Therefore, the base member 78 can be attached to the right frame 36 after the rotational displacement member 112 is attached to the base member 78 in advance. Therefore, the assembly work of the base member 78 and the rotational displacement member 112 can be performed efficiently.

  Next, an operation of the gaming machine locking device according to the second embodiment of the present invention will be described. For simplification of description, in the following description, the upper part of the locking device will be mainly described, and detailed description of the operation and effect of the same configuration as that of the first embodiment will be omitted. To do.

  When the front frame 13 is pushed into the outer frame 12, the receiving portion engaging portion 72 engages with the lower end of the locking receiving portion 81 as shown in FIGS. Tilts downward. When the front frame 13 is further pushed into the closed position, the top of the receiving portion engaging portion 72 goes under the locking receiving portion 81, and the receiving portion engaging portion 72 is hooked on the locking receiving portion 81. At this time, the tip of the left / right direction movement restricting pin 74 is guided by the guide portion 91 and comes into contact with the receiving seat 90, and the locking metal fitting contact portion 75 comes into contact with the left / right direction movement restricting portion 82. The horizontal swing of 44 is restricted, and the horizontal swing of the front frame 13 with respect to the outer frame 12 is suppressed (see FIG. 19).

  Next, in a state where the receiving portion engaging portion 72 is hooked on the locking receiving portion 81 in this way, the operating tool 121 is engaged with the engaging groove portion 120 of the operating portion 114 from the front side of the front frame 13, and the operation is performed. The tool 121 is rotated leftward when viewed from the front. Then, the hook member abutting portion 116 rotates in the same direction, and the front and rear between the base end surface 73 of the hook member 44 and the rear surface of the lock receiving portion 81 as shown in FIGS. 17 (b) and 20 (b). The hook member contact portion 116 enters the gap 100 in the direction.

More specifically, for example, as shown in FIG. 22A, in an ideal case where there is no gap 100 in the front-rear direction between the base end surface 73 of the hook member 44 and the rear surface of the lock receiving portion 81. The rotation of the hook member abutting portion 116 is stopped at the position where the hook member abutting portion 116 is in the vicinity of the receiving portion engaging portion 72 of the hook member 44 or the position where the receiving portion engaging portion 72 abuts. On the other hand, as shown in FIG. 22 (b), in case the gap 100 is wide (in the case of u _1), the rotation angle of the hook member abutment 95 is increased, deeply enters the gap 100, and FIG. as shown in 22 (c), in case the gap 100 is narrow (for _{u 2),} the rotation angle of the hook member abutment 95 is reduced, enters shallow gap 100. In both cases, the gap 100 is closed by the hook member abutting portion 116, thereby restricting the movement of the hook member 44 in the front-rear direction, and swinging the front frame 13 in the front-rear direction relative to the outer frame 12. Movement is suppressed. Further, the front frame 13 is biased toward the outer frame 12 so as to match the setting of the adjustment gauge.

  In this case, the inclination angle β of the inclined surface 97 of the hook member abutting portion 116 is set to be equal to or less than the inclination angle α of the base end surface 73 of the receiving portion engaging portion 72 (see FIG. 23). The rotating operation of the hook member contact portion 116 is performed smoothly and reliably.

  Next, the lower part of the locking device 15 will be described with reference to FIG.

  In the lock fitting 35, an operation hole 122 through which the operation tool 121 can be inserted is formed in the fixed piece 40 of the base plate 38. In the first elevating rod 46, the proximity portion 123 of the operation hole 122 is bent toward the standing piece 41 side of the base plate 38, so that it does not interfere with the operation tool 121 inserted through the operation hole 122. . Then, by forming the lower portion of the locking fitting 35 in this manner, the operation tool 121 can be engaged with the engagement groove portion 120 of the operation portion 114 via the operation hole 122 also in the lower locking device. Therefore, the rotational displacement member 112 can be operated from the front side of the front frame 13.

  In the above-described second embodiment, both the upper and lower locking devices are configured to be operable from the front side of the front frame 13, but for example, the locking device according to the above-described first embodiment. Alternatively, as in the modified example shown in FIG. 24, the engagement groove portion 125 is formed on the rear end side of the hook member abutting portion 124 of either one of the locking devices 15 and can be operated from the back side of the front frame 13. You may comprise as follows. With this configuration, when the upper and lower locking devices 15 are operated, first, the hook member abutting portion 124 is directly operated from the back side of the front frame 13 to suppress the swinging in the front-rear and left-right directions. , The other hook member abutting portion 116 can be operated from the front side of the front frame 13 using the operation tool 121.

  That is, after the pachinko gaming machine 11 is shipped, on the production line, with the front frame 13 set on the outer frame 12, the swing prevention mechanism is operated and adjusted while being visually observed from the back side, and then the swing prevention is performed. Based on the mechanism, the other swing prevention mechanism can be operated and adjusted from the front side of the front frame 13, and in the process until the pachinko gaming machine 11 is mounted on the game island after shipping, Even if the gap 100 is formed, the other swing prevention mechanism can be operated and adjusted from the front side of the front frame 13. Therefore, the operation, adjustment and fine adjustment of the swing prevention mechanism can be performed easily and reliably, and the swing prevention of the front frame 13 can be performed more reliably and more suitably.

  Further, in the second embodiment, the hook member abutting portion 116 is rotatable in the right direction when viewed from the back side, but as shown in FIG. 24, it can be rotated in the opposite left direction. The inclined surface 126 may be formed in the opposite direction to that described above.

  Furthermore, as shown in FIG. 24, a screw portion 128 may be formed on the rotational displacement member 127 so that the rotational displacement member 127 can be screwed into the lock receiving portion 81. In this case, the rotation displacement member 127 is displaced in the front-rear direction with respect to the lock receiving portion 81 by the screwing operation of the screw portion 128 in addition to the rotation operation of the rotation displacement member 127. After the rotation displacement member 127 is rotated and adjusted from the side, the screw portion 128 is further rotated from the front side of the front frame 13 via the operation portion 114, whereby fine adjustment can be performed.

  In the first and second embodiments, as the left-right swing restraining mechanism, the left-right direction movement restricting pin 74 that is a side abutting portion is provided on the hook member 44 side, and the side to be locked on the locking bracket 37 side. Although the receiving seat 90 which is a side contact portion is provided, conversely, a side contact portion may be provided on the hook member 44 side and a side contact portion may be provided on the lock receiving bracket 37 side.
