presence of the cover portion 45 is avoided, that is, the fall prevention function of the game ball B is put in other words. ,
The function of forming a reliable launch path (guide rail) is fulfilled. Therefore, the guide rail is constituted by the inner and outer rails 12 and 13 when seen in a plan view, but in detail (three-dimensionally), the guide rail is
It can be said that it is configured by the inner and outer rails 12 and 13 formed on the front frame 3, the glass 44 and the cover portion 45 provided on the glass door frame 4.

In addition, as shown in FIG. 2, the glass door frame 4
The lower portion of the front frame 3 in which the presence of the above is not present is a lower tray unit 51 made of, for example, ABS (acrylonitrile-butadiene-styrene) resin. From the lower right portion of the lower tray unit 51, a game ball launching handle 52 is extended to the front side. Further, a lower pan 53 for paying out a prize ball as a ball pan is provided at substantially the center of the lower pan unit 51.

On the other hand, the upper tray 54 as a ball tray is integrally provided on the lower frame of the glass door frame 4. That is, conventionally, a front decorative frame that can be opened and closed with respect to the front frame is provided below the glass door frame, and an upper saucer is provided on the front decorative frame, but in the present embodiment, the front decorative frame is The upper tray 54 is provided directly on the front frame 3 and is omitted.

This is because the size of the pachinko machine 1 itself is the same as before, but the game area is expanded vertically. That is, if the front decorative frame is provided as in the conventional case, the vertical width of the lower frame of the glass door frame must be reduced, and the strength of the glass door frame is reduced. In order to eliminate such inconvenience, in the present embodiment, the upper tray 54 is provided for the front frame 3, whereby a sufficient vertical width of the lower frame of the glass door frame 4 can be secured, and thus, Sufficient strength of the glass door frame 4 is secured.

In this embodiment, a light emitting means such as various lamps is provided around the glass door frame 4 (for example, a corner portion). These light emitting means play a role of enhancing the effect during the game by controlling the light emitting mode such as lighting and blinking according to the change of the game state at the time of a big hit or a predetermined reach. Of course, the light emitting means such as these lamps may be provided in the game board 5 (an electric decoration member called a corner decoration is arranged in a corner portion or the like of the game board 5), or in some cases, the front frame 3 It may be configured to be provided in. Further, it may be arranged between the pair of front and rear glasses 43, 44.

As is well known, the front frame 3 is automatically locked when the front frame 3 is closed with respect to the outer frame 2, and the lock is released by a predetermined key operation. ing. Similarly, when the glass door frame 4 is closed with respect to the front frame 3, the lock is automatically applied, and the lock is released by performing a separate key operation. A lock mechanism for locking and unlocking in this manner is provided at the lower right portion of the front frame 3. The lock mechanism includes a key cylinder (release key) 55 having a keyhole, a first lock mechanism for locking and releasing the front frame 3 and the outer frame 2, and a glass door frame 4.
And a second locking mechanism for locking and unlocking between the front frame 3. In this embodiment, the narrowest width,
The lock mechanism including the key cylinder 55 (particularly the key cylinder 55) is provided not on the right center portion of the front frame 3 which hinders expansion of the game area but on the lower right portion of the front frame 3 which is relatively space-wise. Is provided. In other words, the key cylinder 55 is arranged so as to avoid the position where it has the maximum width of the game area.

With such a structure, the game area can be expanded more easily and surely. Further, it is usually necessary to provide a notch or a hole for disposing the key cylinder in the glass door frame 4 or the like. However, according to the above-mentioned configuration, a wide portion having a relatively high strength (right Since the notch or the hole for the key cylinder is provided in the lower portion, it is possible to suppress the strength reduction of the right side portion of the glass door frame 4 and the like.

Of course, except for the narrowest part,
It may be provided in a portion other than the above, for example, in the upper right portion of the front frame 3. Further, in the above example, both the first lock mechanism and the second lock mechanism can be released from the locked state by the key cylinder 55, but a key cylinder for releasing each may be provided separately.

As described above in detail, according to the present embodiment, the game board 5 is attached to the front frame 3 with the resin base 11. Here, the board surface peripheral edge of the game board 5 is supported by the first support frame portion, but with this, stable support of the game board cannot be expected as in the conventional structure. This becomes more remarkable when the support area by the first support frame portion is narrowed to expand the game area as in the present embodiment. In this respect, according to the present embodiment, the resin base 11 supports the game board 5 surface between the board surface peripheral edge of the game board 5 and the game area extension of the game board 5 in addition to the first support frame portion. Since it has two support frame portions, it is possible to expand the support area on the surface of the game board 5 and stably support the game board 5. Further, it is possible to reduce the warp of the surface of the game board 5 after the game board 5 is attached. In particular, in the present embodiment, the game area is formed with the circular shape as a basic shape, and the second support frame portion and the game are utilized by utilizing the non-game area portions of the four corners of the game board 5 surface. The board surface is brought into contact with and supported (see F portion in FIG. 2). Therefore, the four corners of the game board 5 can be supported in a wide area, and the wide support parts can be evenly distributed to the four corners, so that the game board 5 can be supported more stably. .

Further, since the front frame 3 is integrally formed including the support frame portion, the middle frame, which has been conventionally required, is not required, and the number of parts and the number of assembling steps can be reduced. The assembling error between the front frame 3 and the game board 5 after assembly can be reduced. Moreover, since the front frame 3 is made of synthetic resin, it can be easily manufactured by using a predetermined mold or the like.

Further, the resin base 11 is composed of a plate-like portion 14 which is substantially parallel to the surface of the game board 5 and a grid-like rib 15 which reinforces the plate-like portion 14. Therefore, the strength of the resin base 11 itself can be maintained. Also, resin base 1
Since the shape stability of 1 itself can be ensured, the game board 5 can be supported more stably. In addition, when the rib 15 is provided on the front side of the plate-shaped portion 14, the plate-shaped portion 14 and the game board 5 surface are directly contacted with each other, and the game board 5 surface is received by the resin base 11 by the surface. It will be. As a result, the game board 5 can be supported more stably.

At the same time, a window hole is formed in the resin base 11, and the exposed area of the game board 5 is formed by almost this portion, and the outer rail 13 and the inner rail 12 are integrally formed on the window hole side. For this reason, it is not necessary to perform the work of forming the game area by pressing the inner and outer rails and fixing them to the game board surface as in the conventional case. On the contrary, since the inner rail 12 and the outer rail 13 are integrally formed on the resin base 11, the rails 12 and 13 can be easily installed, and moreover, the outer rail 13 is protruded from the game board 5 surface as in the present embodiment.
Can be easily arranged.

In addition, if the outer rail 13 is allowed to function as it is as the outer rail 13, there is a disadvantage that the entire resin base 11 must be replaced when it is damaged. In the present embodiment, however, the sliding plate 27 is used. Therefore, the possibility of damage can be reduced and
Even if damage such as bending or deterioration occurs, the sliding plate 27
Only need to be replaced. Further, in the present embodiment, since the front frame 3 is made of synthetic resin, there is an advantage that the pachinko machine 1 can be easily sorted by material when it is discarded.

Further, in this embodiment, the sliding plate 2
Most of the parts 7 are fitted into the groove formed by the support projection 32, and are attached by being locked by the locking projection 31, so that a separate mounting member such as a screw is unnecessary. There are advantages. Further, since the groove portion and the locking projection 31 are arranged at positions where they do not overlap each other when viewed in the longitudinal direction, it is possible to easily perform die cutting when the front frame 3 is manufactured by a die. In particular, since the groove portions and the locking projections are provided alternately, the sliding plate 27 can be supported substantially evenly on both sides in the width direction, even though the sliding plate 27 has a simple structure. The possibility of slipping out is reduced. In addition to the above, the base end portion of the sliding plate 27 is fitted in the end portion locking hole 28, and the tip end portion is fixed together with the return rubber 26 being attached to the outer rail 13. .
Therefore, the mounting structure of the sliding plate 27 is simple.

Further, the ball receiving member 1 is provided in the vicinity of the outlet 25.
Since 7 is arranged, the possibility that the inner rail 12 made of resin will be damaged is reduced in the vicinity of the outlet 25 where the game ball B can hit the game area B at a relatively high speed. Particularly, in the present embodiment, the rib 2 is provided on the lower surface of the ball receiving member 17.
3, 24 are formed, and by their presence, the guide portion 1
9 etc. are reinforced. Furthermore, a slight gap is formed between the inner rail 12 and the guide portion 19, a predetermined elasticity is given to the guide portion 19, and even when the game ball B hits the guide portion 19 or the like, the impact force is generated by the elasticity. As a result, the ball receiving member 17 is less likely to be damaged. As a result, the above effect can be made more reliable. Further, since the ball receiving member 17 is attached alone, a separate member for attachment (such as a screw) is also unnecessary. Further, the locking projection 22 is provided on the lower portion of the ball receiving member 17.
Is integrally formed, and is configured to be engaged and retained in the locking hole 21 on the inner rail 12 side. For this reason, the work of assembling the ball receiving member 17 is facilitated, and the ball receiving member 17 can be detached and replaced if necessary.

In addition, the ball receiving member 17 is constructed so that it can be inserted into the inner rail 12 from the front side, and when the glass door frame 4 is in the closed state, the glass door frame 4 allows a space for slipping out to the front side. Have been lost. for that reason,
It is possible to easily prevent the ball receiving member 17 from falling off without using extra parts.

The contents described in the above-mentioned embodiment are not limited to the above, and the following may be adopted, for example.

(A) In the above embodiment, the inner rail 12 is
