By combining 9 rails, the rails 27 to 29 are fixed integrally with the front frame 7, that is, after mounting, so as not to move relative to the front frame 7 even when the glass plate is taken in and out. . In this state, the glass plate 26 having a thickness of about 3 mm is provided between the first piece 30 and the second piece 31 and between the second piece 31 and the third piece 32 of each rail 27 to 29 (both are (Slightly larger than the thickness of the glass plate 26)
Is inserted from above.

In such a pachinko machine 1, the rail ribs 17 to 17 on the rear surface of the front frame 7 which is provided on the side edge of the front frame 7 can be opened and closed.
Since the corresponding rails 27 to 29 are attached to 19 by hooking the hook portions 33, the support structure for the glass plates 26, 26 can be formed or removed with one touch. In addition, rails 27 to 29 and base 1
Even if 2 and the like are molded with synthetic resin, the glass plates 26, 26 can be sufficiently supported and the front frame 7 as a whole can be made lightweight. As a result, the front frame 7 can be easily handled during manufacturing or maintenance.

Further, the end portions of a plurality of rails and the end portions of the adjacent rails are combined to form a right rail 29 and a lower rail 2.
7 and the left rail 28, the left rail 2
Since all the rails 27 to 29 are fixed only by engaging the fixing member 50 only near the upper end of 8, the fixing work for completing the attachment becomes simple, and the rails 27 to 2
9 is integrated with the front frame 7 after mounting, and has a simple structure and is advantageous in strength. Here, since the closing member 45, which is a part of the lock mechanism, is also attached by the fixing member 50 at the same time, the front frame 7 can be handled more easily.

Further, since the lower rail 27 is provided with the reinforcing portion 34 which is excellent in fatigue resistance and abrasion resistance, even if a game ball collides, it is possible to prevent cracking or chipping. Here, during the game on the pachinko machine 1, the game balls that have not won the winning device reach the bottom of the circular game area (located at the center in the left-right direction) and are seen from the front for collection. The rails are guided to the back and fall from the bottom of the front frame 7 in the back as soon as they are seen, while the winning game balls fall from the back as seen from the front. Two
Of 7-29, there is a possibility of collision with the game ball,
It is the central part of the lower rail 27 on the front side when viewed from the back,
Therefore, the reinforcing portion 34 occupies a necessary and sufficient position and range. Further, since the reinforcing portion 34 closes the hole provided when the central hook portion 33 is formed, it is possible to improve the strength and to prevent a fraudulent activity by eliminating a gap for a tool to enter.

Since the rail ribs 17 to 19 are integrally formed in a U-shape that surrounds three sides at the edges,
The front frame 7 as a whole can resist warping or twisting, the front frame 7 can be formed with high strength, and the ribs do not have to be stretched around, so that the front frame 7 can be easily formed. Further, the mounting strength of each rail 27 to 29 can be improved. Further, since the closing member 45 is fixed by the pressure contact of the closing member rib 46 and the engagement of the hook piece 44 with the hook portion 47, the closing member 45 can be sufficiently fixed to the front frame 7. It is possible to prevent the situation where the front frame 7 is opened even though it is locked.

[Second Embodiment] The pachinko machine according to the second embodiment is the same as the pachinko machine of the first embodiment except for the back surface of the base 58 of the front frame 57 shown in FIG.
