When the shaft main body 72 is inserted into the upper and lower shaft holes 66 and 67 and attached to the member main body 62, the upper hinge shaft 70 has the lower shaft hole 67 at the lower portion of the shaft main body 72 whose downward displacement is restricted by the restriction portion 73. The lower support plate 65 extends downward, and the lower portion of the shaft main body 72 serves as a locking end 74. A locking member 75 is attached to the locking end 74.

  As the locking member 75, a snap ring such as an E-ring, a snap retainer (Dalma pin) or an O-ring that is fitted to the peripheral surface of the locking end 74, or penetrates the locking end 74 in the radial direction. A split pin or an R pin (snap pin) that fits into the formed locking hole protrudes radially outward from the peripheral surface of the locking end 74 and falls off the locking end 74. Various difficult configurations can be used. As shown in FIG. 8C, in the embodiment, an E-ring is employed as the locking member 75. The locking member 75 attached to the locking end 74 is set to be larger than the lower shaft hole 67 and cannot pass through the lower shaft hole 67. The locking end portion 74 has a circumferential surface at a portion that is immediately below the lower support plate portion 65 in a state where the downward displacement of the shaft main body 72 is restricted by the engagement between the restriction portion 73 and the upper support plate portion 64. A locking groove 74a is formed by being further recessed (see FIG. 10), and a locking member 75 is fitted into the locking groove 74a. The locking member 75 may be detachable from the circumferential surface of the locking end portion 74 in the radial direction, but is not movable or difficult to move in the axial direction of the upper hinge shaft 70 with respect to the locking end portion 74. Established. That is, the hinge member 60 can remove or attach the upper hinge shaft 70 to the member main body 62 by making the locking member 75 detachable from the locking end portion 74.

  In the hinge member 60, the restricting portion 73 is hooked on the upper surface of the upper support plate portion 64 to restrict the downward displacement of the upper hinge shaft 70. This state is maintained by the weight of the upper hinge shaft 70, and the locking member 75 is lowered. The upper displacement of the upper hinge shaft 70 is restricted by being caught on the lower surface of the support plate portion 65. The hinge member 60 is aligned with the shaft holes 66 and 67 at two positions, ie, an upper position and a lower position of the shaft main body 72, so that the movement in the radial direction is restricted, and the shaft end portion 71 is connected to the upper portion of the upper coupling portion 32. The load applied to the upper hinge shaft 70 when fitted into the bearing hole 36 is distributed and received by the upper and lower support plate portions 64 and 65. It should be noted that rotation about the axis about the vertical direction of the upper hinge shaft 70 relative to the member main body 62 is allowed. By configuring the upper hinge shaft 70 to be rotatable with respect to the member main body 62, mutual sliding resistance can be reduced when the upper connecting portion 32 is inserted into and removed from the upper bearing hole 36, and the upper portion of the front frame 13 is moved upward. The hinge mechanism can be attached to and detached from the middle frame 12 smoothly.

Is placed on the front side of the front frame base part 42, and the connecting plate part 63 is placed on the rear surface of the front frame base part 42 and fixed with screws. Here, the connecting plate portion includes a screw through hole 63a through which a screw to be screwed into the screw hole 42c of the front frame base portion 42 is inserted, and a positioning pin 42d protruding rearward on the rear surface of the front frame base portion 42. The positioning hole 63b to be fitted is formed, and the hinge member 60 can be positioned on the front frame base portion 42 by the engagement between the positioning pin 42d and the positioning hole 63b. Further, the front side of the hinge member 60 installed on the front frame base portion 42 is formed in a concave shape opened rearward so that the support plate portions 64 and 65 projecting to the front side of the front frame base portion 42 and the upper hinge shaft 70 can be accommodated. The hinge cover member 78 is attached (see FIG. 3). The hinge cover member 78 covers the front side of the hinge member 60 and the upper part of the left side surface of the front frame base portion 42 over the hinge receiving groove 42b, and hides the hinge receiving groove 42b. The front side of the hinge cover member 78 is covered with the upper decorative member 43. In addition, the left end portion of the upper reinforcing member 49 attached to the rear surface of the front frame base portion 42 is connected to the connection plate portion 63 via the screw through hole 63a of the connection plate portion 63 facing the rear surface of the front frame base portion 42 in the hinge member 60.

Further, the left end portion of the front frame rear cover member 79 attached to the rear side of the upper reinforcing member 49 is connected to the connecting plate through the screw hole 63a of the connecting plate portion 63 facing the rear surface of the front frame base portion 42 in the hinge member 60. It is fixed with screws so as to overlap the portion 63.

(Effects of Example)
Next, the operation of the pachinko machine 10 according to the embodiment will be described. Since the upper hinge shaft 70 is supported at a position separated by the pair of support plate portions 64, 65, the load of the front frame 13 applied to the upper hinge shaft 70 can be distributed to both the support plate portions 64, 65. That is, the load applied to the upper hinge shaft 70 is received at two positions of the member main body 62 of the hinge member 60 instead of being received at one position of the member main body 62 of the hinge member 60 provided with the upper hinge shaft 70. Therefore, it is difficult for the upper hinge shaft 70 to be broken or bent at the support portion by the support plate portions 64 and 65, and the durability of the upper hinge shaft 70 can be improved. As described above, the upper hinge mechanism can maintain the proper posture of the front frame 13 even when the load of the front frame 13 is received, and can support the front frame 13 with respect to the middle frame 12 without misalignment. it can. In particular, the front frame 13 of the embodiment includes the decorative members 43 to 46 that protrude greatly forward, and the movable effect device 76 that is disposed on the upper ball tray 14 and can perform an operation effect by a large movable body. However, since the support capability of the upper hinge mechanism is high as described above, the front frame 13 can be supported appropriately. Since the front frame 13 constituting the front surface of the pachinko machine 10 can be appropriately supported by the hinge mechanism with respect to the middle frame 12 in this way, the front frame 13 is misaligned with the middle frame 12 and the design is damaged, or a shot is launched. A member disposed on the inner frame 12 such as the device 28 or a member disposed on the rear surface of the front frame 13 such as a ball feeding device interferes, or pachinko balls connected to the ball trays 14 and 15 from the inner frame 12. It is possible to prevent the occurrence of various problems such as a shift in the passage.

  The hinge member 60 is attached to the peripheral surface of the locking end portion 74 of the upper hinge shaft 70, and the locking member 75 that is hooked on the lower support plate portion 65 and the restriction of the upper hinge shaft 70 that is hooked on the upper support plate portion 64. With the portion 73, it is possible to prevent the upper hinge shaft 70 inserted through the shaft holes 66 and 67 of the both support plate portions 64 and 65 from coming off.
