The machine frame mounting member 12 in the present invention may have any structure as long as it can be easily mounted on the machine frame 11 of the pachinko machine 2. For example, as shown in FIG.
It is also possible to avoid the hinge 11 ′ and to sandwich the hinge 11 in the machine frame 11. As shown in FIG. 8, the machine frame mounting member 12b has a fixing piece 35 riveted to the above-mentioned engaging member 15 so that a nipping portion 36a made of a metal plate extends laterally from the upper end of the fixing piece 35. At the same time, the base end of the engaging member 15 is riveted to the lower surface of the engaging member 15 so that the sandwiching portion 36b made of a metal plate extends substantially parallel to the sandwiching portion 36a.
Claws 37 ... Are formed toward the holding space 38 at the tip of
A metal wire opening operation portion 39, which is longer than the holding portion 36a, is rotatably attached to the tip portion of one holding portion 36a. The space between the sandwiching portions 36a and 36b, that is, the sandwiching space 38, is set to be slightly wider than the thickness of the plate material forming the machine frame 11 of the pachinko machine. Therefore, as shown in FIG. 9, when the opening operation portion 39 and the engaging member 15 are strongly pinched with, for example, the thumb and the index finger, the distance between the tips of the holding portions 36a and 36b becomes larger than the thickness of the plate material of the machine frame 11. . In this state, as shown by the two-dot chain line in FIG. 9, when the plate material of the machine frame 11 is inserted into the holding space 38 and the finger is released, both holding portions 36
The elasticity of a and 36b restores the distance between the tips of the holding spaces 38, and the claws 37 at the tips are pressed against the plate material of the machine frame 11. Then, when the tip portions of the sandwiching portions 36a and 36b are hit with a hammer or the like, the claws 37 ... Are hit into the plate material of the machine casing 11, so that the machine casing mounting member 12b is firmly attached to the rear portion of the machine casing 11. As shown in FIG. 9, the machine frame mounting member 12b can be shared by mounting the machine frame 11 on the upper horizontal plate member and the lower horizontal plate member upside down.

Further, as shown in FIGS. 10 and 11, the machine frame mounting member 12c is integrally formed with the engaging member 15 by bending a single metal plate, and You may make it easy to fix to the upper surface of a cross member with a wood screw.

Further, in the present invention, in order to avoid the hinge 11 ′ of the machine frame 11, the sandwiching type machine frame mounting member 12 b is used.
The machine frame mounting members 12a, 12b, 12c may be used in an appropriate combination, for example, the corner type machine frame mounting member 12a described above may be used in the upper part of 1 and the lower part of the machine frame 11.

Further, as shown in FIG. 12, it is desirable that the engaging projection 29 of the engaging member 15 be inclined slightly toward the hook 13 side from the vertical, and this inclination angle is drawn around the shaft 22. An angle corresponding to the locus of the engaging recess 24 of 13 is desirable. When the engaging projection 29 is tilted in this manner, when the engaging recess 24 of the hook 13 is engaged with the engaging projection 29, it is located between the inner edge of the engaging recess 24 and the engaging projection 29. There is almost no play. For example, as shown in FIG. 13, even if the hook 13 is stopped before returning sufficiently and rotating, the opening tip of the engaging recess 24 abuts on the engaging projection 29, so that there is no backlash. Therefore, when the pachinko machine 2 is attached to the island, the pachinko machine 2 caused by the fasteners 10 ...
There is almost no change in the inclination angle, and the hook 13 can be smoothly operated even when it is engaged with or disengaged from the engaging member 15.

<Effects of the Invention> As described above, according to the present invention, it is extremely easy to install the fastening device itself such as attaching the machine frame mounting member to the machine frame of the pachinko machine or attaching the rotating hook member to the island. Can be done.

Then, after attaching the fastener, the engaging projection of the engaging member engages with the engaging recess formed in the hook of the rotating hook member by simply pushing the pachinko machine into the installation space of the island.
You can fasten the pachinko machine to the horizontal material of the island with one touch. Therefore, the pachinko machine can be installed remarkably easily as compared with the conventional method of driving a nail, and since there is no impact of hitting a nail, the pachinko machine can be reliably mounted at a predetermined position set in advance.

Further, since the engaging projection can be removed from the engaging recess simply by rotating the hook by hand, the pachinko machine installed on the island can be easily removed. Therefore, even when a large number of pachinko machines are replaced with new pachinko machines within a short time after the store is closed, the time required to replace the pachinko machines is significantly shortened as compared with the conventional one, and the work can be performed efficiently.
